引入BertTokenizer出现OSError: Can‘t load tokenizer for ‘bert-base-uncased‘.

今天在跑一个模型的时候出现该报错，完整报错为：

OSError: Can't load tokenizer for 'bert-base-uncased'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name. Otherwise, make sure 'bert-base-uncased' is the correct path to a directory containing all relevant files for a BertTokenizer tokenizer.

找了半天一直没找到解决方案，最后发现是transformers库的版本问题，要么在终端运行：

conda install transformers
要么就是更新该库transformers

就能解决了。
