Server got error after open on browser

Hi, I run 'python server/main.py' and I got this error after open the server address:

OSError: Unable to load vocabulary from file. Please check that the provided vocabulary is accessible and not corrupted.

How could I fix this?

Weird, I haven't seen this one before. It seems like the Transformers library is having trouble loading the vocabulary for the tokenizer corresponding to the default "bert-base-cased" model.

1. What version of Transformers are you using?
2. Since developing this package, the default cache Huggingface directory has changed. Can you check what contents are in your ~/.cache/huggingface? Perhaps deleting some parts of that folder that are corrupted could help
