Quality checks are failing on `main`, but are unrelated to this PR @amyeroberts. We'll rebase once fixed by https://github.com/huggingface/transformers/pull/30932!

I think I messed up the merge! Whilst rebasing

I synced my fork with transformers followed by 

1. `git pull`
2. `git checkout <BRANCH>`
3. `git rebase main`
4. `git push --origin force`

Where did I go wrong lol?

> * `git pull`
> * `git checkout <BRANCH>`
> * `git rebase main`
> * `git push --origin force`

@Vaibhavs10 A few questions to try and figure out what happened: 
* `I synced my fork with transformers`: How did you do this? Which branch was "synced"? 
* `git pull` on which branch are you pulling to and from? What is your default pull settings i.e. does running `git pull` do a merge or a rebase? 
* `git rebase main` I'm guessing this was on the feature branch? 

A few things might have happened. I suspect the culprit for any unexpected behaviour here is the pull, as it might have introduced merge commits. Working on my feature branch, these are the steps I normally take: 

```
git fetch upstream main
git rebase upstream/main
# My gitconfig settings will always push to the current branch by default
git push -f 
```

You don't technically need to update your main branch, you just need to fetch the most recent commits from upstream. 

The git history looks like what happens if one pulls then force pushes. The good new is, this can be rectified by rebase on main (no pulls!) and force pushing again. 

Thanks @amyeroberts - I synced via `git fetch upstream main` too. @sanchit-gandhi pointed out that I used `git push --force origin` instead of `git push --force origin` - hence the commits.

I followed your advice and that seems to have fixed the conflicts.

Wow! git is hard - thank you for being so patient and explaining this to me.

You both are the best! 🤗

Note: the code quality checks now pass haha!

@Vaibhavs10 Do you have permission to merge? If not, I can do it for you 

Nope nope - would be great if you can merge. 🤗

Thanks again!
