Mypy pre-commit tests keep failing

[Alex-JG3]

🐛 Bug

I have set up a developer environment by following the contributing guide. I made a small change to albumentations\augmentations\geometric\functional.py but the pre-commit mypy tests keep failing.

To Reproduce

Steps to reproduce the behavior:

1. Fork the repo.
2. Set up the environment by following the contributing guide.
3. Add print("Hello, world!") to line 18 in albumentations\augmentations\geometric\functional.py
4. Execute git add albumentations\augmentations\geometric\functional.py
5. Execute git commit -m "Test change"

The following error message should be produced.

git commit -m "Test commit"

Executing python3 -m pip install types-PyYAML or mypy --install-types do not help, the same error message is produced.

Expected behavior

All pre-commit tests should pass.

Additional context

The following issue might be relevant python/mypy#10632.

I have been able to solve the issue by adding additional_dependencies: [ types-PyYAML==5.4.12 ] to the following line.

albumentations/.pre-commit-config.yaml

Line 23 in 5a3b230

Are you sure that you are using the same interpreter as pre-commit? Because I see that you have installed types-PyYAML, but pre-commit can not find it.

[Alex-JG3]

I think you are right. Is there are way to see which interpreter pre-commit is using? Or is there a way to change the interpreter that pre-commit is using?
