Deepke

1. Add data [annotation instructions](https://github.com/zjunlp/DeepKE/blob/main/README_TAG.md) for entity recognition and relation extraction.
2. Add automatic labelling of weakly supervised data ([entity recognition](https://github.com/zjunlp/DeepKE/tree/main/example/ner/prepare-data) and [relation extraction](https://github.com/zjunlp/DeepKE/tree/main/example/re/prepare-data)).
3. Optimize [multi-GPU training](https://github.com/zjunlp/DeepKE/tree/main/example/re/standard).
4. Fix some bugs.

We have added the following functions in this version:
1、Add multi modal entity extraction and multi modal relation extraction.
2、Add off-the-shelf models based on cnSchema
3、Add lstm-crf model for entity extraction
4、Add data augmentation for low resource relation extraction
5、Fix some bugs
