Overall looks fine, but thereare many meaningless changes - i.e permutations of import order, what does it bring?

This is due to isort library isort is a Python library to sort imports alphabetically and automatically separated into sections and by type. . You can look here for more information why this is good idea to use.

I propose not to apply changes to the contrib files from LM-Eval harness. This is to be able to make an easy claim that we did not tinker with that testing code.

Good point. Excluded LM-eval-harness folder from isort and black.
