Congratulations! You've made it this far! You're not quite done yet though.

Once merged, your PR is going to appear in the release notes with the title you set, so make sure it's a great title that fully reflects the extent of your awesome contribution.

Once you're done, someone will review your PR shortly (see the section "Who can review?" below to tag some potential reviewers). They may suggest changes to make the code even better. If no one reviewed your PR after a week has passed, don't hesitate to post a new comment @-mentioning the same persons---sometimes notifications get lost.

_The documentation is not available anymore as the PR was closed or merged._<|||||>I'm sorry I overlooked mistakes in those two sentences. It's true those are not fixes, though the first one is not gramatically correct anyway.

Do as you wish to fix those, I'll make sure to stay very far away form the deepspeed file in the future.<|||||>I tried revert, but I thought it'd magically resume this PR and it didn't, so it'd be a bad workflow. So if I have to make a new PR, it's much simpler to just do a new PR with just the fixes: https://github.com/huggingface/transformers/pull/15355
