I'm confused about the failing runs. I removed the numpy import but this job is still saying it can't find numpy (line 53 of the log). Also this job is complaining about Use "list[T]" instead of "typing.List[T]" (PEP 585 syntax) but I don't use typing.List[T] anywhere.

According to mypy_primer, this change has no effect on the checked open source code. 🤖🎉

The issue is that the package you're trying to add stubs for is a little broken. It has a runtime dependency on numpy, but doesn't declare that dependency in e.g. its setup.py

I also can't find a canonical source for the PyPI package you posted, and it hasn't been updated in half a decade, so not sure how you'd get that fixed.

https://github.com/swatbotics/apriltag has some version of the code, but says

Please note: I am not the maintainer of the pypi package listed at https://pypi.org/project/apriltag/ – GitHub issues filed here reporting problems with that package will be summarily closed. Sorry, I don't have time to support someone else's unofficial package.

If I were you, I'd consider forking the package and adding types to it directly

Thanks for your quick reply!

Since there was no repo, I just downloaded the source code from https://pypi.org/project/apriltag/#files

If there's no way to get this to work, should I close the pull request?
