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 (recipe/recipe.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/recipe.yaml:

• ℹ️ noarch: python recipes should usually follow the syntax in our documentation for specifying the Python version.

  • For the tests[].python.python_version or tests[].requirements.run section of cuda-python output, you should usually use the pin python_version: ${{ python_min }}.* or python ${{ python_min }}.* for the python_version or python entry.

• If the package requires a newer Python version than the currently supported minimum version on conda-forge, you can override the python_min variable by adding a Jinja2 set statement at the top of your recipe (or using an equivalent context variable for v1 recipes).
