Overview

NuPIC Core

This repository contains the C++ source code for the Numenta Platform for Intelligent Computing (NuPIC). It will eventually contain all algorithms for NuPIC, but is currently in a transition period. For details on building NuPIC within the python environment, please see http://github.com/numenta/nupic.

Installing from a Release

You can install the nupic.bindings Python package from PyPI:

pip install nupic.bindings

Optionally include --user or other flags to determine where the package is installed.

Note: On Linux this will do a source installation and will require that the prerequisites specified below are installed.

Building from Source

Important notes:

$NUPIC_CORE is the current location of the repository that you downloaded from GitHub.
Platform specific Readme.md text files exist in some external/ subdirectories
See the main wiki for more build notes

Prerequisites

Python - We recommend you use the system version where possibly.
- Version 2.7
NumPy - Can be installed through some system package managers or via pip
- Version 1.12.1
pycapnp
- Version 0.5.8 (Linux and OSX only)
CMake

Note: On Windows, Python package dependencies require the following compiler package to be installed: Microsoft Visual C++ Compiler for Python 2.7

The Python dependencies (NumPy and pycapnp) can be installed with pip:

pip install -r bindings/py/requirements.txt

Simple Source Installation (does not support incremental builds)

The easiest way to build from source is as follows. This does not support incremental builds.

python setup.py install

Optionally include --user or other flags to determine where the package is installed.

Testing the Installation

Regardless of how you install nupic.bindings, the nupic-bindings-check command-line script should be installed. Make sure that you include the Python bin installation location in your PATH environment variable and then execute the script:

nupic-bindings-check

Developer Installation

This option is for developers that would like the ability to do incremental builds of the C++ or for those that are using the C++ libraries directly.

Note: The following sub-sections are related to Linux and OSX only. For Windows refer to the external\windows64-gcc\README.md file.

Configure and generate C++ build files:

mkdir -p $NUPIC_CORE/build/scripts
cd $NUPIC_CORE/build/scripts
cmake $NUPIC_CORE -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../release -DPY_EXTENSIONS_DIR=$NUPIC_CORE/bindings/py/src/nupic/bindings

Notes:

This will generate Release build files. For a debug build, change -DCMAKE_BUILD_TYPE to Debug.
To build nupic.core for generating the nupic.bindings python extension, pass -DNUPIC_BUILD_PYEXT_MODULES=ON; it is the default at this time.
To build nupic.core as a standalone static library, pass -DNUPIC_BUILD_PYEXT_MODULES=OFF.
If you have dependencies precompiled but not in standard system locations then you can specify where to find them with -DCMAKE_PREFIX_PATH (for bin/lib) and -DCMAKE_INCLUDE_PATH (for header files).
The -DCMAKE_INSTALL_PREFIX=../release option shown above is optional, and specifies the location where nupic.core should be installed. If omitted, nupic.core will be installed in a system location. Using this option is useful when testing versions of nupic.core language bindings in bindings.
Setting -DPY_EXTENSIONS_DIR copies the Python exension files to the specified directory. If the extensions aren't present when the Python build/installation is invoked then the setup.py file will run the cmake/make process to generate them. Make sure to include this flag if you want to do incremental builds of the Python extensions.
On OSX with multiple Python installs (e.g. via brew) cmake might erroneously pick various pieces from different installs which will likely produce abort trap at runtime. Remove cmake cache and re-run cmake with -DPYTHON_LIBRARY=/path/to/lib/libpython2.7.dylib and -DPYTHON_INCLUDE_DIR=/path/to/include/python2.7 options to override with desired Python install path.
To use Include What You Use during compilation, pass -DNUPIC-IWYU=ON. This requires that IWYU is installed and findable by CMake, with a minimum CMake version of 3.3. IWYU can be installed from https://include-what-you-use.org/ for Windows and Linux, and on OS X using https://github.com/jasonmp85/homebrew-iwyu.
If you would like to install all headers, libraries, and executables to the install location for C++ clients when building the nupic.binding python extensions, pass -NUPIC_TOGGLE_INSTALL=ON.

Build:

# While still in $NUPIC_CORE/build/scripts
make -j3

Note: The -j3 option specifies '3' as the maximum number of parallel jobs/threads that Make will use during the build in order to gain speed. However, you can increase this number depending your CPU.

Install:

# While still in $NUPIC_CORE/build/scripts
make install

Run the tests:

cd $NUPIC_CORE/build/release/bin
./cpp_region_test
./unit_tests
...

Install nupic.bindings Python library:

cd $NUPIC_CORE
python setup.py develop

Note: If the extensions haven't been built already then this will call the cmake/make process to generate them.

If you get a gcc exit code 1, you may consider running this instead:

 python setup.py develop --user

If you are installing on Mac OS X, you must add the instruction ARCHFLAGS="-arch x86_64" before the python call:

ARCHFLAGS="-arch x86_64" python setup.py develop

Alternatively, you can use the install command (as opposed to develop) to copy the installation files rather than link to the source location.

python setup.py install

Note: If you get a "permission denied" error when using the setup commands above, you may add the --user flag to install to a location in your home directory, which should resolve any permissions issues. Doing this, you may need to add this location to your PATH and PYTHONPATH.

Once it is installed, you can import NuPIC bindings library to your python script using:

import nupic.bindings

You can run the nupic.bindings tests via setup.py:

python setup.py test

Using graphical interface

Generate the IDE solution:

Open CMake executable.
Specify the source folder ($NUPIC_CORE/src).
Specify the build system folder ($NUPIC_CORE/build/scripts), i.e. where IDE solution will be created.
Click Generate.
Choose the IDE that interest you (remember that IDE choice is limited to your OS, i.e. Visual Studio is available only on CMake for Windows).

Build:

Open nupic_core.*proj solution file generated on $NUPIC_CORE/build/scripts.
Run ALL_BUILD project from your IDE.

Run the tests:

Run any tests_* project from your IDE (check output panel to see the results).

Build Documentation

Run doxygen, optionally specifying the version as an environment variable:

PROJECT_VERSION=`cat VERSION` doxygen

The results will be written out to the html directory.

Comments

Independent Build Process

This commit includes the compilation of the dynamic/static libraries that compose nupic.core. They are generated by default on nupic.core/build/release folder, however any user could change its destination using cmake -DPROJECT_BUILD_RELEASE_DIR=… or cmake -DPROJECT_BUILD_TEMP_DIR=… command line. Thought this option, Travis at nupic repo will compile the static libraries and put them on /externalfolder.

The output of this library is a static library called nupic.core (I linked with HtmTest, TesteEverything, and all is ok.. :-) ). I'm also trying make CMake generate a dynamic library, but without success (problems with dynamic linking).

Note that neither HtmTest not TestEverything were included, they still are hybrid and Python tests need be removed from them.

Originally reported as https://github.com/numenta/nupic/issues/2570 and https://github.com/numenta/nupic/issues/2543 but now failing with a different error that seems to be internal to nupic.core.

Port Networks tests to Catch and document how to
This PR is to track the work on #10 , using the Catch test framework . Replaces #145 based on merged #147.

Catch stands for C++ Automated Test Cases in Headers, is a modern, C++-native, header-only, framework for unit-tests, TDD and BDD, see https://github.com/philsquared/Catch .

Catch:

is header-only, thus little hassle to add it to nupic.core, unlike gtest

provides all gtest functionalities including JUnit-style xml output as needed by #10

provides BDD-style assertion macros, which is tempting to me who was influenced by ruby's cucumber

This PR intends to complete the following tasks:

[x] make catch generate xUnit style reports as the original #10 requests

[x] porting original tests of class Network in testeverything

[x] generate JUnit-style report for nupic.tools to consume

[x] document how to port the tests based on catch's tutorial about BDD-style assertion macros , so @rhyolight can create a series of newbie tasks as discussed here

remove ASM code with no benefits
During my experiments I figured the hand-tuned ASM code (in ArrayAlgo.hpp, ...) actually has no benefit over pure c++ code, as

compilers progressed over the time

we use compiler optimizations now

NumPy 1.22.0 Release Notes

NumPy 1.22.0 is a big release featuring the work of 153 contributors spread over 609 pull requests. There have been many improvements, highlights are:

Annotations of the main namespace are essentially complete. Upstream is a moving target, so there will likely be further improvements, but the major work is done. This is probably the most user visible enhancement in this release.

A preliminary version of the proposed Array-API is provided. This is a step in creating a standard collection of functions that can be used across application such as CuPy and JAX.

NumPy now has a DLPack backend. DLPack provides a common interchange format for array (tensor) data.

New methods for quantile, percentile, and related functions. The new methods provide a complete set of the methods commonly found in the literature.

A new configurable allocator for use by downstream projects.

These are in addition to the ongoing work to provide SIMD support for commonly used functions, improvements to F2PY, and better documentation.

The Python versions supported in this release are 3.8-3.10, Python 3.7 has been dropped. Note that 32 bit wheels are only provided for Python 3.8 and 3.9 on Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit integer OpenBLAS, which should fix the occasional problems encountered by folks using truly huge arrays.

Expired deprecations

Deprecated numeric style dtype strings have been removed

Using the strings "Bytes0", "Datetime64", "Str0", "Uint32", and "Uint64" as a dtype will now raise a TypeError.

(gh-19539)

Expired deprecations for loads, ndfromtxt, and mafromtxt in npyio

numpy.loads was deprecated in v1.15, with the recommendation that users use pickle.loads instead. ndfromtxt and mafromtxt were both deprecated in v1.17 - users should use numpy.genfromtxt instead with the appropriate value for the usemask parameter.

0.4.5(Aug 17, 2016)
Removed no longer used pre-built Swig executables for various flavors of Linux; nupic.core automatically builds Swig from embedded sources on non-Windows platforms.

DEVOPS-141 Apply an export map to OS X, Linux, and MINGW builds of nupic.bindings shared objects.

Refactor extension build steps into a function shared by algorithms, math, engine_internal, etc. in preparation for adding export maps.

Work around issue in cmake 2.8.7: have external project AprUtil1StaticLib depend directly on external project Apr1StaticLib instead of its library wrapper ${APR1_STATIC_LIB_TARGET}; the latter was incorrectly interperting the dependency as another external project instead of library; but worked correctly on cmake 2.8.12.

Completed wrapping of external static libs in add_library targets

Represent external build of capnproto as single static library with target name ${CAPNP_STATIC_LIB_TARGET} and containing all capnproto library objects.

No need for custom target in CREATE_CAPNPC_COMMAND function, since nupic_core_solo is the only consumer of the custom command's outputs.

Try building nupic_core_solo intermediate static library without specifying system libraries. It's a static library and shouldn't need additional linking information.

Removed nupic_core_solo from installed targets, since it's only an intermediate artifact and not intended to be an output product.

issue-1034 Reorganized build to link nupic_core static library tests against the "combined" nupic_core static library, which is considered an output artifact, instead of nupic_core_solo static lib, which is only an intermediate step.

Use library utils to correctly combine multiple static libraries into a single one.

DEVOPS-135 Implement a hacky work-around by preloading pycapnp's exteions DLL in RTLD_GLOBAL mode, which enables resultion of capnproto references when nupic.bidnings extensions are loaded.

Consider EPSILON while finding minPermanenceSynapse

Refactor to make GCC stop finding false positives

New implementation of GCC_UNINITIALIZED_VAR

DEVOPS-135 Remove capnproto from python extensions shared libs in order to avoid conflict with capnproto methods compiled into pycapnp, possibly compiled with a different compiler/version and with different compiler/linker flags. Instead, we rely on dynamic linking of the necessary symbols from capnproto in pycapnp.

Avoid clang error "unknown warning option '-Wno-maybe-uninitialized'"

Store EPSILON as a static const Permanence

Disable GCC's maybe-uninitialized warnings. Too many false positives.

Fixes nupic.core github issue #1031: rename EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED_STR to EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED and turn it into a list.

fixes floating point comparison bug

Use group_by in TemporalMemory. No more ExcitedColumns.

Untangle the pieces that calculate segment excitation

Get rid of the Cell struct

Initial version of ExtendedTemporalMemory: copy-pasted TM

added blurps for CMAKE_AR and CMAKE_RANLIB

CMakeLists.txt cleaned up, vars renamed, docs updated

Updates pycapnp to 0.5.8.

network-factory adds missing newline to test file

network-factory updates test to ensure created network is unregistered.

deprecate-spec-vars moves documentation from Spec to PyRegion

network-factory adds a test to show that creating a network without any regions or links works

network-factory expose functions to bindings and extend functionality to accept a yaml string

network-factory cleans up includes and makes createNetworkFromYaml public

updated conditional cmake_args, fixes #981

network-factory passes yaml parser instead of path

network-factory ensure Network destructor is called on error

deprecate-spec-vars set defaults for regionLevel and requireSplitterMap and make them optional

Removed the duplicate conditional addition of the NTA_ASM compiler flag from src/CMakeLists.txt. The original remains in CommonCompilerConfig.

Removed check for Wreturn-type compatibility

CMake warning if total memory is less than 1GB

Added back the -O2 flag and the -Wno-return-type flag

GCC Bitness handling

Remove NTA_ASM flag

Removed the inversion of the NTA_ASM logic made by @codedhard

Added CMake flag to make arm specific changes to the build 2. Used new CMake flag to disable inline assembly in build 3. Added NTA_ASM conditional to parts of ArrayAlgo.hpp that didn't use it to enable inline assembly

Add visualization event handlers to Connections class

0.4.3(May 16, 2016)
Adds include-what-you-use option in CMake configuration.

Use the supported mingwpy toolchain from pypi.anaconda.org/carlkl/simple

Define BOOST_MATH_NO_LONG_DOUBLE_MATH_FUNCTIONS for nupic.core source build in attempt to make build work with official mingwpy toolchain

Protect all public member variables (except connections)

Move algorithm details out of the compute method

Split bamboo linux build into debug and release.

Move common environment setup for Bamboo into separate script.

Update SWIG to use local tarfile rather than download from sourceforge.

Store the new lastUsedIteration, don't just increment old one

Unit test: destroyed synapse + segment reuse

Bugfix: Keep the destroyed synapses count in sync.

Walk the columns and segments via ExcitedColumns iterator

Fail loudly when Python regions reassign an output

Disable asserts in release builds

De-duplicate a loop.

Removes 'long double', NTA_QUAD_PRECISION, and Real128 references from our code.

Add Proto for SDR Classifier

TemporalMemory: replace phases with "columnSegmentWalk". Much faster.

MovingAverage.compute() returns updated value

0.4.2(Apr 15, 2016)
Define and use environment variables containing compiler and linker flags specifically for 3rd-party source code.

Revert to installing mingwpy toolchains from https://bitbucket.org/carlkl/mingw-w64-for-python/downloads.

Better rand() approach, won't ever be greater than 1

Stop computing overlaps twice per timestep. 4% faster.

Stop storing segment overlap counts in a map. Now 56% faster.

Enable errors for windows32 build in the matrix.

Use proper float comparisons to avoid issues on 32 vs 64 bit machines.

Perf: When using sets, use std::set::find, not std::find

Swig needs -include cmath when building with mingw toolchain.

Initialize swig_generated_file_compile_flags directly from COMMON_CXX_FLAGS_OPTIMIZED to avoid -Werror.

Comment out header and binary install targets in CapnProto.cmake, since this is a duplicate of the exact same steps in srce/CMakeLists.txt, which installs other externals as well.

Attempt to fix execution of helloregion test from Travis build by modifying .travis.yml to change directory to build/release/bin just as instructed by nupic.core/README.md.

Added a comment about nupic.core's swig wraps relying on the macro CAPNP_LITE to have a value.

Fix windows build of nupic.core's Swig wraps that expects CAPNP_LITE not only to be defined (capnp recommends just defining it), but to actually have a value (non-zero).

Invoke additional nupic.core tests in Travis to make sure that things get tested and tests don't get broken again unnoticed: connections_performance_test helloregion hello_sp_tp prototest

Refactored CommonCompilerConfig.cmake to exposed optimized and unoptimized flag sets. Fixed linux GCC build of CapnProto components by changing its configuration to use unoptimized versions of common flags. Cleaned up use of local variables in src/CMakeFiles.txt. nupic.core/CmakeLists.txt is now the only place that defines REPOSITORY_DIR for use by other modules. Fixed dependency in add_custom_command function inside CREATE_CAPNPC_COMMAND to use passed-in arg SPEC_FILES instead of a property from src/CMakeLists.txt.

Add BITNESS to Swig.cmake

0.4.1(Mar 28, 2016)
Cast arg to UInt32 to avoid call resolution ambiguity on the value.write() method on Win32 platform.

Finish adding support for the Bool type

Expose encoder's 'n' so other regions' inputWidth is calculable from the outside

Remove reference to deleted Linear.cpp.

Run nupic.core encoders via boilerplate Sensor wrapper

Removes Linear.hpp, Linear.cpp, and reference in algorithms.i since it doesn't appear to be used anywhere.
