Hi there,

error on line:

Resulting in the following errror:

The above exception was the direct cause of the following exception:

Unsure as to how to proceed.
PyTorch = 1.0.1
Unsure of the version of transformers as it's not appearing in my anaconda packages. But the rest of transformers can import and work fine so i know it's there.

Any help greatly appreciated, thanks!

Hi @jakobbrown , the same is working for me with this version of packages.
transformers - '4.6.0'
torch - '1.10.0+cu102'<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
