       error: Python version mismatch in 'python3.11-openusd-24.05':

       The Python derivation 'python3.11-openusd-24.05' depends on a Python derivation
       named 'python3.12-materialx-1.38.10', but the two derivations use different versions
       of Python:

               'python3.11-openusd-24.05' uses /nix/store/hyppxdhgqx7nbg394j97yhmi6vizl074-python3-3.11.9

       Possible solutions:

         * If 'python3.12-materialx-1.38.10' is a Python library, change the reference to 'python3.12-materialx-1.38.10'
           in the buildInputs of 'python3.11-openusd-24.05' to use a 'python3.12-materialx-1.38.10' built from the same
           version of Python

         * If 'python3.12-materialx-1.38.10' is used as a tool during the build, move the reference to
           'python3.12-materialx-1.38.10' in 'python3.11-openusd-24.05' from buildInputs to nativeBuildInputs

         * If 'python3.12-materialx-1.38.10' provides executables that are called at run time, pass its
           bin path to makeWrapperArgs:

               makeWrapperArgs = [ "--prefix PATH : ${lib.makeBinPath [ materialx ] }" ];

I did a little searching and I think the issue comes from the blender package, or blender-hip for me. Removing it from my packages got rid of that error, but now I'm getting a new one.

Issue could be related to this #325682

Either way,
Ma, someone messed with the Python again!

[ShaddyDC]

Both plain openusd and blender work for me on master (nix build .#openusd, nix build .#python3Packages.openusd and nix build .#blender).

It's possible that this requires #325292 to work properly, which hasn't propagated to nixos-unstable yet?

The python 3.11 version does indeed fail:

I think I'll leave that to people who understand how python derivations properly work here.

[ShaddyDC]

Probably. Sip4 has explicitly disabled python 3.12, though I don't know why: 544c197
There's some related discussion for cura in #186570

It looks like both the packaged version of cura and sip4 are pretty old. Maybe it's worth removing them from whatever depends on them if that's simple.

[SuperSandro2000]

though I don't know why

See the comment: relies on distutils

distutils was dropped in Python 3.12.
