Theoretically this supports NumPy 2 and Python 3.13 but we first need to migrate h5py.

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.

Python 3.13 depends on conda-forge/h5py-feedstock#148

Does building complete?

I'm wondering if we can at least add a test to stay aware of things like:
#296 (comment)

Does building complete?

For the non-CUDA variants, it works. I have cancelled the jobs as I realised that the CUDA jobs just hang at the ./configure step and would only be a waste of resource. I now what has to be fixed with CUDA to compile (same fixes as in jaxlib) but I'll probably do them next week.

Is there anything in #296 (comment) which we could test on a non-CUDA system?

I really tried hard to read your comments on the jax repo to see if it was something I could fix myself.

I was hoping we could "force" some compilation (but not execution). That said I don't know enough about the workings of tensorflow for this.

AFAIR 2.18 is also the first version to support numpy 2.0

[xhochy]

I have both added locally and will push them with some fixes in the next days. If anyone is eager to be faster, happy to see it but let me know 🙃

[hmaarrfk]

would you be willing to push your fixes? curious if we can get the protobuf going with 2.18.0 now that it is release.
