I spent a whole night to address the dependencies problems and almost lost my mind. This answer saved my life. Appreciate!

Thanks for this! Also curious how you worked this out - I've spent a whole day trying to figure this out!

I was dreading the thought of having to dive into this issue with faulthandler and meticulously cross referencing dependencies with a working version....but this post just saved my night. Thanks @boy2000-007man

This seems like a new pytorch v1.4.0 incompatibility issue with the latest huggingface releases. I'm assuming this may have been missed due to the focus on v1.5.0 support, but it seems like many people cannot make the jump to cuda 10.2/pytorch 1.5.0 currently, so this seems like a pretty big headache that should be addressed.

Closing this as solved by #5418

Cf #8199 we will remove the hard dependency on sentencepiece (replaced by the tokenizers library) in a coming release, probably end of next week.
