I got this error when getting mT5 model. Can anyone help?

Coming at this late, but I just wanted to point out that this error message includes two suggestions:

_Attempted to read a PyTorch file with version 3, but the maximum supported version for reading is 2. Your PyTorch installation may be too old._

and

_If you tried to load a PyTorch model from a TF 2.0 checkpoint, please set from\_tf=True._

The second doesn’t seem applicable, but I’d be curious to know if just updating PyTorch fixes the issue.

I updated my torch but unfortunately that does not fix the issue.
