> Thanks for the fix, but you may need to make that change in the `modular` file as well and run `make fix-repo` to propagate it correctly.

I updated the modular file and ran `make fix-repo`. Everything worked except for `python utils/check_pipeline_typing.py --fix_and_overwrite` and `python utils/check_docstrings.py --fix_and_overwrite` because of some torchvision error. I assume it's not a major issue.

Yeah, don't worry about that. Thank you for the PR!
