When does the delete operation occur on tmpdir? Does it do so automatically when the function ends?
Another option is to use with, i.e.

with tempfile.TemporaryDirectory() as tmpdir:
    path = os.path.join(tmpdir, basename = os.path.basename(self.input_path) + "_desc")

though it could be essentially the same.

[YigitElma]

I think it should be cleared after the python process is terminated or the session on the cluster is closed or the system is rebooted on personal laptop, not immediately after the function call. These are the options listed on the web for "when the tmp is cleared?".

[mishapadidar]

When I ran the test, the temp directory still existed after the code ran.
