usd-core Python package doesn't include Apple Silicon support

[sleroux]

Description of Issue

I recently tried to setup the USD python tooling on a M1 Macbook pro by installing the usd-core package from PyPi but regardless of which version of Python I used I got:

ERROR: Could not find a version that satisfies the requirement usd-core==20.11 (from versions: none)
ERROR: No matching distribution found for usd-core==20.11

The only thing I can think of that would be causing this is that USD currently doesn't offer a build of the C++ bindings for the Python library on Apple Silicon.

System Information (OS, Hardware)

MacOS Monterey 12.1, 2021 M1 Macbook Pro (Apple Silicon)

Package Versions

usd-core 21.11

Hi @sleroux, as you suspected we currently do not publish native M1 builds of the usd-core package on PyPI. However, you should be able to use the published packages via Rosetta on your MacBook. This worked for me on an M1 machine running macOS 12.2.1:

# Start a new shell under Rosetta and confirm we're in emulation mode
$ arch -x86_64 zsh
$ arch
i386

# Install usd-core from PyPI
$ python3 -m pip install usd-core

Closing this out, but please reopen if you encounter more issues with this. Thanks!

Actually, let me leave this open to track potentially adding a native M1 usd-core package in the future.

It seems like we should be able to set up a 'universal binary' build of the package on Azure and publish that to PyPI, but I'm not 100% certain that's possible or what that might look like. Maybe someone with more experience with this can chime in?

It looks like this may be fixed by 56e59a8. Will the new universal2 package start being published when there is a new release?

@jakedouglas Yes, it will be. The wheel for the current dev branch is available from Azure for testing if you'd like to give it a spin: https://dev.azure.com/PixarAnimationStudios/USD/_build/results?buildId=2248&view=artifacts&pathAsName=false&type=publishedArtifacts
