Hi,

I am trying to train the biomed_roberta_base model on the chemprot dataset using the provided scripts.train python command and encounter the below issues.

The above dataset and models have been downloaded as stated in the README of the master branch. Also since the mentioned environment wasn't working for me I am using the below conda environment

Please let me know how to solve the above issue. It seems like the tokenizer asks for a vocab file but I am not sure how to provide one.

您解决了此类问题了么？现在我遇到这个问题了。不知怎么处理了？

Solution is to upgrade to pytorch-transformers==1.2.0
