run_mlm_no_trainer.py requires accelerate but not in requirements.txt
I just installed Transformers 4.9.0 as I'm really excited to investigate the tokeniser free CANINE model.

I noticed that the `examples/pytorch/language-modeling/run_mlm_no_trainer.py` script requires the `accelerate` library but that doesn't appear to be included in `examples/pytorch/language-modeling/requirements.txt` or the main `setup.py`

Thanks for flagging, I added those to all examples in the PR mentioned above!<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
