Not getting accuracy on MMRecognition SAR Model Training

HI @gaotongxiao

I am training Custom dataset for Text recognition using SAR Model. I have total 7K plus images for training. Can you please help me how long should I have to wait for trained model. As of now it completed 65th epoch and the Accuracy matric at 65th epoch is as below:

2022-03-21 08:06:45,433 - mmocr - INFO - Epoch(val) [65][100] 0_word_acc: 0.0000, 0_word_acc_ignore_case: 0.0000, 0_word_acc_ignore_case_symbol: 0.0000, 0_char_recall: 0.1346, 0_char_precision: 0.1089, 0_1-N.E.D: 0.0776

As you can see precision and recall are very less.

Also can you please suggest any preprocessing technique which you are aware to achieve good accuracy with respect to text recognition task?

Here is the attached SS of training continuation:

TypeError: 'DataContainer' object is not subscriptable/TypeError: SDMGR: __init__() got an unexpected keyword argument 'pretrained'
Checklist

I have searched related issues but cannot get the expected help.

Describe the bug I have trained the SDMGR model for 10 images and now Testing the SDMGR model to Visualize the Predictions.But iam getting Type error ypeError: 'DataContainer' object is not subscriptable .Please help me to resolve.

Reproduction

What command or script did you run?

I ran the following command :

python /disk2/mmocr/tools/test.py /disk2/mmocr/configs/kie/sdmgr/sdmgr_unet16_60e_wildreceipt_min_DS.py /disk2/mmocr/sdmgr/latest.pth --show-dir /disk2/mmocr/mmocr_kie_output Use load_from_local loader [ ] 0/1, elapsed: 0s, ETA:Traceback (most recent call last): File "/disk2/mmocr/tools/test.py", line 243, in main() File "/disk2/mmocr/tools/test.py", line 213, in main args.show_score_thr) File "/disk2/anaconda3/envs/open-mmlab/lib/python3.7/site-packages/mmdet/apis/test.py", line 31, in single_gpu_test if batch_size == 1 and isinstance(data['img'][0], torch.Tensor): TypeError: 'DataContainer' object is not subscriptable

Also iam using script as below if i run the script i get the error TypeError: SDMGR: init() got an unexpected keyword argument 'pretrained'

During handling of the above exception, another exception occurred:

Did you make any modifications on the code or config? Did you understand what you have modified? I have changed few parameters of config file sdmgr_unet16_60e_wildreceipt.py

What dataset did you use? Wildreceipt dataset

Training data and code for key-information-extraction

Hi. Amazing work at https://mmocr.readthedocs.io/en/latest/demo.html#example-4-text-detection-recognition-key-information-extraction. Where can I code code for training the model for key-information extraction?

P.S If it is not available in docs, I can send a PR.

I think, the type (e.g., AnnFileLoader and OCRDataset )has been assigned properly.

May I know what is the issue.

The full code and issue can be reproduced via this Notebook.

KIE annotation tool

Hey! I really appreciate your excellent work! I want to add some of my own examples of annotated receipts to the wildreceipt dataset to train the model with my dataset. Is there any annotation tool available? Or is there a converter from other formats?

Reproduce total-text emperiment by FCENet

Abstract： I followed MMOCR Documentation reproduce the CTW1500 and Icdar 2015 emperiments, and followed the ctw1500 config create Total-text. Download Total-text imgs and annotations(.txt) from https://github.com/cs-chan/Total-Text-Dataset/tree/master/Dataset, and used tools/totaltext_convert.py convert totaltxt to icdardataset. About Fcenet_targets and textsnake_targets, i am not alter anywhere.But i found something wrong when i run train.py, whatever used or not convert annotations.

Releases(v1.0.0rc4)

v1.0.0rc4(Dec 6, 2022)
Highlights

Dataset Preparer can automatically generate base dataset configs at the end of the preparation process, and supports 6 more datasets: IIIT5k, CUTE80, ICDAR2013, ICDAR2015, SVT, SVTP.

Introducing our projects/ folder - implementing new models and features into OpenMMLab's algorithm libraries has long been complained to be troublesome due to the rigorous requirements on code quality, which could hinder the fast iteration of SOTA models and might discourage community members from sharing their latest outcome here. We now introduce projects/ folder, where some experimental features, frameworks and models can be placed, only needed to satisfy the minimum requirement on the code quality. Everyone is welcome to post their implementation of any great ideas in this folder! We also add the first example project to illustrate what we expect a good project to have (check out the raw content of README.md for more info!).

Inside the projects/ folder, we are releasing the preview version of ABCNet, which is the first implementation of text spotting models in MMOCR. It's inference-only now, but the full implementation will be available very soon.

v1.0.0rc3(Nov 3, 2022)
Highlights

We release several pretrained models using oCLIP-ResNet as the backbone, which is a ResNet variant trained with oCLIP and can significantly boost the performance of text detection models.

Preparing datasets is troublesome and tedious, especially in OCR domain where multiple datasets are usually required. In order to free our users from laborious work, we designed a Dataset Preparer to help you get a bunch of datasets ready for use, with only one line of command! Dataset Preparer is also crafted to consist of a series of reusable modules, each responsible for handling one of the standardized phases throughout the preparation process, shortening the development cycle on supporting new datasets.

It's now possible to train/test models through Python Interface. For example, you can train a model under mmocr/ directory in this way:

# an example of how to use such modifications is shown as the following: from mmocr.tools.train import TrainArg, parse_args, run_train_cmd args = TrainArg(config='/path/to/config.py') args.add_arg('--work-dir', '/path/to/dir') args = parse_args(args.arg_list) run_train_cmd(args)

See PR #1138 for more details.

Besides, release candidates for MMOCR 1.0 with tons of new features are available at 1.x branch now! Check out the changelog for more information about the features, and maintenance plan for how we will maintain MMOCR in the future.

v1.0.0rc0(Sep 1, 2022)
We are excited to announce the release of MMOCR 1.0.0rc0! MMOCR 1.0.0rc0 is the first version of MMOCR 1.x, a part of the OpenMMLab 2.0 projects. Built upon the new training engine, MMOCR 1.x unifies the interfaces of dataset, models, evaluation, and visualization with faster training and testing speed.

Highlights

New engines. MMOCR 1.x is based on MMEngine, which provides a general and powerful runner that allows more flexible customizations and significantly simplifies the entrypoints of high-level interfaces.

Unified interfaces. As a part of the OpenMMLab 2.0 projects, MMOCR 1.x unifies and refactors the interfaces and internal logics of train, testing, datasets, models, evaluation, and visualization. All the OpenMMLab 2.0 projects share the same design in those interfaces and logics to allow the emergence of multi-task/modality algorithms.

Cross project calling. Benefiting from the unified design, you can use the models implemented in other OpenMMLab projects, such as MMDet. We provide an example of how to use MMDetection's Mask R-CNN through MMDetWrapper. Check our documents for more details. More wrappers will be released in the future.

Stronger visualization. We provide a series of useful tools which are mostly based on brand-new visualizers. As a result, it is more convenient for the users to explore the models and datasets now.

More documentation and tutorials. We add a bunch of documentation and tutorials to help users get started more smoothly. Read it here.

Breaking Changes

We briefly list the major breaking changes here. We also have the migration guide that provides complete details and migration instructions.

Dependencies

MMOCR 1.x relies on MMEngine to run. MMEngine is a new foundational library for training deep learning models in OpenMMLab 2.0 models. The dependencies of file IO and training are migrated from MMCV 1.x to MMEngine.

MMOCR 1.x relies on MMCV>=2.0.0rc0. Although MMCV no longer maintains the training functionalities since 2.0.0rc0, MMOCR 1.x relies on the data transforms, CUDA operators, and image processing interfaces in MMCV. Note that the package mmcv is the version that provide pre-built CUDA operators and mmcv-lite does not since MMCV 2.0.0rc0, while mmcv-full has been deprecated.

Training and testing

MMOCR 1.x uses Runner in MMEngine rather than that in MMCV. The new Runner implements and unifies the building logic of dataset, model, evaluation, and visualizer. Therefore, MMOCR 1.x no longer maintains the building logics of those modules in mmocr.train.apis and tools/train.py. Those code have been migrated into MMEngine. Please refer to the migration guide of Runner in MMEngine for more details.

The Runner in MMEngine also supports testing and validation. The testing scripts are also simplified, which has similar logic as that in training scripts to build the runner.

The execution points of hooks in the new Runner have been enriched to allow more flexible customization. Please refer to the migration guide of Hook in MMEngine for more details.

Learning rate and momentum schedules has been migrated from Hook to Parameter Scheduler in MMEngine. Please refer to the migration guide of Parameter Scheduler in MMEngine for more details.

Configs

The Runner in MMEngine uses a different config structures to ease the understanding of the components in runner. Users can read the config example of MMOCR or refer to the migration guide in MMEngine for migration details.

The file names of configs and models are also refactored to follow the new rules unified across OpenMMLab 2.0 projects. Please refer to the user guides of config for more details.

Dataset

The Dataset classes implemented in MMOCR 1.x all inherits from the BaseDetDataset, which inherits from the BaseDataset in MMEngine. There are several changes of Dataset in MMOCR 1.x.

All the datasets support serializing the data list to reduce the memory when multiple workers are built to accelerate data loading.

The interfaces are changed accordingly.

Data Transforms

Data transforms in MMOCR 1.x all inherits from those in MMCV>=2.0.0rc0, which follows a new convention in OpenMMLab 2.0 projects. The changes are listed below:

The interfaces are also changed. Please refer to the API Reference

The functionalities of some data transforms (e.g., Resize) are decomposed into several transforms.

The same data transforms in different OpenMMLab 2.0 libraries have the same augmentation implementation and the logic of the same arguments, i.e., Resize in MMDet 3.x and MMOCR 1.x will resize the image in the exact same manner given the same arguments.

Model

The models in MMOCR 1.x all inherit from BaseModel in MMEngine, which defines a new convention of models in OpenMMLab 2.0 projects. Users can refer to the tutorial of model in MMEngine for more details. Accordingly, there are several changes as the following:

The model interfaces, including the input and output formats, are significantly simplified and unified following the new convention in MMOCR 1.x. Specifically, all the input data in training and testing are packed into inputs and data_samples, where inputs contains model inputs like a list of image tensors, and data_samples contains other information of the current data sample such as ground truths and model predictions. In this way, different tasks in MMOCR 1.x can share the same input arguments, which makes the models more general and suitable for multi-task learning.

The model has a data preprocessor module, which is used to pre-process the input data of model. In MMOCR 1.x, the data preprocessor usually does the necessary steps to form the input images into a batch, such as padding. It can also serve as a place for some special data augmentations or more efficient data transformations like normalization.

The internal logic of model has been changed. In MMOCR 0.x, model used forward_train and simple_test to deal with different model forward logics. In MMOCR 1.x and OpenMMLab 2.0, the forward function has three modes: loss, predict, and tensor for training, inference, and tracing or other purposes, respectively. The forward function calls self.loss(), self.predict(), and self._forward() given the modes loss, predict, and tensor, respectively.

Evaluation

MMOCR 1.x mainly implements corresponding metrics for each task, which are manipulated by Evaluator to complete the evaluation. In addition, users can build an evaluator in MMOCR 1.x to conduct offline evaluation, i.e., evaluate predictions that may not be produced by MMOCR, prediction follows our dataset conventions. More details can be find in the Evaluation Tutorial in MMEngine.

Visualization

The functions of visualization in MMOCR 1.x are removed. Instead, in OpenMMLab 2.0 projects, we use Visualizer to visualize data. MMOCR 1.x implements TextDetLocalVisualizer, TextRecogLocalVisualizer, and KIELocalVisualizer to allow visualization of ground truths, model predictions, and feature maps, etc., at any place, for the three tasks supported in MMOCR. It also supports dumping the visualization data to any external visualization backends such as Tensorboard and Wandb. Check our Visualization Document for more details.

Improvements

Most models enjoy a performance improvement from the new framework and refactor of data transforms. For example, in MMOCR 1.x, DBNet-R50 achieves 0.854 hmean score on ICDAR 2015, while the counterpart can only get 0.840 hmean score in MMOCR 0.x.

Support mixed precision training of most of the models. However, the rest models are not supported yet because the operators they used might not be representable in fp16. We will update the documentation and list the results of mixed precision training.

Ongoing changes

Test-time augmentation: which was supported in MMOCR 0.x, is not implemented yet in this version due to limited time slot. We will support it in the following releases with a new and simplified design.

Inference interfaces: unified inference interfaces will be supported in the future to ease the use of released models.

Interfaces of useful tools that can be used in notebook: more useful tools that are implemented in the tools/ directory will have their python interfaces so that they can be used through notebook and in downstream libraries.

Documentation: we will add more design docs, tutorials, and migration guidance so that the community can deep dive into our new design, participate the future development, and smoothly migrate downstream libraries to MMOCR 1.x.

v0.6.0(May 5, 2022)
Highlights

A new recognition algorithm MASTER has been added into MMOCR, which was the championship solution for the "ICDAR 2021 Competition on Scientific Table Image Recognition to Latex"! The model pre-trained on SynthText and MJSynth is available for testing! Credit to @JiaquanYe

DBNet++ has been released now! A new Adaptive Scale Fusion module has been equipped for feature enhancement. Benefiting from this, the new model achieved 2% better h-mean score than its predecessor on the ICDAR2015 dataset.

Three more dataset converters are added: LSVT, RCTW and HierText. Check the dataset zoo (Det & Recog) to explore further information.

To enhance the data storage efficiency, MMOCR now supports loading both images and labels from .lmdb format annotations for the text recognition task. To enable such a feature, the new lmdb_converter.py is ready for use to pack your cropped images and labels into an lmdb file. For a detailed tutorial, please refer to the following sections and the doc.

Testing models on multiple datasets is a widely used evaluation strategy. MMOCR now supports automatically reporting mean scores when there is more than one dataset to evaluate, which enables a more convenient comparison between checkpoints. Doc

Evaluation is more flexible and customizable now. For text detection tasks, you can set the score threshold range where the best results might come out. (Doc) If too many results are flooding your text recognition train log, you can trim it by specifying a subset of metrics in evaluation config. Check out the Evaluation section for details.

MMOCR provides a script to convert the .json labels obtained by the popular annotation toolkit Labelme to MMOCR-supported data format. @Y-M-Y contributed a log analysis tool that helps users gain a better understanding of the entire training process. Read tutorial docs to get started.

Lmdb Dataset

Reading images or labels from files can be slow when data are excessive, e.g. on a scale of millions. Besides, in academia, most of the scene text recognition datasets are stored in lmdb format, including images and labels. To get closer to the mainstream practice and enhance the data storage efficiency, MMOCR now officially supports loading images and labels from lmdb datasets via a new pipeline LoadImageFromLMDB. This section is intended to serve as a quick walkthrough for you to master this update and apply it to facilitate your research.

Specifications

To better align with the academic community, MMOCR now requires the following specifications for lmdb datasets:

The parameter describing the data volume of the dataset is num-samples instead of total_number (deprecated).

Images and labels are stored with keys in the form of image-000000001 and label-000000001, respectively.

Usage

Use existing academic lmdb datasets if they meet the specifications; or the tool provided by MMOCR to pack images & annotations into a lmdb dataset.

Previously, MMOCR had a function txt2lmdb (deprecated) that only supported converting labels to lmdb format. However, it is quite different from academic lmdb datasets, which usually contain both images and labels. Now MMOCR provides a new utility lmdb_converter to convert recognition datasets with both images and labels to lmdb format.

Say that your recognition data in MMOCR's format are organized as follows. (See an example in ocr_toy_dataset).

# Directory structure ├──img_path | |—— img1.jpg | |—— img2.jpg | |—— ... |——label.txt (or label.jsonl) # Annotation format label.txt: img1.jpg HELLO img2.jpg WORLD ... label.jsonl: {'filename':'img1.jpg', 'text':'HELLO'} {'filename':'img2.jpg', 'text':'WORLD'} ...

Then pack these files up:

python tools/data/utils/lmdb_converter.py {PATH_TO_LABEL} {OUTPUT_PATH} --i {PATH_TO_IMAGES}

Check out tools.md for more details.

The second step is to modify the configuration files. For example, to train CRNN on MJ and ST datasets:

Set parser as LineJsonParser and file_format as 'lmdb' in dataset config

# configs/_base_/recog_datasets/ST_MJ_train.py train1 = dict( type='OCRDataset', img_prefix=train_img_prefix1, ann_file=train_ann_file1, loader=dict( type='AnnFileLoader', repeat=1, file_format='lmdb', parser=dict( type='LineJsonParser', keys=['filename', 'text'], )), pipeline=None, test_mode=False)

Use LoadImageFromLMDB in pipeline:

# configs/_base_/recog_pipelines/crnn_pipeline.py train_pipeline = [ dict(type='LoadImageFromLMDB', color_type='grayscale'), ...

You are good to go! Start training and MMOCR will load data from your lmdb dataset.

Highlights

MMOCR now supports SPACE recognition! (What a prominent feature!) Users only need to convert the recognition annotations that contain spaces from a plain .txt file to JSON line format .jsonl, and then revise a few configurations to enable the LineJsonParser. For more information, please read our step-by-step tutorial.

Tesseract is now available in MMOCR! While MMOCR is more flexible to support various downstream tasks, users might sometimes not be satisfied with DL models and would like to turn to effective legacy solutions. Therefore, we offer this option in mmocr.utils.ocr by wrapping Tesseract as a detector and/or recognizer. Users can easily create an MMOCR object by MMOCR(det=’Tesseract’, recog=’Tesseract’).

We release data converters for 16 widely used OCR datasets, including multiple scenarios such as document, handwritten, and scene text. Now it is more convenient to generate annotation files for these datasets. Check the dataset zoo ( Det & Recog ) to explore further information.

Migration Guide - ResNet

Some refactoring processes are still going on. For text recognition models, we unified the ResNet-like architectures which are used as backbones. By introducing stage-wise and block-wise plugins, the refactored ResNet is highly flexible to support existing models, like ResNet31 and ResNet45, and other future designs of ResNet variants.

Plugin

Plugin is a module category inherited from MMCV's implementation of PLUGIN_LAYERS, which can be inserted between each stage of ResNet or into a basicblock. You can find a simple implementation of plugin at mmocr/models/textrecog/plugins/common.py, or click the button below.

Plugin Example

@PLUGIN_LAYERS.register_module() class Maxpool2d(nn.Module): """A wrapper around nn.Maxpool2d(). Args: kernel_size (int or tuple(int)): Kernel size for max pooling layer stride (int or tuple(int)): Stride for max pooling layer padding (int or tuple(int)): Padding for pooling layer """ def __init__(self, kernel_size, stride, padding=0, **kwargs): super(Maxpool2d, self).__init__() self.model = nn.MaxPool2d(kernel_size, stride, padding) def forward(self, x): """ Args: x (Tensor): Input feature map Returns: Tensor: The tensor after Maxpooling layer. """ return self.model(x)

Stage-wise Plugins

ResNet is composed of stages, and each stage is composed of blocks. E.g., ResNet18 is composed of 4 stages, and each stage is composed of basicblocks. For each stage, we provide two ports to insert stage-wise plugins by giving plugins parameters in ResNet.

[port1: before stage] ---> [stage] ---> [port2: after stage]

E.g. Using a ResNet with four stages as example. Suppose we want to insert an additional convolution layer before each stage, and an additional convolution layer at stage 1, 2, 4. Then you can define the special ResNet18 like this

resnet18_speical = ResNet( # for simplicity, some required # parameters are omitted plugins=[ dict( cfg=dict( type='ConvModule', kernel_size=3, stride=1, padding=1, norm_cfg=dict(type='BN'), act_cfg=dict(type='ReLU')), stages=(True, True, True, True), position='before_stage') dict( cfg=dict( type='ConvModule', kernel_size=3, stride=1, padding=1, norm_cfg=dict(type='BN'), act_cfg=dict(type='ReLU')), stages=(True, True, False, True), position='after_stage') ])

You can also insert more than one plugin in each port and those plugins will be executed in order. Let's take ResNet in MASTER as an example:

Multiple Plugins Example

ResNet in Master is based on ResNet31. And after each stage, a module named GCAModule will be used. The GCAModule is inserted before the stage-wise convolution layer in ResNet31. In conlusion, there will be two plugins at after_stage port in the same time.

resnet_master = ResNet( # for simplicity, some required # parameters are omitted plugins=[ dict( cfg=dict(type='Maxpool2d', kernel_size=2, stride=(2, 2)), stages=(True, True, False, False), position='before_stage'), dict( cfg=dict(type='Maxpool2d', kernel_size=(2, 1), stride=(2, 1)), stages=(False, False, True, False), position='before_stage'), dict( cfg=dict(type='GCAModule', kernel_size=3, stride=1, padding=1), stages=[True, True, True, True], position='after_stage'), dict( cfg=dict( type='ConvModule', kernel_size=3, stride=1, padding=1, norm_cfg=dict(type='BN'), act_cfg=dict(type='ReLU')), stages=(True, True, True, True), position='after_stage') ])

In each plugin, we will pass two parameters (in_channels, out_channels) to support operations that need the information of current channels.

Block-wise Plugin (Experimental)

We also refactored the BasicBlock used in ResNet. Now it can be customized with block-wise plugins. Check here for more details.

BasicBlock is composed of two convolution layer in the main branch and a shortcut branch. We provide four ports to insert plugins.

    [port1: before_conv1] ---> [conv1] --->
    [port2: after_conv1] ---> [conv2] --->
    [port3: after_conv2] ---> +(shortcut) ---> [port4: after_shortcut]

In each plugin, we will pass a parameter in_channels to support operations that need the information of current channels.

E.g. Build a ResNet with customized BasicBlock with an additional convolution layer before conv1:

Block-wise Plugin Example

resnet_31 = ResNet(
        in_channels=3,
        stem_channels=[64, 128],
        block_cfgs=dict(type='BasicBlock'),
        arch_layers=[1, 2, 5, 3],
        arch_channels=[256, 256, 512, 512],
        strides=[1, 1, 1, 1],
        plugins=[
            dict(
                cfg=dict(type='Maxpool2d',
                kernel_size=2,
                stride=(2, 2)),
                stages=(True, True, False, False),
                position='before_stage'),
            dict(
                cfg=dict(type='Maxpool2d',
                kernel_size=(2, 1),
                stride=(2, 1)),
                stages=(False, False, True, False),
                position='before_stage'),
            dict(
                cfg=dict(
                type='ConvModule',
                kernel_size=3,
                stride=1,
                padding=1,
                norm_cfg=dict(type='BN'),
                act_cfg=dict(type='ReLU')),
                stages=(True, True, True, True),
                position='after_stage')
        ])

Full Examples

ResNet without plugins

ResNet45 is used in ASTER and ABINet without any plugins.

resnet45_aster = ResNet(
    in_channels=3,
    stem_channels=[64, 128],
    block_cfgs=dict(type='BasicBlock', use_conv1x1='True'),
    arch_layers=[3, 4, 6, 6, 3],
    arch_channels=[32, 64, 128, 256, 512],
    strides=[(2, 2), (2, 2), (2, 1), (2, 1), (2, 1)])

resnet45_abi = ResNet(
    in_channels=3,
    stem_channels=32,
    block_cfgs=dict(type='BasicBlock', use_conv1x1='True'),
    arch_layers=[3, 4, 6, 6, 3],
    arch_channels=[32, 64, 128, 256, 512],
    strides=[2, 1, 2, 1, 1])

ResNet with plugins

ResNet31 is a typical architecture to use stage-wise plugins. Before the first three stages, Maxpooling layer is used. After each stage, a convolution layer with BN and ReLU is used.

resnet_31 = ResNet(
    in_channels=3,
    stem_channels=[64, 128],
    block_cfgs=dict(type='BasicBlock'),
    arch_layers=[1, 2, 5, 3],
    arch_channels=[256, 256, 512, 512],
    strides=[1, 1, 1, 1],
    plugins=[
        dict(
            cfg=dict(type='Maxpool2d',
            kernel_size=2,
            stride=(2, 2)),
            stages=(True, True, False, False),
            position='before_stage'),
        dict(
            cfg=dict(type='Maxpool2d',
            kernel_size=(2, 1),
            stride=(2, 1)),
            stages=(False, False, True, False),
            position='before_stage'),
        dict(
            cfg=dict(
            type='ConvModule',
            kernel_size=3,
            stride=1,
            padding=1,
            norm_cfg=dict(type='BN'),
            act_cfg=dict(type='ReLU')),
            stages=(True, True, True, True),
            position='after_stage')
    ])

Migration Guide - Dataset Annotation Loader

The annotation loaders, LmdbLoader and HardDiskLoader, are unified into AnnFileLoader for a more consistent design and wider support on different file formats and storage backends. AnnFileLoader can load the annotations from disk(default), http and petrel backend, and parse the annotation in txt or lmdb format. LmdbLoader and HardDiskLoader are deprecated, and users are recommended to modify their configs to use the new AnnFileLoader. Users can migrate their legacy loader HardDiskLoader referring to the following example:

# Legacy config
train = dict(
    type='OCRDataset',
    ...
    loader=dict(
        type='HardDiskLoader',
        ...))

# Suggested config
train = dict(
    type='OCRDataset',
    ...
    loader=dict(
        type='AnnFileLoader',
        file_storage_backend='disk',
        file_format='txt',
        ...))

Similarly, using AnnFileLoader with file_format='lmdb' instead of LmdbLoader is strongly recommended.

v0.4.0(Dec 15, 2021)

Highlights

We release a new text recognition model - ABINet (CVPR 2021, Oral). With dedicated model design and useful data augmentation transforms, ABINet achieves the best performance on irregular text recognition tasks. Check it out!
We are also working hard to fulfill the requests from our community. OpenSet KIE is one of the achievements, which extends the application of SDMGR from text node classification to node-pair relation extraction. We also provide a demo script to convert WildReceipt to open set domain, though it may not take full advantage of the OpenSet format. For more information, read our tutorial.
APIs of models can be exposed through TorchServe. Docs

Breaking Changes & Migration Guide

Postprocessor

Some refactoring processes are still going on. For all text detection models, we unified their decode implementations into a new module category, POSTPROCESSOR, which is responsible for decoding different raw outputs into boundary instances. In all text detection configs, the text_repr_type argument in bbox_head is deprecated and will be removed in the future release.

Migration Guide: Find a similar line from detection model's config:

text_repr_type=xxx,

And replace it with

postprocessor=dict(type='{MODEL_NAME}Postprocessor', text_repr_type=xxx)),

Take a snippet of PANet's config as an example. Before the change, its config for bbox_head looks like:

    bbox_head=dict(
        type='PANHead',
        text_repr_type='poly',
        in_channels=[128, 128, 128, 128],
        out_channels=6,
        loss=dict(type='PANLoss')),

Afterwards:

    bbox_head=dict(
    type='PANHead',
    in_channels=[128, 128, 128, 128],
    out_channels=6,
    loss=dict(type='PANLoss'),
    postprocessor=dict(type='PANPostprocessor', text_repr_type='poly')),

There are other postprocessors and each takes different arguments. Interested users can find their interfaces or implementations in mmocr/models/textdet/postprocess or through our api docs.

New Config Structure

We reorganized the configs/ directory by extracting reusable sections into configs/_base_. Now the directory tree of configs/_base_ is organized as follows:

_base_
├── det_datasets
├── det_models
├── det_pipelines
├── recog_datasets
├── recog_models
├── recog_pipelines
└── schedules

Most of model configs are making full use of base configs now, which makes the overall structural clearer and facilitates fair comparison across models. Despite the seemingly significant hierarchical difference, these changes would not break the backward compatibility as the names of model configs remain the same.

v0.3.0(Aug 25, 2021)

Highlights

We add a new text recognition model -- SATRN! Its pretrained checkpoint achieves the best performance over other provided text recognition models. A lighter version of SATRN is also released which can obtain ~98% of the performance of the original model with only 45 MB in size. (@2793145003) #405
Improve the demo script, ocr.py, which supports applying end-to-end text detection, text recognition and key information extraction models on images with easy-to-use commands. Users can find its full documentation in the demo section. (@samayala22, @manjrekarom) #371, #386, #400, #374, #428
Our documentation is reorganized into a clearer structure. More useful contents are on the way! #409, #454
The requirement of Polygon3 is removed since this project is no longer maintained or distributed. We unified all its references to equivalent substitutions in shapely instead. #448

Breaking Changes & Migration Guide

Upgrade version requirement of MMDetection to 2.14.0 to avoid bugs #382
MMOCR now has its own model and layer registries inherited from MMDetection's or MMCV's counterparts. (#436) The modified hierarchical structure of the model registries are now organized as follows.

mmcv.MODELS -> mmdet.BACKBONES -> BACKBONES
mmcv.MODELS -> mmdet.NECKS -> NECKS
mmcv.MODELS -> mmdet.ROI_EXTRACTORS -> ROI_EXTRACTORS
mmcv.MODELS -> mmdet.HEADS -> HEADS
mmcv.MODELS -> mmdet.LOSSES -> LOSSES
mmcv.MODELS -> mmdet.DETECTORS -> DETECTORS
mmcv.ACTIVATION_LAYERS -> ACTIVATION_LAYERS
mmcv.UPSAMPLE_LAYERS -> UPSAMPLE_LAYERS

To migrate your old implementation to our new backend, you need to change the import path of any registries and their corresponding builder functions (including build_detectors) from mmdet.models.builder to mmocr.models.builder. If you have referred to any model or layer of MMDetection or MMCV in your model config, you need to add mmdet. or mmcv. prefix to its name to inform the model builder of the right namespace to work on.

Interested users may check out MMCV's tutorial on Registry for in-depth explanations on its mechanism.
