PySide2 distribution not found on Mac

[kwokcb]

Issue

I'm trying to install on a Mac M2 running Ventura 13.2.1. (Either directly from PyPi or a local build). This is with Python 3.10.9 installed.

Wheever I try to install I get this error:

INFO: pip is looking at multiple versions of quiltix to determine which version is compatible with other requirements. This could take a while.
ERROR: Could not find a version that satisfies the requirement PySide2>=5.12 (from quiltix) (from versions: none)
ERROR: No matching distribution found for PySide2>=5.12

I tried installing PySide2 explicit with no luck as well.

ERROR: Could not find a version that satisfies the requirement PySide2 (from versions: none)
ERROR: No matching distribution found for PySide2

I assume I have something set up incorrectly ?
Thanks for any help to resolve this.

@kwokcb I think this is because there isn't a PyPi package of PySide2 for Apple Silicon. What I did was switch my shell to use x86 via Rosetta2 with arch -x86_64 /bin/zsh and then with a universal build of Python (i.e. not the Python that's installed using miniconda) pip installed QuiltiX. Once the environment was all x86 everything installed and ran as expected.

@kwokcb / @eric-with-a-c the real fix for this would be to upgrade QuiltiX from PySide2 to PySide6! Does anyone know if that is in the roadmap? 🙏

Running into the same issue here. The workaround of switching architecture as described above kind of works, but additionally requires building USD again with x86 support too.

Hey!

This is definitely something on our mind for 2024 as we want to stay on the VFX reference platform: https://vfxplatform.com/

As a lot of other projects will have to do this transition next year I would love to hook onto their solutions to this problem. One way forward could be to transition to qtpy like other recent projects in this space are using: https://github.com/BigRoy/usd-qtpy/blob/main/pyproject.toml#L26C6-L26C10

I believe OpenUSD can use either PySide2 or PySide6 for usdview

[manuelkoester]

Oh interesting. Seems like usdview created its own sim around these versions.
Currently we are a bit constrainted to what NodeGraphQt will be doing as we rely on it very heavily for basically all of our UI.

[manuelkoester]

But there are several open issues on it and even an open PR, so I don't worry too much that this will be a tough issue to solve. But it will still be quite time extensive and I would not want to move forward before NodeGraphQt has not upgraded.

Will close in favor of: #57

Also for anyone interested in this thread; This is now done with v0.6.0 🎉
