-```bash
-pip install git+https://github.com/JunnYu/WoBERT_pytorch.git
-```
+注意：transformers版本需要>=4.7.0
+WoBertTokenizer的实现与RoFormerTokenizer是一样的，因此使用RoFormerTokenizer就可以了
 
 ## 使用
 ```python
 import torch
 from transformers import BertForMaskedLM as WoBertForMaskedLM
-from wobert import WoBertTokenizer
+from transformers import RoFormerTokenizer as WoBertTokenizer
