Thanks for iterating!

For the failing tests, running make fixup and pushing the changes should resolve

[JINO-ROHIT]

Exception: Found the following copy inconsistencies:

• tests/models\roc_bert\test_tokenization_roc_bert.py: copy does not match models.bert.test_tokenization_bert.BertTokenizationTest.test_is_whitespace at line 167
  Run make fix-copies or python utils/check_copies.py --fix_and_overwrite to fix them.
  make: *** [Makefile:38: repo-consistency] Error 1

I get this error but i tried running both commands, still gives the same error, how to resolve this? @amyeroberts

There's something funny going on with the formatting here - files like src/transformers/models/bigbird_pegasus/modeling_bigbird_pegasus.py shouldn't be modified when calling make fixup.
and you shouldn't need to run make fix-copies for this PR.

In your environment, make sure you have all of the necessary formatting libraries with pip install -e .[testing]. Once that's done, I'd undo the formatting changes to the unrelated files and then try running make fix up again

@amyeroberts ive recreated my env, can you help me out with undoing the formatting files?
