| Hugo | Thanks connor (he/him) (UTC+2) .
I can now launch the triton test.
However, when attempting to launch tests on the unstloth library, nix builds Torch for Python313 instead of Python 312.
Torch is not supported on Python 3.13 yet - it still attempts to build however which confuses me.

HIP kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing AMD_SERIALIZE_KERNEL=3
