I believe the problem is in setup.py install_requires.

transformers version must be new enough to have 'is_nltk_available'.

I think it was introduced in transformers 4.34, but I'm not 100% certain.

Heya!

Thanks for reporting this; you're very right. And I believe it was indeed introduced in 4.34.0. I'll create a PR to increment the minimum transformers version accordingly.
