Pytorch-tpu runbook issue with dependencies

Hey folks,

I used to be able to do this, but something new must’ve integrated circa Dec 8th (that the setup scripts at the below link pull automagically) and broke things for me, resulting in errors.

I am following instructions:

During the setup phase, I get a 3 iterations of this message:

ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
transformers 4.35.0.dev0 requires regex!=2019.12.17, which is not installed.
transformers 4.35.0.dev0 requires tokenizers<0.15,>=0.14, which is not installed.

Is there a way to go back to an earlier release date (i.e. say December 7th) ?

Wondering what am I missing ?

Many thanks for any suggestions!
