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

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

For recipe/meta.yaml:

• No valid build backend found for Python recipe for package netcdf4 using pip. Python recipes using pip need to explicitly specify a build backend in the host section. If your recipe has built with only pip in the host section in the past, you likely should add setuptools to the host section of your recipe.

I'm hoping the OSX-64 python 3.12 MPICH error is just a temporary one that will go away with a rerun. (But that's still frustrating if so!)

Thanks @ocefpaf. I don't know if it's a memory issue or what but pretty annoying!
