## Latest Updates

**The default branch is now `main` and the code on the branch has been upgraded to v1.0.0. The old `main` branch (v0.6.3) code now exists on the `0.x` branch.** If you have been using the `main` branch and encounter upgrade issues, please read the [Migration Guide](https://mmocr.readthedocs.io/en/dev-1.x/migration/overview.html) and notes on [Branches](https://mmocr.readthedocs.io/en/dev-1.x/migration/branches.html) .

v1.0.0 was released in 2023-04-06. Major updates from 1.0.0rc6 include:

1. Support for SCUT-CTW1500, SynthText, and MJSynth datasets in Dataset Preparer

2. Updated FAQ and documentation

3. Deprecation of file_client_args in favor of backend_args

4. Added a new MMOCR tutorial notebook

To know more about the updates in MMOCR 1.0, please refer to [What's New in MMOCR 1.x](https://mmocr.readthedocs.io/en/dev-1.x/migration/news.html), or

Read [Changelog](https://mmocr.readthedocs.io/en/dev-1.x/notes/changelog.html) for more details!

## Introduction

MMOCR is an open-source toolbox based on PyTorch and mmdetection for text detection, text recognition, and the corresponding downstream tasks including key information extraction. It is part of the [OpenMMLab](https://openmmlab.com/) project.

The main branch works with **PyTorch 1.6+**.



  



### Major Features

- **Comprehensive Pipeline**

  The toolbox supports not only text detection and text recognition, but also their downstream tasks such as key information extraction.

- **Multiple Models**

  The toolbox supports a wide variety of state-of-the-art models for text detection, text recognition and key information extraction.

- **Modular Design**

  The modular design of MMOCR enables users to define their own optimizers, data preprocessors, and model components such as backbones, necks and heads as well as losses. Please refer to [Overview](https://mmocr.readthedocs.io/en/dev-1.x/get_started/overview.html) for how to construct a customized model.

- **Numerous Utilities**

  The toolbox provides a comprehensive set of utilities which can help users assess the performance of models. It includes visualizers which allow visualization of images, ground truths as well as predicted bounding boxes, and a validation tool for evaluating checkpoints during training.  It also includes data converters to demonstrate how to convert your own data to the annotation files which the toolbox supports.

## Installation

MMOCR depends on [PyTorch](https://pytorch.org/), [MMEngine](https://github.com/open-mmlab/mmengine), [MMCV](https://github.com/open-mmlab/mmcv) and [MMDetection](https://github.com/open-mmlab/mmdetection).

Below are quick steps for installation.

Please refer to [Install Guide](https://mmocr.readthedocs.io/en/dev-1.x/get_started/install.html) for more detailed instruction.

```shell

conda create -n open-mmlab python=3.8 pytorch=1.10 cudatoolkit=11.3 torchvision -c pytorch -y

conda activate open-mmlab

pip3 install openmim

git clone https://github.com/open-mmlab/mmocr.git

cd mmocr

mim install -e .

```
