Support for ARM architecture for M1 Mac (OS X)

[guigrpa]

Sorry if this has been asked elsewhere (I couldn't find it). Are there plans to support ARM binaries for M1 Macs?

maybe it's the question of esmpy which depended by xesmf.

@rokuingh Are there plans for ESMpy to be built on ARM?

[rokuingh]

@huard we don't currently have plans for this, but I added a feature request. Unfortunately the ESMF support repo is private but someone will contact you when this issue is prioritized.

[rokuingh]

@huard a port for ARM64 has been added to the upcoming patch release 8.3.1, this will show up in conda-forge when it is available.

[huard]

@guigrpa Do you want to give it a try now ?

[guigrpa]

I will definitely try it out, probably when I come back to this feature of our project in a month or so. Thanks!

Looks like ESMF ARM support has been merged https://github.com/conda-forge/esmf-feedstock/commit/bfdd28c64db029292bdfe19c9dbcba7760c161ed

@guigrpa Any news on this ?

Just tried to install right now on a M1, and I got the following results:

$ conda install xesmf

This is issue #212, i.e. a breaking change in ESMpy 8.4. xESMF was adapted to this change in v 0.7.

Is there a reason v 0.3 was installed here, seems quite vintage ?

ARM architecture seems supported in ESMpy 8.3.1, as hinted at above, you could try to downgrade ESMpy if upgrading xESMF fails for now.

[philippemiron]

Yeah, I'm not sure why it installed such an outdated version in my main environment. I've created a new one for xesmf and it's working. Thanks for the fast answer :D

[huard]

Thanks for the update!
