Highlights

1. Visualizing edge weights in OpenSet KIE is now supported! https://github.com/open-mmlab/mmocr/pull/677
2. Some configurations have been optimized to significantly speed up the training and testing processes! Don't worry - you can still tune these parameters in case these modifications do not work. https://github.com/open-mmlab/mmocr/pull/757
3. Now you can use CPU to train/debug your model! https://github.com/open-mmlab/mmocr/pull/752
4. We have fixed a severe bug that causes users unable to call mmocr.apis.test with our pre-built wheels. https://github.com/open-mmlab/mmocr/pull/667
