Github action - Tests cleanup fails on `rm -rf`: Directory not empty

[hchau630]

Description

I'm using cibuildwheel's Github action to build manylinux2014_x86_64 wheels for my Pytorch C extension. I added the line CIBW_TEST_COMMAND: pytest {project}/tests in my workflow file to perform tests after the build has succeeded. The tests pass with no problem, but the job sometimes fails at the end on the command rm -rf /tmp/tmp.mXcluW4Jpi with the message rm: cannot remove ‘/tmp/tmp.mXcluW4Jpi/venv/lib/python3.12/site-packages/sympy/core’: Directory not empty I'm not sure why this is happening.

I have found that this issue can sometimes be fixed just by re-running the job, though not guaranteed.
