## MMOCR Support

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 a part of the [OpenMMLab](https://openmmlab.com/) project.

### MMOCR installation tutorial

Please refer to [install.md](https://github.com/open-mmlab/mmocr/blob/main/docs/install.md) for installation.
