Hi, thanks for sharing your work!
I have the following error when trying to run the bert_cnn experiment:

Can you take a look at this issue?

Sure will take a look. I think its related to allenai/allennlp#3103

@tingkai-zhang Were you able to get it working?

Really sorry for the late reply. I have time to look into this now.
