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) and found it was in an excellent condition.

@conda-forge/help-osx-arm64 I looked at the builds, but couldn't decipher what was going on here. Because the jaxlib wheels are being copied directly from PyPI (that's what I remember), could it be that the wheels, which are pre-compiled, aren't compatible? If so, we might have to wait, perhaps, for XLA and then jaxlib to be compiled?

[erykoff]

Looking at the source, there's a chain of pre-compiled x86 binaries that go into jaxlib, so this isn't something we can directly make arm64 compatible.

We should probably switch this to a from-source build. https://jax.readthedocs.io/en/latest/developer.html#building-jaxlib-from-source gives the impression that this may not be too complicated.

@xhochy building from source is a bit of a pain. @ocefpaf tried it a while ago, but it didn't really work out. That said, I'm game to try again. @ocefpaf, do you have handy any notes for building jaxlib from source that I could study?

Things changed a lot from the last time I tried (2 years ago!?). We should definitely try again.
@xhochy is that something you are interested in tackling? I have to confess I don't have much free time lately for non day-job work.

[xhochy]

This possibly falls into my day job category but not super high in the priority, so I might get to this but not in the next 1-2 weeks.
