I want to build a wheel file for a package, but get this problem below:

ERROR Backend subprocess exited when trying to invoke build_wheel

  • Building wheel from sdist

  • Installing packages in isolated environment… (–extra-index-url https://download.pytorch.org/whl/cu118, ninja, setuptools, torch==2.0.0+cu118)

You would need to check which file type in pyronn is unknown as the error seems to come from this 3rd party library, not PyTorch itself.
