Hi! This is the staged-recipes linter and your PR looks excellent! 🚀

[conda-forge-admin]

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/ragatouille/recipe.yaml) and found it was in an excellent condition.

@conda-forge/help-python, ready for review!

[ocefpaf]

Why? This will force all downstream packages to disable it too. If there is a problem that we can fix, let's fix it. If not, we should document the problem and open an issue.

[moritzwilksch]

True. The original reason was:

 │ │ colbert-ai 0.2.21 requires git-python, which is not installed.
 │ │ colbert-ai 0.2.21 requires ninja, which is not installed.

which errors even though I provided them as run dependencies in the colbert-ai-feedstock:

https://github.com/conda-forge/colbert-ai-feedstock/blob/a76ce8c4437fdf05cf1e81f36777ead2745f2169/recipe/recipe.yaml#L27-L29

For git-python, I'm not sure whether gitpython is a drop-in replacement:

https://github.com/stanford-futuredata/ColBERT/blob/7067ef598b5011edaa1f4a731a2c269dbac864e4/setup.py#L25

But the git-python on pypi looks sketchy:
https://pypi.org/project/git-python/

[ocefpaf]

Can you open an issue in https://github.com/conda-forge/colbert-ai-feedstock/blob/main/recipe/recipe.yaml#L41 about that? Also, please add a comment here so we don't forget.

[moritzwilksch]

I just created that feedstock myself last week. Happy to fix that but do you have an idea how? Ninja is a run dependency and I'm not quite sure what to do about git-python

[ocefpaf]

Fix what you can and open issues/notes for the rest. The git-python vs gitpython probably need some metadata fix upstream, not only the recipe.

[moritzwilksch]

Alright, I fixed the issues related to colbert-ai:
conda-forge/colbert-ai-feedstock#1

• gitpython is incorrectly required by upstream (PR to fix upstream here, I patched it in the feedstock)
• ninja is required because colbert-ai uses torch's ability to load and JIT cpp modules (see here) but since the ninja package only contains a ninja binary in bin/ninja it fails the pip check

Last problem is faiss-cpu as a direct dependency. Could this be a similar problem where the package is not recognized as a python package?

No idea. Sorry, my packages are usually quite "vanilla pure python." If that is the case we should add a comment about it and skip pip-check for now.
