import error with python-3.8.1 involving pyinotify.cpython-38.pyc

[agouaux]

After installing this module into python-3.8.1, when I try to import it, I get the following error:

$ python -m pyinotify -v /tmp
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/runpy.py", line 184, in _run_module_as_main
    mod_name, mod_spec, code = _get_module_details(mod_name, _Error)
  File "/usr/local/lib/python3.8/runpy.py", line 154, in _get_module_details
    code = loader.get_code(mod_name)
  File "<frozen importlib._bootstrap_external>", line 911, in get_code
  File "<frozen importlib._bootstrap_external>", line 580, in _compile_bytecode
ValueError: bad marshal data (unknown type code)

$ python --version
Python 3.8.1

However, after I delete the following file, it works.

# rm -f /usr/local/lib/python3.8/site-packages/__pycache__/pyinotify.cpython-38.pyc

$ python -m pyinotify -v /tmp
