Improve the band-aid solution for seg faults and the static TLS error

[eladsegal]

I kept getting "ImportError: dlopen: cannot load any more object with static TLS" and segmentation faults.
At first, it seemed the cause is the import of sklearn in the AUC metric. After adding sklearn import before everything else, I didn't get the static TLS error anymore, but continued getting seg faults which came from imports from transformers.
Adding a transformers import before all other imports helped with both errors.

I don't understand why this happens but I'm glad we have a work-around. Thanks!
