PyTorch/TorchScript compiler for NVIDIA GPUs using TensorRT

Last update: Dec 30, 2022

Overview

Torch-TensorRT

Ahead of Time (AOT) compiling for PyTorch JIT

Torch-TensorRT is a compiler for PyTorch/TorchScript, targeting NVIDIA GPUs via NVIDIA's TensorRT Deep Learning Optimizer and Runtime. Unlike PyTorch's Just-In-Time (JIT) compiler, Torch-TensorRT is an Ahead-of-Time (AOT) compiler, meaning that before you deploy your TorchScript code, you go through an explicit compile step to convert a standard TorchScript program into an module targeting a TensorRT engine. Torch-TensorRT operates as a PyTorch extention and compiles modules that integrate into the JIT runtime seamlessly. After compilation using the optimized graph should feel no different than running a TorchScript module. You also have access to TensorRT's suite of configurations at compile time, so you are able to specify operating precision (FP32/FP16/INT8) and other settings for your module.

Building a docker container for Torch-TensorRT

We provide a Dockerfile in docker/ directory. It expects a PyTorch NGC container as a base but can easily be modified to build on top of any container that provides, PyTorch, CUDA, cuDNN and TensorRT. The dependency libraries in the container can be found in the release notes.

Please follow this instruction to build a Docker container.

docker build --build-arg BASE=<CONTAINER VERSION e.g. 21.11> -f docker/Dockerfile -t torch_tensorrt:latest .

In the case of building on top of a custom base container, you first must determine the version of the PyTorch C++ ABI. If your source of PyTorch is pytorch.org, likely this is the pre-cxx11-abi in which case you must modify //docker/dist-build.sh to not build the C++11 ABI version of Torch-TensorRT.

You can then build the container using:

docker build --build-arg BASE_IMG=<IMAGE> -f docker/Dockerfile -t torch_tensorrt:latest .

If you would like to build outside a docker container, please follow the section Compiling Torch-TensorRT

Example Usage

C++

#include "torch/script.h"
#include "torch_tensorrt/torch_tensorrt.h"

...
// Set input datatypes. Allowerd options torch::{kFloat, kHalf, kChar, kInt32, kBool}
// Size of input_dtypes should match number of inputs to the network.
// If input_dtypes is not set, default precision follows traditional PyT / TRT rules
auto input = torch_tensorrt::Input(dims, torch::kHalf)
auto compile_settings = torch_tensorrt::ts::CompileSpec({input});
// FP16 execution
compile_settings.enabled_precisions = {torch::kHalf};
// Compile module
auto trt_mod = torch_tensorrt::ts::compile(ts_mod, compile_settings);
// Run like normal
auto results = trt_mod.forward({in_tensor});
// Save module for later
trt_mod.save("trt_torchscript_module.ts");
...

Python

import torch_tensorrt

...

trt_ts_module = torch_tensorrt.compile(torch_script_module,
    inputs = [example_tensor, # Provide example tensor for input shape or...
        torch_tensorrt.Input( # Specify input object with shape and dtype
            min_shape=[1, 3, 224, 224],
            opt_shape=[1, 3, 512, 512],
            max_shape=[1, 3, 1024, 1024],
            # For static size shape=[1, 3, 224, 224]
            dtype=torch.half) # Datatype of input tensor. Allowed options torch.(float|half|int8|int32|bool)
    ],
    enabled_precisions = {torch.half}, # Run with FP16)

result = trt_ts_module(input_data) # run inference
torch.jit.save(trt_ts_module, "trt_torchscript_module.ts") # save the TRT embedded Torchscript

Notes on running in lower precisions:

Enabled lower precisions with compile_spec.enabled_precisions

The module should be left in FP32 before compilation (FP16 can support half tensor models)

Provided input tensors dtype should be the same as module before compilation, regardless of enabled_precisions. This can be overrided by setting Input::dtype

Bazel 4.2.1
Libtorch 1.10.0 (built with CUDA 11.3)
CUDA 11.3 (10.2 on Jetson)
cuDNN 8.2
TensorRT 8.0.3.4 (TensorRT 8.0.1.6 on Jetson)

Prebuilt Binaries and Wheel files

Releases: https://github.com/NVIDIA/Torch-TensorRT/releases

Compiling Torch-TensorRT

Installing Dependencies

0. Install Bazel

If you don't have bazel installed, the easiest way is to install bazelisk using the method of you choosing https://github.com/bazelbuild/bazelisk

Otherwise you can use the following instructions to install binaries https://docs.bazel.build/versions/master/install.html

Finally if you need to compile from source (e.g. aarch64 until bazel distributes binaries for the architecture) you can use these instructions

export BAZEL_VERSION=<VERSION>
mkdir bazel
cd bazel
curl -fSsL -O https://github.com/bazelbuild/bazel/releases/download/$BAZEL_VERSION/bazel-$BAZEL_VERSION-dist.zip
unzip bazel-$BAZEL_VERSION-dist.zip
bash ./compile.sh

You need to start by having CUDA installed on the system, LibTorch will automatically be pulled for you by bazel, then you have two options.

1. Building using cuDNN & TensorRT tarball distributions

This is recommended so as to build Torch-TensorRT hermetically and insures any bugs are not caused by version issues

Make sure when running Torch-TensorRT that these versions of the libraries are prioritized in your $LD_LIBRARY_PATH

You need to download the tarball distributions of TensorRT and cuDNN from the NVIDIA website.
- https://developer.nvidia.com/cudnn
- https://developer.nvidia.com/tensorrt
Place these files in a directory (the directories third_party/dist_dir/[x86_64-linux-gnu | aarch64-linux-gnu] exist for this purpose)
Compile using:

bazel build //:libtorchtrt --compilation_mode opt --distdir third_party/dist_dir/[x86_64-linux-gnu | aarch64-linux-gnu]

2. Building using locally installed cuDNN & TensorRT

If you find bugs and you compiled using this method please disclose you used this method in the issue (an ldd dump would be nice too)

Install TensorRT, CUDA and cuDNN on the system before starting to compile.

)

new_local_repository(
   name = "tensorrt",
   path = "/usr/",
   build_file = "@//third_party/tensorrt/local:BUILD"
)

Compile using:

bazel build //:libtorchtrt --compilation_mode opt

Debug build

bazel build //:libtorchtrt --compilation_mode=dbg

Native compilation on NVIDIA Jetson AGX

We performed end to end testing on Jetson platform using Jetpack SDK 4.6.

bazel build //:libtorchtrt --platforms //toolchains:jetpack_4.6

Note: Please refer installation instructions for Pre-requisites

A tarball with the include files and library can then be found in bazel-bin

Running Torch-TensorRT on a JIT Graph

Make sure to add LibTorch to your LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$(pwd)/bazel-Torch-TensorRT/external/libtorch/lib

bazel run //cpp/bin/torchtrtc -- $(realpath <PATH TO GRAPH>) out.ts <input-size>

Compiling the Python Package

To compile the python package for your local machine, just run python3 setup.py install in the //py directory. To build wheel files for different python versions, first build the Dockerfile in //py then run the following command

docker run -it -v$(pwd)/..:/workspace/Torch-TensorRT build_torch_tensorrt_wheel /bin/bash /workspace/Torch-TensorRT/py/build_whl.sh

Python compilation expects using the tarball based compilation strategy from above.

How do I add support for a new op...

In Torch-TensorRT?

Thanks for wanting to contribute! There are two main ways to handle supporting a new op. Either you can write a converter for the op from scratch and register it in the NodeConverterRegistry or if you can map the op to a set of ops that already have converters you can write a graph rewrite pass which will replace your new op with an equivalent subgraph of supported ops. Its preferred to use graph rewriting because then we do not need to maintain a large library of op converters. Also do look at the various op support trackers in the issues for information on the support status of various operators.

In my application?

The Node Converter Registry is not exposed in the top level API but in the internal headers shipped with the tarball.

You can register a converter for your op using the NodeConverterRegistry inside your application.

🐛 [Bug] Torch Tensor RT crash when trying to compile a script module on Windows (C++)

Bug Description

I can't compile a script module with TorchTensorRT. This is my code:

#include <iostream>
#include <vector>
#include <ATen/Context.h>
#include <torch/torch.h>
#include <torch/script.h>
#include "torch_tensorrt/torch_tensorrt.h"

void compile(std::string model_path) {

    const torch::Device device = torch::Device(torch::kCUDA, 0);
    torch::jit::script::Module model;

    std::cout << "Trying to load the model" << std::endl;
    try {
        model = torch::jit::load(model_path, device);
        model.to(device);
        model.eval();
        std::cout << "AI model loaded successfully." << std::endl;
    }
    catch (const c10::Error& e) {
        std::cerr << e.what() << std::endl;
    }

    auto input = torch_tensorrt::Input(std::vector<int64_t>{ 1, 3, 512, 512 });
    std::cout << "Creating compile settings" << std::endl;
    auto compile_settings = torch_tensorrt::ts::CompileSpec({ input });
    // Compile module
    std::cout << "Compiling..." << std::endl;
    auto trt_mod = torch_tensorrt::ts::compile(model, compile_settings);  <-- CRASHES HERE.
    // Run like normal
    std::cout << "Create tensor" << std::endl;
    auto in = torch::randn({ 1, 3, 512, 512 }, device);
    std::cout << "Forward pass..." << std::endl;
    auto results = trt_mod.forward({ in });
    // Save module for later
    trt_mod.save("output/model/path.ts");

}

int main() {

    compile("path/to/traced_script_module.pt");

    return 0;
}

This is the error I get:

First a WARNING get printed "WARNING: [Torch-TensorRT] - Interpolation layer will be run through ATen, not TensorRT. Performance may be lower than expected", and then, as you can see from the screenshot, I got an exception "read access violation. creator was nullptr." when running the following lines:

auto creator = getPluginRegistry()->getPluginCreator("Interpolate", "1", "torch_tensorrt");
auto interpolate_plugin = creator->createPlugin(name, &fc);

The file interpolate.cpp is located at path/to/Torch-TensorRT/core/conversion/converters/impl. What am I doing wrong?

This is my CMakeLists.txt:

cmake_minimum_required (VERSION 3.8)

project(example-app)

find_package(Torch REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")

add_executable(example-app create_trt_module.cpp)

target_include_directories(example-app PRIVATE "path/to/Torch-TensorRT/cpp/include")

target_link_libraries(example-app "${TORCH_LIBRARIES}")
target_link_libraries(example-app  path/to/Torch-TensorRT/out/build/x64-Release/lib/torchtrt.lib) 
target_link_libraries(example-app  path/to/Torch-TensorRT/out/build/x64-Release/lib/torchtrt_plugins.lib)

I exported the traced script module with the following code:

# Import model
# ...
model.to("cuda")
model.eval()

# Create dummy data for tracing and benchmarking purposes.
shape = (1, 3, 512, 512)
input_data = torch.randn(shape).to("cuda")

# Convert model to script module
print("Tracing PyTorch model...")
traced_script_module = torch.jit.trace(model, input_data)
torch.jit.save(traced_script_module, "traced_script_module.pt")

🐛 [Bug] Running a model that returns a tuple or list of size 2 or greater causes segfault

Bug Description

Running a model that returns a tuple (or list) of two or more tensors causes the program to segfault. Note that this does NOT occur when returning a tuple of only one tensor.

Returning a list of only one tensor will throw the following (presumably correct) error:

Traceback (most recent call last):

RuntimeError: [Error thrown at core/conversion/conversion.cpp:220] List type. Only a single tensor or a TensorList type is supported.

To Reproduce

Run the following (returning input directly to output):

  import torch    
  import torch_tensorrt as torchtrt    
      
  import torch_tensorrt.logging as torchtrt_logging    
      
  torchtrt_logging.set_reportable_log_level(torchtrt_logging.Level.Graph)    
      
  torch.manual_seed(0)    
      
  DEVICE = torch.device("cuda:0")    
  SHAPE = (3, 4)    
      
      
  class Model(torch.nn.Module):    
      def __init__(self):    
          super().__init__()    
      
      def forward(self, x):    
          y = x - x    
          z = x + x    
          return (x, z)    
      
      
  if __name__ == "__main__":    
      tensor = torch.randn(SHAPE, dtype=torch.float32, device=DEVICE)    
      
      model = Model().eval().to(DEVICE)    
      out = model(tensor)    
      print(out)    
      
      model_trt = torchtrt.compile(    
          model,    
          inputs=[    
              torchtrt.Input(shape=SHAPE),    
          ],    
          enabled_precisions={torch.float},    
      )    
      out_trt = model(tensor)    
      print(out_trt)    
      
      assert torch.max(torch.abs(out - out_trt)) < 1e-6

❓ [Question] Is it possibile to use a model optimized through TorchTensorRT in LibTorch under Windows?

❓ Question

I would need to optimize an already trained segmentation model through TorchTensorRT, the idea would be to optimize the model by running the newest PyTorch NGC docker image under WSL2, exporting the model and then loading it in a C++ application that uses LibTorch, e.g.

#include <torch/script.h>
// ...
torch::jit::script::Module module;
try {
  // Deserialize the ScriptModule from a file using torch::jit::load().
  module = torch::jit::load(argv[1]);
}

Would this be the right approach?

What you have already tried

At the moment I only tried to optimize the model through TorchTensorRT, and something weird happens. Here I'll show the results for the Python script below that I obtained on two different devices:

a Ubuntu desktop with a GTX1080Ti (that I use for development)
a Windows PC with a RTX3080 (that is my target device)

As you can see, the optimization process under WSL gives me a lot of GPU errors, while on Ubuntu it seems to work fine. Why does this happen?

My script:

import torch_tensorrt
import yaml
import torch
import os
import time
import numpy as np
import torch.backends.cudnn as cudnn
import argparse
import segmentation_models_pytorch as smp
import pytorch_lightning as pl
cudnn.benchmark = True

def benchmark(model, input_shape=(1, 3, 512, 512), dtype=torch.float, nwarmup=50, nruns=1000):
    input_data = torch.randn(input_shape)
    input_data = input_data.to("cuda")
    if dtype==torch.half:
        input_data = input_data.half()
        
    print("Warm up ...")

❓ [Question] Building torch_tensorrt.lib on Windows
❓ Question

I am wondering how to build the torch_tensorrt.lib on Windows.

What you have already tried

I have followed #960 and #856 (with the same WORKSPACE as the latter) and managed to successfully build torch_tensorrt.dll. However, I need the .lib file in order to compile my Libtorch program. I tried linking to some of the .lib files that were created already (like bazel-out\x64_windows-opt\bin\cpp\torch_tensorrt.lo.lib), but that didn't work. I expect it's a fairly simple bazel command, but I have no idea where to put it.

Environment

Build information about Torch-TensorRT can be found by turning on debug messages

PyTorch Version (e.g., 1.0): 1.10.0 (release)

CPU Architecture: x86-64

OS (e.g., Linux): Windows 10

How you installed PyTorch (conda, pip, libtorch, source): libtorch from pytorch.org

Build command you used (if compiling from source): bazel build //:libtorchtrt --compilation_mode opt

CUDA version: 11.3

Any other relevant information: Using VS2019

Additional context

My libtorch program runs fine even if I include the torch-tensorrt headers, but throws the following errors as soon as I try to use torch_tensorrt::torchscript::CompileSpec and call torch_tensorrt::torchscript::compile: Error LNK1120 2 unresolved externals Omkar 1.10.0+cu113 B:\Programming_Current Projects\HelloLibTorch\x64\Release\HelloTorch.exe 1

Add CMake support to build the libraries
Description

This PR adds the CMake support to build the libraries and the torchtrtc executable. It also generates a torchtrtConfig.cmake, in order to be able to consume these libraries with cmake targets.

The major advantage of the CMake support as introduced in this PR is the added ability to compile for windows as well, fixing the export of symbols, and generating both the *.dll and the *.lib libraries. To export the symbols, I reused the existing TORCHTRT_API macro, redefining it for windows, using CMake. The consumption of the dynamic libraries (both on linux and windows) is demonstrated by building the executable torchtrtc[.exe]. This has been tested locally with MSVC 2019 (19.29.30143.0), libtorch 1.11 (1.11.0+cu113), CUDA 11.6, cuDNN 8.2.1, and TensorRT 8.2.4.2. A secondary advantage is the handling of dependencies. These can be installed anywhere (not necessarily globally on the system) and by any mean and compiling the lib does not require editing config file anymore, instead, a few CMake variables are enough to have the dependencies correctly found and used. (for cuDNN and TensorRT, most of the magic happens in the CMake finders in cmake/Modules).

This PR only adds partial CMake support to Torch-TensorRT (only for the libs and the executable torchtrtc). I started working on the unit tests as well and could consider working on adding the python support as well, if there is a clear interest. I still think that being able to compile the libraries (also on windows) has value in itself, and that's the reason for this PR.

I didn't add any documentation about how to compile using CMake, but that should probably be done. A bit of guidance on where and how this should be best done would be appreciated.

With this PR, I also would like to trigger the discussion around CMake and/or windows support (which, technically, are obviously totally independent). The kind of questions I have are:

Is there a CI for this lib (I am assuming there is)? Could we imagine also compiling the lib with Cmake on the CI, to check that any new addition does not break it in the future? If not, how do you see the maintenance of the feature?

Same question for windows: I am assuming the lib is not compiled on windows on the CI currently. Can that be added? Possibly with CMake?

Thanks for reviewing and looking forward to answer questions 😃

Unable to use any Torch-TensorRT methods

I'm facing this error:

AttributeError: module 'torch_tensorrt' has no attribute 'compile'

I also get this error when I try to use any other method like Input().

This is how I installed Torch-TensorRT: pip install torch-tensorrt -f github.com/NVIDIA/Torch-TensorRT/releases

Code (from official documentation):

import torch_tensorrt

model = model.eval()
compile_settings = {
    "input_shapes": [
        {
            "min": [1, 1, 16, 16],

            "max": [1, 1, 64, 64]
        },
    ],
    "op_precision": torch.half # Run with fp16
}
enabled_precisions = {torch.float, torch.half}

trt_ts_module = torch_tensorrt.compile(model, inputs=compile_settings, enabled_precisions=enabled_precisions)

Stack Trace:

How to build from sources on Windows
❓ Question

How shall I edit the WORKSPACE file in order to build tag 0.1.0 from sources on Windows?

What you have already tried

I successfully did the build from sources process for Jetson Xavier AGX, see: https://github.com/NVIDIA/TRTorch/issues/222

Based on the material that I was already had from the Jetson process I tried to do the same for my Windows by editing the WORKSPACE based on my Windows setup. I changed all required new_local_repository arguments of the cuda, torch, cudnn and tensorrt based on my Windows installations

Activate the following command: bazel build //:libtrtorch

The following errors report was generated:

🐛 [Bug] Returning list of tensors fails when operations are applied to tensors: `RuntimeError: [Error thrown at core/conversion/conversion.cpp:220] List type. Only a single tensor or a TensorList type is supported.`

Bug Description

Returning a list of tensors fails when ops are applied to the tensors prior to appending them to the list that is returned. This is not the case if tensors are directly appended to the list without applying any operations.

RuntimeError: [Error thrown at core/conversion/conversion.cpp:220] List type. Only a single tensor or a TensorList type is supported.

To Reproduce

Run the following:

  import torch    
  import torch_tensorrt as torchtrt    
      
      
  import torch_tensorrt.logging as logging    
      
  logging.set_reportable_log_level(logging.Level.Info)    
      
  torch.manual_seed(0)    
      
  DEVICE = torch.device("cuda:0")    
  SHAPE = (1, 2)    
      
      
  class Model(torch.nn.Module):    
      def __init__(self):    
          super().__init__()    
      
      def forward(self, x):    
          tensors = []    
          for i in range(3):    
              y = x + x    
              tensors.append(y)    
      
          return tensors    
      
      
  if __name__ == "__main__":    
      tensor = torch.randn(SHAPE, dtype=torch.float32, device=DEVICE)    
      
      model = Model().eval().to(DEVICE)    
      out = model(tensor)    
      print(out)    
      
      model_trt = torchtrt.compile(    
          model,    
          inputs=[    
              torchtrt.Input(shape=SHAPE),    
          ],    
          enabled_precisions={torch.float},    
      )    
      out_trt = model(tensor)    
      print(out_trt)

This throws the following error:

feat: Show PyTorch code of unsupported operators
Signed-off-by: lamhoangtung [email protected]

Description

Inspired by my problem in #511, I'm trying to enable TensorRT for a TorchScript model and getting a bunch of Unsupported operators. I'm willing to change the implementation to avoid those unsupported operators or even trying to add support for it but struggling to find which line of code in my model are causing it.

Thanks to @narendasan guidance. I have tried to add a similar traceback feature like TorchScript where TRTorch will point to the exact line of PyTorch that cause the unsupported operators.

So instead of showing a vague operator schema like this:

ERROR: [TRTorch] - Method requested cannot be compiled by TRTorch. Unsupported operators listed below: - aten::__contains__.str_list(str[] l, str item) -> (bool) - ... You can either implement converters for these ops in your application or request implementation https://www.github.com/nvidia/TRTorch/issues

TRTorch should show the exact line of PyTorch that cause the unsupported operators like this:

ERROR: [TRTorch] - Method requested cannot be compiled by TRTorch. Unsupported operators listed below: - aten::__contains__.str_list(str[] l, str item) -> (bool) Related PyTorch code: File "/home/techainer/anaconda3/envs/test_pytorch/lib/python3.8/site-packages/torch/nn/functional.py", line 3446 ) if mode in ("nearest", "area"): ~~~~~~~~~~~~~~~~~~~~~ <--- HERE if align_corners is not None: raise ValueError( - ... You can either implement converters for these ops in your application or request implementation https://www.github.com/nvidia/TRTorch/issues

So user can have additional context to the problem.

This should fix #511

❓ [Question] How do you use dynamic shape when using fx as ir and the model is not fully lowerable

❓ Question

I have a pytorch model that contains a Pixel Shuffle operation (which is not fully supported) and I would like to convert it to TensorRT, while being able to specify a dynamic shape as input. The "ts" path does not work as there is an issue, the "fx" path has problems too and I am not able to use a splitted model with dynamic shapes.

What you have already tried

The conversion using TorchScript as "ir" is not working (see Issue #1568)
The conversion using torch_tensorrt.fx.compile succeeds when I use a static shape, however there is no way of specifying a dynamic shape
Using a manual approach (that is by manually tracing with acc_tracer, then constructing the TRTInterpreter and finally the TRTModule) fails as there is a non supported operation (a pixel shuffle layer) (Maybe I should open an Issue for this too?)
Using the manual approach with a TRTSplitter is maybe the way to go but I don't know how to specify the dynamic shape constraints in this situation.

The "manual" approach that I mentioned is the one specified in examples/fx/fx2trt_example.py and in the docs.

Here is the code as I have it now. Please note that the branch with the splitter is executed and the result is errors when I execute the trt model with different shapes. If do_split is set to False the conversion fails as nn.PixelShuffle is not supported.

🐛 [Bug] PixelShuffle with dynamic shape error

Bug Description

Trying to convert a model with pixel shuffle and dynamic shape results in many errors, with this message reshape dimension with more than one -1 wildcard.

Converting the model with a static shape works fine.

To Reproduce

Steps to reproduce the error:

Use a model with a nn.PixelShuffle layer
Use a torch_tensorrt.Input with min_shape, opt_shape and max_shape
Try to convert with torch_tensorrt.compile

To reproduce the error use the following code and execute the with dynamic as input:

python pixel_shuffle_bug.py dynamic

Cannot export a torchscript model to TensorRT.

Bug Description

Cannot export a model to TensorRT after successfully transfered to torchscript.

To Reproduce

Steps to reproduce the behavior:

Pull the monai image 1.1.0 from link
Star a docker container with the downloaded image in step 1.
Run the code below.

import torch
import torch_tensorrt
from monai.networks.nets import FlexibleUNet
import monai

if __name__ == "__main__":
    input_size = (1, 3, 480, 736)
    print(monai.__file__)
    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    model = FlexibleUNet(
        in_channels=3, out_channels=2, backbone="efficientnet-b2", is_pad=False
    )

    model.to(device=device)
    model.eval()
    ts_model = torch.jit.script(model)

    inputs = [
        torch_tensorrt.Input(
            min_shape=input_size,
            opt_shape=input_size,
            max_shape=input_size,
        )
    ]
    enabled_precision = {torch.float, torch.half}
    with torch_tensorrt.logging.debug():
        trt_ts_model = torch_tensorrt.compile(
            ts_model, inputs=inputs, enabled_precisions=enabled_precision
        )
    torch.jit.save(trt_ts_model, "model_trt.ts")

Output was:

Releases(v1.3.0)

v1.3.0(Dec 1, 2022)
PyTorch 1.13, CUDA 11.7, TensorRT 8.5, Support for Dynamic Batch for Partially Compiled Modules, Engine Profiling, Experimental Unified Runtime for FX and TorchScript Frontends

Torch-TensorRT 1.3.0 targets PyTorch 1.13, CUDA 11.7, cuDNN 8.5 and TensorRT 8.5. This release focuses on adding support for Dynamic Batch Sizes for partially compiled modules using the TorchScript frontend (this is also supported with the FX frontend). It also introduces a new execution profiling utility to understand the execution of specific engine sub blocks that can be used in conjunction with PyTorch profiling tools to understand the performance of your model post compilation. Finally this release introduces a new experimental unified runtime shared by both the TorchScript and FX frontends. This allows you to start using the FX frontend to generate torch.jit.traceable compiled modules.

Dynamic Batch Sizes for Partially Compiled Modules via the TorchScript Frontend

A long-standing limitation of the partitioning system in the TorchScript function is lack of support for dynamic shapes. In this release we address a major subset of these use cases with support for dynamic batch sizes for modules that will be partially compiled. Usage is the same as the fully compiled workflow where using the torch_tensorrt.Input class, you may define the range of shapes that an input may take during runtime. This is represented as a set of 3 shape sizes: min, max and opt. min and max define the dynamic range of the input Tensor. opt informs TensorRT what size to optimize for provided there are multiple valid kernels available. TensorRT will select kernels that are valid for the full range of input shapes but most efficient at the opt size. In this release, partially compiled module inputs can vary in shape for the highest order dimension.

For example:

min_shape: (1, 3, 128, 128) opt_shape: (8, 3, 128, 128) max_shape: (32, 3, 128, 128)

Is a valid shape range, however:

min_shape: (1, 3, 128, 128) opt_shape: (1, 3, 256, 256) max_shape: (1, 3, 512, 512)

is still not supported.

Engine Profiling [Experimental]

This release introduces a number of profiling tools to measure the performance of TensorRT sub blocks in compiled modules. This can be used in conjunction with PyTorch profiling tools to get a picture of the performance of your model. Profiling for any particular sub block can be enabled by the enabled_profiling() method of any __torch__.classes.tensorrt.Engine attribute, or of any torch_tensorrt.TRTModuleNext. The profiler will dump trace files by default in /tmp, though this path can be customized by either setting the profile_path_prefix of __torch__.classes.tensorrt.Engine or as an argument to torch_tensorrt.TRTModuleNext.enable_precision(profiling_results_dir=""). Traces can be visualized using the Perfetto tool (https://perfetto.dev)

Engine Layer information can also be accessed using get_layer_info which returns a JSON string with the layers / fusions that the engine contains.

Unified Runtime for FX and TorchScript Frontends [Experimental]

In previous versions of Torch-TensorRT, the FX and TorchScript frontends were mostly separate and each had their distinct benefits and limitations. Torch-TensorRT 1.3.0 introduces a new unified runtime to support both FX and TorchScript meaning that you can choose the compilation workflow that makes the most sense for your particular use case, be it pure Python conversion via FX or C++ Torchscript compilation. Both frontends use the same primitives to construct their compiled graphs be it fully compiled or just partially.

Basic Usage

The TorchScript frontend uses the new runtime by default. No additional workflow changes are necessary.

Note: The runtime ABI version was increased to support this feature, as such models compiled with previous versions of Torch-TensorRT will need to be recompiled

For the FX frontend, the new runtime can be chosen but setting use_experimental_fx_rt=True as part of your compile settings to either torch_tensorrt.compile(my_mod, ir="fx", use_experimental_fx_rt=True, explicit_batch_dimension=True) or torch_tensorrt.fx.compile(my_mod, use_experimental_fx_rt=True, explicit_batch_dimension=True)

Note: The new runtime only supports explicit batch dimension

TRTModuleNext

The FX frontend will return a torch.nn.Module containing torch_tensorrt.TRTModuleNext submodules instead of torch_tensorrt.fx.TRTModules. The features of these modules are nearly identical but with a few key improvements.

TRTModuleNext profiling dumps a trace visualizable with Perfetto (see above for more details).

TRTModuleNext modules are torch.jit.trace-able, meaning you can save FX compiled modules as TorchScript for python-less / C++ deployment scenarios. Traced compiled modules have the same deployment instructions as compiled modules produced by the TorchScript frontend.

TRTModuleNext maintains the same serialization workflows TRTModule supports as well (state_dict / extra_state, torch.save/torch.load)

Examples

model_fx = model_fx.cuda() inputs_fx = [i.cuda() for i in inputs_fx] trt_fx_module_f16 = torch_tensorrt.compile( model_fx, ir="fx", inputs=inputs_fx, enabled_precisions={torch.float16}, use_experimental_fx_rt=True, explicit_batch_dimension=True ) # Save model using torch.save torch.save(trt_fx_module_f16, "trt.pt") reload_trt_mod = torch.load("trt.pt") # Trace and save the FX module in TorchScript scripted_fx_module = torch.jit.trace(trt_fx_module_f16, example_inputs=inputs_fx) scripted_fx_module.save("/tmp/scripted_fx_module.ts") scripted_fx_module = torch.jit.load("/tmp/scripted_fx_module.ts")

... #Get a handle for a TRTModuleNext submodule # Extract state dictionary st = trt_mod.state_dict() # Load the state dict into a new module new_trt_mod = TRTModuleNext() new_trt_mod.load_state_dict(st)

Using TRTModuleNext as an arbirary TensorRT engine holder

Using TorchScript you have long been able to embed an arbritrary TensorRT engine from any source in a TorchScript module using torch_tensorrt.ts.embed_engine_in_new_module. Now you can do this at the torch.nn.Module level by directly using TRTModuleNext and access all the benefits enumerated above.

trt_mod = TRTModuleNext( serialized_engine, name="TestModule", input_binding_names=input_names, output_binding_names=output_names, )

The intention is in a future release to have torch_tensorrt.TRTModuleNext replace torch_tensorrt.fx.TRTModule as the default TensorRT Module implementation. Feedback on this class or how it is used, the runtime in general or associated features (profiler, engine inspector) is welcomed.

v1.2.0(Sep 14, 2022)
PyTorch 1.12, Collections based I/O, FX Frontend, torchtrtc custom op support, CMake build system and Community Window Support

Torch-TensorRT 1.2.0 targets PyTorch 1.12, CUDA 11.6, cuDNN 8.4 and TensorRT 8.4. This release focuses on a couple key new APIs to handle function I/O that uses collection types which should enable whole new model classes to be compiled by Torch-TensorRT without source code modification. It also introduces the "FX Frontend", a new frontend for Torch-TensorRT which leverages FX, a high level IR built into PyTorch with extensive Python APIs. For uses cases which do not need to be run outside of Python this may be a strong option to try as it is easily extensible in a familar development enviornment. In Torch-TensorRT 1.2.0, the FX frontend should be considered beta level in stability. torchtrtc has received improvements which target the ability to handle operators outside of the core PyTorch op set. This includes custom operators from libraries such as torchvision and torchtext. Similarlly users can provide custom converters to torchtrtc to extend the compilers support from the command line instead of having to write an application to do so. Finally, Torch-TensorRT introduces community supported Windows and CMake support.

New Dependencies

nvidia-tensorrt

For previous versions of Torch-TensorRT, users had to install TensorRT via system package manager and modify their LD_LIBRARY_PATH in order to set up Torch-TensorRT. Now users should install the TensorRT Python API as part of the installation proceedure. This can be done via the following steps:

pip install nvidia-pyindex pip install nvidia-tensorrt==8.4.3.1 pip install torch-tensorrt==1.2.0 -f https://github.com/pytorch/tensorrt/releases

Installing the TensorRT pip package will allow Torch-TensorRT to automatically load the TensorRT libraries without any modification to enviornment variables. It is also a necessary dependency for the FX Frontend.

torchvision

Some FX frontend converters are designed to target operators from 3rd party libraries like torchvision. As such, you must have torchvision installed in order to use them. However, this dependency is optional for cases where you do not need this support.

Jetson

Starting from this release we will be distributing precompiled binaries of our NGC release branches for aarch64 (as well as x86_64), starting with ngc/22.11. These releases are designed to be paired with NVIDIA distributed builds of PyTorch including the NGC containers and Jetson builds and are equivalent to the prepackaged distribution of Torch-TensorRT that comes in the containers. They represent the state of the master branch at the time of branch cutting so may lag in features by a month or so. These releases will come separately to minor version releases like this one. Therefore going forward, these NGC releases should be the primary release channel used on Jetson (including for building from source).

NOTE: NGC PyTorch builds are not identical to builds you might install through normal channels like pytorch.org. In the past this has caused issues in portability between pytorch.org builds and NGC builds. Therefore we strongly recommend in workflows such as exporting a TorchScript module on an x86 machine and then compiling on Jetson to ensure you are using the NGC container release on x86 for your host machine operations. More information about Jetson support can be found along side the 22.07 release (https://github.com/pytorch/TensorRT/releases/tag/v1.2.0a0.nv22.07)

Collections based I/O [Experimental]

Torch-TensorRT previously has operated under the assumption that nn.Module forward functions can trivially be reduced to the form forward([Tensor]) -> [Tensor]. Typically this implies functions fo the form forward(Tensor, Tensor, ... Tensor) -> (Tensor, Tensor, ..., Tensor). However as model complexity increases, grouping inputs may make it easier to manage many inputs. Therefore, function signatures similar to forward([Tensor], (Tensor, Tensor)) -> [Tensor] or forward((Tensor, Tensor)) -> (Tensor, (Tensor, Tensor)) might be more common. In Torch-TensorRT 1.2.0, more of these kinds of uses cases are supported using the new experimental input_signature compile spec API. This API allows users to group Input specs similar to how they might group the input Tensors they would use to call the original module's forward function. This informs Torch-TensorRT on how to map a Tensor input from its location in a group to the engine and from the engine into its grouping returned back to the user.

To make this concrete consider the following standard case:

class StandardTensorInput(nn.Module): def __init__(self): super(StandardTensorInput, self).__init__() def forward(self, x, y): r = x + y return r x = torch.Tensor([1,2,3]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = StandardTensorInput().eval().to("cuda") trt_module = torch_tensorrt.compile( module, inputs=[ torch_tensorrt.Input(x.shape), torch_tensorrt.Input(y.shape) ], min_block_size=1 ) out = trt_module(x,y) print(out)

Here a user has defined two explicit tensor inputs and used the existing list based API to define the input specs.

With Torch-TensorRT the following use cases are now possible using the new input_signature API:

Tuple based input collection

class TupleInput(nn.Module): def __init__(self): super(TupleInput, self).__init__() def forward(self, z: Tuple[torch.Tensor, torch.Tensor]): r = z[0] + z[1] return r x = torch.Tensor([1,2,3]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = TupleInput().eval().to("cuda") trt_module = torch_tensorrt.compile( module, input_signature=((x, y),), # Note how inputs are grouped with the new API min_block_size=1 ) out = trt_module((x,y)) print(out)

List based input collection

class ListInput(nn.Module): def __init__(self): super(ListInput, self).__init__() def forward(self, z: List[torch.Tensor]): r = z[0] + z[1] return r x = torch.Tensor([1,2,3]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = ListInput().eval().to("cuda") trt_module = torch_tensorrt.compile( module, input_signature=([x,y],), # Again, note how inputs are grouped with the new API min_block_size=1 ) out = trt_module([x,y]) print(out)

Note how the input specs (in this case just example tensors) are provided to the compiler. The input_signature argument expects a Tuple[Union[torch.Tensor, torch_tensorrt.Input, List, Tuple]] grouped in a format representative of how the function would be called. In these cases its just a list or tuple of specs.

More advanced cases are supported as we:

Tuple I/O

class TupleInputOutput(nn.Module): def __init__(self): super(TupleInputOutput, self).__init__() def forward(self, z: Tuple[torch.Tensor, torch.Tensor]): r1 = z[0] + z[1] r2 = z[0] - z[1] r1 = r1 * 10 r = (r1, r2) return r x = torch.Tensor([1,2,3For previous versions of Torch-TensorRT, users had to install TensorRT via ]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = TupleInputOutput() trt_module = torch_tensorrt.compile( module, input_signature=((x,y),), # Again, note how inputs are grouped with the new API min_block_size=1 ) out = trt_module((x,y)) print(out)

List I/O

class ListInputOutput(nn.Module): def __init__(self): super(ListInputOutput, self).__init__() def forward(self, z: List[torch.Tensor]): r1 = z[0] + z[1] r2 = z[0] - z[1] r = [r1, r2] return r x = torch.Tensor([1,2,3]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = ListInputOutput() trt_module = torch_tensorrt.compile( module, input_signature=([x,y],), # Again, note how inputs are grouped with the new API min_block_size=1 ) out = trt_module((x,y)) print(out)

Multple Groups of Mixed Types

class MultiGroupIO(nn.Module): def __init__(self): super(MultiGroupIO, self).__init__() def forward(self, z: List[torch.Tensor], a: Tuple[torch.Tensor, torch.Tensor]): r1 = z[0] + z[1] r2 = a[0] + a[1] r3 = r1 - r2 r4 = [r1, r2] return (r3, r4) x = torch.Tensor([1,2,3]).to("cuda") y = torch.Tensor([4,5,6]).to("cuda") module = MultiGroupIO().eval.to("cuda") trt_module = torch_tensorrt.compile( module, input_signature=([x,y],(x,y)), # Again, note how inputs are grouped with the new API min_block_size=1 ) out = trt_module([x,y],(x,y)) print(out)

These features are also supported in C++ as well:

torch::jit::Module mod; try { // Deserialize the ScriptModule from a file using torch::jit::load(). mod = torch::jit::load(path); } catch (const c10::Error& e) { std::cerr << "error loading the model\n"; } mod.eval(); mod.to(torch::kCUDA); std::vector<torch::jit::IValue> inputs_; for (auto in : inputs) { inputs_.push_back(torch::jit::IValue(in.clone())); } std::vector<torch::jit::IValue> complex_inputs; auto input_list = c10::impl::GenericList(c10::TensorType::get()); input_list.push_back(inputs_[0]); input_list.push_back(inputs_[0]); torch::jit::IValue input_list_ivalue = torch::jit::IValue(input_list); complex_inputs.push_back(input_list_ivalue); auto input_shape = torch_tensorrt::Input(in0.sizes(), torch_tensorrt::DataType::kHalf); auto input_shape_ivalue = torch::jit::IValue(std::move(c10::make_intrusive<torch_tensorrt::Input>(input_shape))); c10::TypePtr elementType = input_shape_ivalue.type(); auto list = c10::impl::GenericList(elementType); list.push_back(input_shape_ivalue); list.push_back(input_shape_ivalue); torch::jit::IValue complex_input_shape(list); std::tuple<torch::jit::IValue> input_tuple2(complex_input_shape); torch::jit::IValue complex_input_shape2(input_tuple2); auto compile_settings = torch_tensorrt::ts::CompileSpec(complex_input_shape2); compile_settings.min_block_size = 1; compile_settings.enabled_precisions = {torch::kHalf}; // // Compile module auto trt_mod = torch_tensorrt::ts::compile(mod, compile_settings); auto trt_out = trt_mod.forward(complex_inputs);

Currently this feature should be considered experimental, APIs may be subject to change or folded into existing APIs. There are also limitations introduced by using this feature including the following:

Not all collection types are supported (e.g. Dict, namedtuple)

Not being able to require_full_compilation while using this feature

Certain operators are required to run in PyTorch throughout the graph which may impact performance

The maximum depth of collections nesting is limited.
These limitations will be addressed in subsequent versions.

Adding FX frontend to Torch-TensorRT [Beta]

This release includes the FX as one of its supported IRs to convert torch models to TensorRT through the new FX frontend. At a high level, this path transforms the model into or consumes an FX graph and similar to the TorchScript frontend converts the graph to TensorRT through the use of a library of converters. The key difference is that it is implemented purely in Python. The role of this FX frontend is to supplement the TS lowering path and to provide users better ease of use and easier extensibility in use cases where removing Python as a dependency is not strictly necessary. Detailed user instructions can be find in the document. The FX path examples are located under //examples/fx The FX path unit tests are located under //py/torch_tensorrt/fx/tests

Custom operators and converters in Torch-TensorRT

While both the C++ API and Python API provide systems to include and convert custom operators in your model (for instance those implemented in torchvision) torchtrtc has been limited to the core opset. In Torch-TensorRT 1.2.0 two new flags have been added to torchtrtc.

--custom-torch-ops (repeatable) Shared object/DLL containing custom torch operators --custom-converters (repeatable) Shared object/DLL containing custom converters

These arguments accept paths to .so or DLL files which define custom operators for PyTorch or custom converters for Torch-TensorRT. These files will get DL_OPEN'd at runtime to extend the op and converter libraries.

For example:

torchtrtc tests/modules/ssd_traced.jit.pt ssd_trt.ts --custom-torch-ops=<path to custom library .so file> --custom-converters=<path to custom library .so file> "[(1,3,300,300); (1,3,512,512); (1, 3, 1024, 1024)]@fp16%contiguous" -p f16

Community CMake and Windows support

Thanks to the great work of @gcuendet and others, CMake and consequentially Windows support has been added to the project! Users on Linux and Windows can now build the C++ API using this system and using torch_tensorrt_runtime.dll add support for executing Torch-TensorRT programs on Windows in both Python and C++. Detailed information on how to use this build system can be found here: https://pytorch.org/TensorRT/getting_started/installation.html

Bazel will continue to be the primary build system for the project and all testing and distributed builds will be built and run with Bazel (including future official Windows support) so users should consider this still the canonical version of Torch-TensorRT. However we aim to ensure as best as we can that the CMake system will be able to build the project properly including on Windows. Contributions to continue to grow the support for this build system and Windows as a platform are definitely welcomed.

v1.1.1(Jul 16, 2022)
Adding support for Torch-TensorRT on Jetpack 5.0 Developer Preview

Torch-TensorRT 1.1.1 is a patch release for Torch-TensorRT 1.1 that targets PyTorch 1.11, CUDA 11.4/11.3, TensorRT 8.4 EA/8.2 and cuDNN 8.3/8.2 intended to add support for Torch-TensorRT on Jetson / Jetpack 5.0 DP. As this release is primarily targeted at adding support for Jetpack 5.0DP for the 1.1 feature set we will not be distributing pre-compiled binaries for this release so as not to break compatibility with the current stack for existing users who install directly from GitHub. Please follow the instructions for installation on Jetson in the documentation to install this release: https://pytorch.org/TensorRT/tutorials/installation.html#compiling-from-source

Known Limitations

We have observed in testing, higher than normal numerical instability on Jetpack 5.0 DP. These issues are not observed on x86_64 based platforms. This numerical instability has not been found to decrease model accuracy in our test suite.

Support for PyTorch 1.11, Various Bug Fixes, Partial aten::Int support, New Debugging Tools, Removing Max Batch Size

Torch-TensorRT 1.1.0 targets PyTorch 1.11, CUDA 11.3, cuDNN 8.2 and TensorRT 8.2. Due to recent JetPack upgrades, this release does not support Jetson (Jetpack 5.0DP or otherwise). Jetpack 5.0DP support will arrive in a mid-cycle release (Torch-TensorRT 1.1.x) along with support for TensorRT 8.4. 1.1.0 also drops support for Python 3.6 as it has reached end of life. Following 1.0.0, this release is focused on stabilizing and improving the core of Torch-TensorRT. Many improvements have been made to the partitioning system addressing limitation many users hit while trying to partially compile PyTorch modules. Torch-TensorRT 1.1.0 also addresses a long standing issue with aten::Int operators (albeit) partially. Now certain common patterns which use aten::Int can be handled by the compiler without resorting to partial compilation. Most notably, this means that models like BERT can be run end to end with Torch-TensorRT, resulting in significant performance gains.

New Debugging Tools

With this release we are introducing new syntax sugar that can be used to more easily debug Torch-TensorRT compilation and execution through the use of context managers. For example, in Torch-TensorRT 1.0.0 this may be a common pattern to turn on then turn off debug info:

import torch_tensorrt ... torch_tensorrt.logging.set_reportable_log_level(torch_tensorrt.logging.Level.Debug) trt_module = torch_tensorrt.compile(my_module, ...) torch_tensorrt.logging.set_reportable_log_level(torch_tensorrt.logging.Level.Warning) results = trt_module(input_tensors)

With Torch-TensorRT 1.1.0, this now can be done with the following code:

import torch_tensorrt ... with torch_tensorrt.logging.debug(): trt_module = torch_tensorrt.compile(my_module,...) results = trt_module(input_tensors)

You can also use this API to debug the Torch-TensorRT runtime as well:

import torch_tensorrt torch_tensorrt.logging.set_reportable_log_level(torch_tensorrt.logging.Level.Error) ... trt_module = torch_tensorrt.compile(my_module,...) with torch_tensorrt.logging.warnings(): results = trt_module(input_tensors)

The following levels are available:

# Only internal TensorRT failures will be logged with torch_tensorrt.logging.internal_errors(): # Internal TensorRT failures + Torch-TensorRT errors will be logged with torch_tensorrt.logging.errors(): # All Errors plus warnings will be logged with torch_tensorrt.logging.warnings(): # First verbosity level, information about major steps occurring during compilation and execution with torch_tensorrt.logging.info(): # Second verbosity level, each step is logged + information about compiler state will be outputted with torch_tensorrt.logging.debug(): # Third verbosity level, all above information + intermediate transformations of the graph during lowering with torch_tensorrt.logging.graphs():

Removing Max Batch Size, Strict Types

In this release we are removing the max_batch_size and strict_types settings. These settings directly corresponded to the TensorRT settings, however were not always respected which often lead to confusion. Therefore we thought it best to disable these features as deterministic behavior could not be ensured.

Porting forward from max_batch_size, strict_types:

max_batch_size: The first dim in shapes provided to Torch-TensorRT are considered batch dimensions, therefore instead of setting max_batch_size, you can just use the Input objects directly

strict_types: A replacement with more deterministic behavior will come with an upcoming TensorRT release.

BREAKING CHANGES

This commit removes the strict types and max_batch_size apis. We are doing this because the functionality of these APIs in TRT is convoluted and likely to be ignored during building. A replacement for strict types with actual guarantees will be added at a later date.

This is a minor change but may cause scripts using torchtrtc to fail. We are renaming enabled-precisions to enable-precision since it makes more sense as the argument can be repeated

This PR removes --max-batch-size from the CLI as it has no real functional effect

New Name!, Support for PyTorch 1.10, CUDA 11.3, New Packaging and Distribution Options, Stabilized APIs, Stabilized Partial Compilation, Adjusted Default Behavior, Usability Improvements, New Converters, Bug Fixes

This is the first stable release of Torch-TensorRT targeting PyTorch 1.10, CUDA 11.3 (on x86_64, CUDA 10.2 on aarch64), cuDNN 8.2 and TensorRT 8.0 with backwards compatible source for TensorRT 7.1. On aarch64 TRTorch targets Jetpack 4.6 primarily with backwards compatible source for Jetpack 4.5. This version also removes deprecated APIs such as InputRange and op_precision

New Name

TRTorch is now Torch-TensorRT! TRTorch started out as a small experimental project compiling TorchScript to TensorRT almost two years ago and now as we are hitting v1.0.0 with APIs and major features stabilizing we felt that the name of the project should reflect the ecosystem of tools it is joining with this release, namely TF-TRT (https://blog.tensorflow.org/2021/01/leveraging-tensorflow-tensorrt-integration.html) and MXNet-TensorRT(https://mxnet.apache.org/versions/1.8.0/api/python/docs/tutorials/performance/backend/tensorrt/tensorrt). Since we were already significantly changing APIs with this release to reflect what we learned over the last two years of using TRTorch, we felt this is was the right time to change the name as well.

The overall process to port forward from TRTorch is as follows:

Python

The library has been renamed from trtorch to torch_tensorrt

Components that used to all live under the trtorch namespace have now been separated. IR agnostic components: torch_tensorrt.Input, torch_tensorrt.Device, torch_tensorrt.ptq, torch_tensorrt.logging will continue to live under the top level namespace. IR specific components like torch_tensorrt.ts.compile, torch_tensorrt.ts.convert_method_to_trt_engine, torch_tensorrt.ts.TensorRTCompileSpec will live in a TorchScript specific namespace. This gives us space to explore the other IRs that might be relevant to the project in the future. In the place of the old top level compile and convert_method_to_engine are new ones which will call the IR specific versions based on what is provided to them. This also means that you can now provide a raw torch.nn.Module to torch_tensorrt.compile and Torch-TensorRT will handle the TorchScripting step for you. For the most part the sole change that will be needed to change over namespaces is to exchange trtorch to torch_tensorrt

C++

Similar to Python the namespaces in C++ have changed from trtorch to torch_tensorrt and components specific to the IR like compile, convert_method_to_trt_engine and CompileSpec are in a torchscript namespace, while agnostic components are at the top level. Namespace aliases for torch_tensorrt -> torchtrt and torchscript -> ts are included. Again the port forward process for namespaces should be a find and replace. Finally the libraries libtrtorch.so, libtrtorchrt.so and libtrtorch_plugins.so have been renamed to libtorchtrt.so, libtorchtrt_runtime.so and libtorchtrt_plugins.so respectively.

CLI:

trtorch has been renamed to torchtrtc

New Distribution Options and Packaging

Starting with nvcr.io/nvidia/pytorch:21.11, Torch-TensorRT will be distributed as part of the container (https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch). The version of Torch-TensorRT in container will be the state of the master at the time of building. Torch-TensorRT will be validated to run correctly with the version of PyTorch, CUDA, cuDNN and TensorRT in the container. This will serve as the easiest way to have a full validated PyTorch end to end training to inference stack and serves as a great starting point for building DL applications.

Also as part of Torch-TensorRT we are now starting to distribute the full C++ package within the wheel files for the Python packages. By installing the wheel you now get the Python API, the C++ libraries + headers and the CLI binary. This is going to be the easiest way to install Torch-TensorRT on your stack. After installing with pip

pip3 install torch-tensorrt -f https://github.com/NVIDIA/Torch-TensorRT/releases

You can add the following to your PATH to set up the CLI

PATH=$PATH:<PATH TO TORCHTRT PYTHON PACKAGE>/bin

Stabilized APIs

Python

Many of the APIs have change slighly in this release to be more self consistent and more usable. These changes begin with the Python API for which compile, convert_method_to_trt_engine and TensorRTCompileSpec now instead of dictionaries use kwargs. As features many features came out of beta and experimental stability the necessity to have multiple levels of nesting in settings has decreased, therefore kwargs make much more sense. You can simply port forward to the new APIs by unwrapping your existing compile_spec dict in the arguments to compile or similar functions.

Example:

compile_settings = { "inputs": [torch_tensorrt.Input( min_shape=[1, 3, 224, 224], opt_shape=[1, 3, 512, 512], max_shape=[1, 3, 1024, 1024], # For static size shape=[1, 3, 224, 224] dtype=torch.half, # Datatype of input tensor. Allowed options torch.(float|half|int8|int32|bool) )], "enabled_precisions": {torch.half}, # Run with FP16 } trt_ts_module = torch_tensorrt.compile(torch_script_module, **compile_settings)

This release also introduces support for providing tensors as examples to Torch-TensorRT. In place of a torch_tensorrt.Input in the list of inputs you can pass a Tensor. This can only be used to set a static input size. There are also some things to be aware of which will be discussed later in the release notes.

Now that Torch-TensorRT separates components specific to particular IRs to their own namespaces, there is now a replacement for the old compile and convert_method_to_trt_engine functions on the top level. These functions take any PyTorch generated format including torch.nn.Modules and decides the best way to compile it down to TensorRT. In v1.0.0 this means to go through TorchScript and return a Torch.jit.ScriptModule. You can specify the IR to try using the ir arg for these functions.

Due to partial compilation becoming stable in v1.0.0, there are now four new fields which replace the old torch_fallback struct.

old:

complie_spec = { "torch_fallback": { "enabled": True, # Turn on or turn off falling back to PyTorch if operations are not supported in TensorRT "force_fallback_ops": [ "aten::max_pool2d" # List of specific ops to require running in PyTorch ], "force_fallback_modules": [ "mypymod.mytorchmod" # List of specific torch modules to require running in PyTorch ], "min_block_size": 3 # Minimum number of ops an engine must incapsulate to be run in TensorRT } }

new:

torch_tensorrt.compile(..., require_full_compilation=False, min_block_size=3, torch_executed_ops=[ "aten::max_pool2d" ], torch_executed_modules=["mypymod.mytorchmod"])

C++

The changes for the C++ API other than the reorganization and renaming of the namespaces, mostly serve to make Torch-TensorRT consistent between Python and C++ namely by renaming trtorch::CompileGraph to torch_tensorrt::ts::compile and trtorch::ConvertGraphToTRTEngine to torch_tensorrt::ts::convert_method_to_trt_engine. Beyond that similar to Python, the partial compilation struct TorchFallback has been removed and replaced by four fields in torch_tensorrt::ts::CompileSpec

old:

/** * @brief A struct to hold fallback info */ struct TRTORCH_API TorchFallback { /// enable the automatic fallback feature bool enabled = false; /// minimum consecutive operation number that needs to be satisfied to convert to TensorRT uint64_t min_block_size = 1; /// A list of names of operations that will explicitly run in PyTorch std::vector<std::string> forced_fallback_ops; /// A list of names of modules that will explicitly run in PyTorch std::vector<std::string> forced_fallback_modules; /** * @brief Construct a default Torch Fallback object, fallback will be off */ TorchFallback() = default; /** * @brief Construct from a bool */ TorchFallback(bool enabled) : enabled(enabled) {} /** * @brief Constructor for setting min_block_size */ TorchFallback(bool enabled, uint64_t min_size) : enabled(enabled), min_block_size(min_size) {} };

new:

/** * Require the full module be compiled to TensorRT instead of potentially running unsupported operations in PyTorch */ bool require_full_compilation = false; /** * Minimum number of contiguous supported operators to compile a subgraph to TensorRT */ uint64_t min_block_size = 3; /** * List of aten operators that must be run in PyTorch. An error will be thrown if this list is not empty but * ``require_full_compilation`` is True */ std::vector<std::string> torch_executed_ops; /** * List of modules that must be run in PyTorch. An error will be thrown if this list is not empty but * ``require_full_compilation`` is True */ std::vector<std::string> torch_executed_modules;

CLI

Similarly these partial compilation fields have been renamed in torchtrtc:

--require-full-compilation Require that the model should be fully compiled to TensorRT or throw an error --teo=[torch-executed-ops...], --torch-executed-ops=[torch-executed-ops...] (Repeatable) Operator in the graph that should always be run in PyTorch for execution (partial compilation must be enabled) --tem=[torch-executed-mods...], --torch-executed-mods=[torch-executed-mods...] (Repeatable) Module that should always be run in Pytorch for execution (partial compilation must be enabled) --mbs=consecutive_ops, --min-block-size=consecutive_ops Minimum number of contiguous TensorRT supported ops to compile a subgraph to TensorRT

Going forward breaking changes to the API the sort of magnitude seen in this release will be accompanied by a major version bump.

Stabilized Partial Compilation

Partial compilation should be considered stable for static input shape and is now enabled by default. In the case of dynamic shape, set require_full_compilation to True.

Adjusted Defaults

Input Types

Default behavior of Torch-TensorRT has shifted slightly. The most important of these changes is the changes to inferred input type. In prior versions the expected input type for a Tensor barring it being set explicitly was based on the op_precision. With that field being removed in this release and being replaced with enabled_precisions introduced in v0.4.0 this sort of behavior no longer makes sense. Therefore now Torch-TensorRT follows these rules to determine Input type for a Tensor.

If no dtype is specified for an Input, Torch-TensorRT will determine the input type by inspecting the uses of this Input. It will trace the lifetime of this tensor to the first tensor operation using weights stored in the provided module. The type of the weights is the inferred type of the Input using the rule that PyTorch requires like types for Tensor operations. The goal with this behavior is to maintain the concept that Torch-TensorRT modules should feel no different than normal PyTorch modules. Therefore you can expect | Weight Type of Model | Expected Input Type For Tensor | |--------------------------------|--------------------------------------------| | FP32 | FP32 | | FP16 | FP16 | | Quantization Workflows | FP32 | | Unknown / Ambiguous | FP32 w/ Warning |

Users can override this behavior to set the Input type to whatever they wish using the dtype field of torch_tensorrt.Input. Torch-TensorRT will always respect the user setting but may throw a warning stating that the model provided expects a different input type. This is mainly to notify you that just dropping the compiled module in place of the raw torch.nn.Module might throw errors and casting before inference might be necessary.

With Torch-TensorRT v1.0.0 you can provide example torch Tensors to set the input shape. However, this not only sets the input shape but also the input dtype and tensor format as well. So if you provide a half precision 1x3x32x32 contiguous tensor the expected input would be Input(shape=(1, 3, 32, 32), dtype=dtype.half, format=TensorFormat.contiguous). This is subject to the behavior in 2.

Workspace Size

Now by default the workspace size is set to 1GB for all GPUs Pascal based and newer (SM capability 6 or above). Maxwell and older cards including Jetson Nano have a workspace of 256MB by default. This value is user settable.

This changes the API for compile settings from a dictionary of settings to a set of kwargs for the various compilation functions. This will break existing code. However there is simple guidance to port forward your code:

Given a dict of valid TRTorch CompileSpec settings

spec = { "inputs": ... ... }

You can use this same dict with the new APIs by changing your code from:

trtorch.compile(mod, spec)

to:

trtorch.compile(mod, **spec)

which will unpack the dictionary as arguments to the function

This commit changes the default behavior of the compiler where if the user does not specify an input data type explicity instead of using the enabled precision, now the compiler will inspect the model provided to infer the data type for the input that will not cause an error if the model was run in torch. In practice this means

If the weights are in FP32 for the first tensor calculation then default input type is FP32

If the weights are in FP16 for the first tensor calculation then default input type is FP16

etc.

If the data type cannot be determined the compiler will default to FP32.

This calculation is done per input tensor so if one input is inferred to use FP32 and another INT32 then the expected types will be the same (FP32, INT32)

As was the same before if the user defines the data type explicitly or provides an example tensor the data type specified there will be respected

Bug Fixes for Module Ignorelist for Partial Compilation, trtorch.Device, Version updates for PyTorch, TensorRT, cuDNN

Target Platform Changes

This is the first patch of TRTorch v0.4. It now targets by default PyTorch 1.9.1, TensorRT 8.0.3.4 and cuDNN 8.2.4.15 and CUDA 11.1. Older versions of PyTorch, TensorRT, cuDNN are still supported in the same manner as TRTorch v0.4.0

Module Ignorelist for Partial Compilation

There was an issue with the pass marking modules to be ignored during compilation where it unsafely assumed that methods are named forward all the way down the module tree. While this was fine for 1.8.0, with PyTorch 1.9.0, the TorchScript codegen changed slightly to sometimes use methods of other names for modules which reduce trivially to a functional api. This fix now will identify method calls as the recursion point and then use those method calls to select modules to recurse on. It will also check to verify existence of these modules and methods before recursing. Finally this pass was run by default even if the ignore list was empty causing issues for users not using the feature. Therefore this pass is now disabled unless explicitly enabled

trtorch.Device

Some of the constructors for trtorch.Device would not work or incorrectly configure the device. This patch will fix those issues.

Dependencies

- Bazel 4.0.0 - LibTorch 1.9.1 - CUDA 11.1 (on x86_64, by default, newer CUDA 11 supported with compatible PyTorch Build), 10.2 (on aarch64) - cuDNN 8.2.3.4 - TensorRT 8.0.3.4

0.4.1 (2021-10-06)

TRTorch v0.4.0

Support for PyTorch 1.9, TensorRT 8.0. Introducing INT8 Execution for QAT models, Module Based Partial Compilation, Auto Device Configuration, Input Class, Usability Improvements, New Converters, Bug Fixes

Target Platform Changes

This is the fourth beta release of TRTorch, targeting PyTorch 1.9, CUDA 11.1 (on x86_64, CUDA 10.2 on aarch64), cuDNN 8.2 and TensorRT 8.0 with backwards compatible source for TensorRT 7.1. On aarch64 TRTorch targets Jetpack 4.6 primarily with backwards compatibile source for Jetpack 4.5. When building on Jetson, the flag --platforms //toolchains:jetpack_4.x must be now be provided for C++ compilation to select the correct dependency paths. For python by default it is assumed the Jetpack version is 4.6. To override this add the --jetpack-version 4.5 flag when building.

TensorRT 8.0

This release adds support for compiling models trained with Quantization aware training (QAT) allowing users using the TensorRT PyTorch Quantization Toolkit (https://github.com/NVIDIA/TensorRT/tree/master/tools/pytorch-quantization) to compile their models using TRTorch. For more information and a tutorial, refer to https://www.github.com/NVIDIA/TRTorch/tree/v0.4.0/examples/int8/qat. It also adds support for sparsity via the sparse_weights flag in the compile spec. This allows TensorRT to utilize specialized hardware in Ampere GPUs to minimize unnecessary computation and therefore increase computational efficiency.

Partial Compilation

In v0.4.0 the partial compilation feature of TRTorch can now be considered beta level stability. New in this release is the ability to specify entire PyTorch modules to run in PyTorch explicitly as part of partial compilation. This should let users isolate troublesome code easily when compiling. Again, feedback on this feature is greatly appreciated.

Automatic Device Configuration at Runtime

v0.4.0 also changes the "ABI" of TRTorch to now include information about the target device for the program. Programs compiled with v0.4.0 will look for and select the most compatible available device. The rules used are: Any valid device option must have the same SM capability as the device building the engine. From there, TRTorch prefers the same device (e.g. Built on A100 so A100 is better than A30) and finally prefers the same device ID. Users will be warned if this selected device is not the current active device in the course of execution as overhead may be incurred in transferring input tensors from the current device to the target device. Users can then modify their code to avoid this. Due to this ABI change, existing compiled TRTorch programs are incompatible with the TRTorch v0.4.0 runtime. From v0.4.0 onwards an internal ABI version will check program compatibility. This ABI version is only incremented with breaking changes to the ABI.

API Changes (Input, enabled_precisions, Device)

TRTorch v0.4.0 changes the API for specifying Input shapes and data types to provide users more control over configuration. The new API makes use of the class trtorch.Input which lets users set the shape (or shape range) as well as memory layout and expected data type. These input specs are set in the input field of the CompileSpec.

"inputs": [ trtorch.Input((1, 3, 224, 224)), # Static input shape for input #1 trtorch.Input( min_shape=(1, 224, 224, 3), opt_shape=(1, 512, 512, 3), max_shape=(1, 1024, 1024, 3), dtype=torch.int32, format=torch.channel_last, ) # Dynamic input shape for input #2, input type int and channel last format ],

The legacy input_shapes field and associated usage with lists of tuples/InputRanges should now be considered deprecated. They remain usable in v0.4.0 but will be removed in the next release. Similarly, the compile spec field op_precision is now also deprecated in favor of enabled_precisions. enabled_precisions is a set containing the data types that kernels will be allowed to use. Whereas setting op_precision = torch.int8 would implicitly enable FP32 and FP16 kernels as well, now enabled_precisions should be set as {torch.float32, torch.float16, torch.int8} to do the same. In order to maintain similar behavior to normal PyTorch, if FP16 is the lowest precision enabled but no explicit data type is set for the inputs to the model, the expectation will be that inputs will be in FP16 . For other cases (FP32, INT8) FP32 is the default, similar to PyTorch and previous versions of TRTorch. Finally in the Python API, a class trtorch.Device has been added. While users can continue to use torch.Device or other torch APIs, trtorch.Device allows for better control for the specific use cases of compiling with TRTorch (e.g. setting DLA core and GPU fallback). This class is very similar to the C++ version with a couple additions of syntactic sugar to make the class easier and more familiar to use:

trtorch.Device("dla:0", allow_gpu_fallback=False) #Set device as DLA Core 0 (implicitly sets the GPU managing DLA cores as the GPU and sets fallback to false)

trtorch.Device can be used instead of a dictionary in the compile spec if desired.

trtorchc has been updated to reflect these API changes. Users can set the shape, dtype and format of inputs from the command line using the following format "[(MIN_N,..,MIN_C,MIN_H,MIN_W);(OPT_N,..,OPT_C,OPT_H,OPT_W);(MAX_N,..,MAX_C,MAX_H,MAX_W)]@DTYPE%FORMAT" e.g. (3, 3, 32,32)@f16%NHWC. -p is now a repeatable flag to enable multiple precisions. Also added are repeatable flags --ffm and --ffo to mark specific modules and operators for running in PyTorch respectively. To use these two options, --allow-torch-fallback should be set. Options for embedding serialized engines (--embed-engine) and sparsity (--sparse-weights) added as well.

Usability

Finally, TRTorch v0.4.0 also now includes the ability to provide backtraces for locations in your model which TRTorch does not support. This can help in identifying locations in the model that might need to change for TRTorch support or modules which should run fully in PyTorch via partial compilation.

BREAKING CHANGES

This commit cleans up the WIP CudaDevice class, simplifying implementation and formalizing the seralized format for CUDA devices.

It also implements ABI Versioning. The first entry in the serialized format of a TRTEngine now records the ABI that the engine was compiled with, defining expected compatibility with the TRTorch runtime. If the ABI version does not match, the runtime will error out asking to recompile the program.

ABI version is a monotonically increasing integer and should be incremented everytime the serialization format changes in some way.

This commit cleans up the CudaDevice class, implementing a number of constructors to replace the various utility functions that populate the struct. Descriptive utility functions remain but solely call the relevant constructor.

This commit introduces the next iteration of the Python TRTorch API. Starting in TRTorch v0.5.0 support for the "input_shapes" and "op_precision" compile spec keys will be removed. Users should port forward to using the "inputs" key which expects a list of trtorch.Input objects and the "enabled_precisions" key which expects a set of data type specifying enums.

TRTorch v0.3.0

Support for PyTorch 1.8.x (by default 1.8.1), Introducing Plugin Library, PTQ from Python, Arbitrary TRT engine embedding, Preview Release of Partial Compilation, New Converters, Bug Fixes

This is the third beta release of TRTorch, targeting PyTorch 1.8.x, CUDA 11.1 (on x86_64), TensorRT 7.2, cuDNN 8. TRTorch 0.3.0 binary releases target PyTorch 1.8.1 specifically, these builds are not compatible with 1.8.0, though the source code remains compatible with any PyTorch 1.8.x version. On aarch64 TRTorch targets JetPack 4.5.x. This release introduces libtrtorch_plugins.so. This library is a portable distribution of all TensorRT plugins used in TRTorch. The intended usecase is to support TRTorch programs that utilize TensorRT plugins deployed on systems with only the runtime library available or in the case that TRTorch was used to create a TensorRT engine to be run outside the TRTorch runtime, which makes uses of TRTorch plugins. An example on how to use this library can be found here: https://www.github.com/NVIDIA/TRTorch/tree/v0.3.0/examples/sample_rt_app. TRTorch 0.3.0 also now allows users to repurpose PyTorch Dataloaders to do post training quantization in Python similar to the workflow supported in C++ currently. It also introduces a new API to wrap arbitrary TensorRT engines in a PyTorch Module wrapper, making the serializable by torch.jit.save and completely compatible with other PyTorch modules. Finally, TRTorch 0.3.0 also includes a preview of the new partial compilation capability of the TRTorch compiler. With this feature, users can now instruct TRTorch to keep operations that are not supported but TRTorch/TensorRT in PyTorch. Partial compilation should be considered alpha stability and we are seeking feedback on bugs, pain points and feature requests surrounding using this feature.

Dependencies:

- Bazel 4.0.0 - LibTorch 1.8.1 (on x86_64), 1.8.0 (on aarch64) - CUDA 11.1 (on x86_64, by default , newer CUDA 11 supported with compatible PyTorch Build), 10.2 (on aarch64) - cuDNN 8.1.1 - TensorRT 7.2.3.4

BREAKING CHANGES

PyTorch version has been bumped to 1.8.0 Default CUDA version is CUDA 11.1 TensorRT version is TensorRT 7.2.3.4 cuDNN version is now cuDNN 8.1

Signed-off-by: Naren Dasan [email protected] Signed-off-by: Naren Dasan [email protected]

Due to issues with compatability between PyTorch 1.8.0 and 1.8.1 in the Torch Python API, TRTorch 0.3.0 compiled for 1.8.0 does not work with PyTorch 1.8.1 and will show an error about use_input_stats. If you see this error make sure the version of libtorch you are compiling with is PyTorch 1.8.1

TRTorch 0.3.0 will target PyTorch 1.8.1. There is no backwards compatability with 1.8.0. If you need this specific version compile from source with the dependencies in WORKSPACE changed

v0.2.0(Feb 26, 2021)
TRTorch v0.2.0

Support for PyTorch 1.7.x, Multi Device APIs, Runtime Library, New Converters, Bug Fixes

This is the second beta release of TRTorch, targeting PyTorch 1.7.x, CUDA 11.0 (on x86_64), TensorRT 7.2 and cuDNN 8. TRTorch 0.2.0 for aarch64 targets JetPack 4.5.x. It updates the to_backend integration for PyTorch to reflect changes in the PyTorch API. A new API has been added to disable the newly introduced TF32 data format used on Ampere as TF32 is now the default FP32 format used in TRTorch. APIs have been solidified for runtime configuration of the active CUDA device to let users choose what device a program is deserialized on. This API will continue to change as we further define the serialization format and work with the PyTorch team to make runtime device configuration more ergonomic. You can follow this work here: https://github.com/NVIDIA/TRTorch/discussions/311. This PR also formalizes DLA support in TRTorch, adding APIs and capabilities to target DLA on Jetson and DRIVE platforms. v0.2.0 also includes a new shared library libtrtorchrt.so. This library only contains the runtime components of TRTorch and is suitable for use in situations where device footprint is extremely limited. libtrtorch.so can be linked to C++ applications and loaded into Python scripts and will load all necessary trtorch runtime components into the torch runtime allowing users to run TRTorch applications without the full compiler. v0.2.0 also adds support for Python 3.9.

Dependencies:

- Bazel 4.0.0 - Libtorch 1.7.1 (on x86_64), 1.7.0 (on aarch64) - CUDA 11.0 (by default, newer CUDA 11 supported with compatible PyTorch build) - cuDNN 8.0.5 - TensorRT 7.2.2

v0.1.0(Oct 23, 2020)
TRTorch v0.1.0

Direct PyTorch integration via backend API, support for Ampere, support for simple branch and loop cases

This is the first "beta" release of TRTorch, introducing direct integration into PyTorch via the new Backend API. This release also contains an NGC based Dockerfile for users looking to use TRTorch on Ampere, using NGC's patched version of PyTorch. Note that compiled programs from older versions of TRTorch are not compatible with the TRTorch 0.1.0 runtime due to an ABI change. There are now example Jupyter notebooks which demonstrate various features of the compiler included in the documentation.

TRTorch v0.0.3

aarch64 toolchain, Revised PTQ API, PyTorch 1.5.1, support for cuDNN 8.0, TensorRT 7.1 (with compatible PyTorch build)

This is the thrid alpha release of TRTorch. It bumps the target PyTorch version to 1.5.1 and introduces support for cuDNN 8.0 and TensorRT 7.1, however this is only supported in cases where PyTorch has been compiled with the same cuDNN version. This release also introduces formal support for aarch64, however pre-compiled binaries will not be available until we can deliver python packages for aarch64 for all supported version of python. Note some idiosyncrasies when it comes to working with PyTorch on aarch64, if you are using PyTorch compiled by NVIDIA for aarch64 the ABI version is CXX11 instead of the pre CXX11 ABI found on PyTorch on x86_64. When compiling the Python API for TRTorch add the --use-cxx11-abi flag to the command and do not use the --config=pre-cxx11-abi flag when building the C++ library (more instructions on native aarch64 compilation in the documentation). This release also introduces a breaking change to the C++ API where now in order to use logging or ptq APIs a separate header file must be included. Look at the implementation of trtorchc or ptq for example usage.

Dependencies:

Bazel 3.3.1

Libtorch 1.5.1

CUDA 10.2

cuDNN 7.6.5 (by default, cuDNN 8 supported with compatable PyTorch build)

BREAKING CHANGES

Bazel version is now locked to Bazel 3.3.1 and will be bumped manually from now on. Builds will fail on all other versions since now bazel will check the version before it compiles.

Documentation on how to install bazel is added as well to support aarch64 until bazel releases binaries for the platform (which is soon)

Signed-off-by: Naren Dasan [email protected] Signed-off-by: Naren Dasan [email protected]

To use ptq you now need to include trtorch/ptq.h in addition to trtorch/trtorch.h, similarly for logging commands you need to include trtorch/logging.h
