Performance Issue about pretrained bert migration from tensorflow to pytorch
# ❓ Questions & Help

Hi, 
I have a question about migration from tensorflow to pytorch.
if I change pretrained BERT with google tensorflow 1.x version to pytorch transformers BERT through transformers-cli, performance drops a lot. I wonder why.

Is there any similar case?
Are you using the latest version? `transformers` and not `pytorch-transformers`. It works with both TF2 and PT. You can test both and compare.<|||||>This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
