watchmedo not working on M1 Mac

Hey Guys,

We have two mac Big Sur, one intel and the other M1. watchmedo is not working when called from the M1.

test_app| Inotify._raise_error() test_app | File "/usr/local/lib/python3.8/dist-packages/watchdog/observers/inotify_c.py", line 405, in _raise_error test_app | raise OSError(err, os.strerror(err)) **test_app | OSError: [Errno 38] Function not implemented** test_app_valid exited with code 1 test_app exited with code 1

watchmedo is being called inside a docker image.

Our compose.yml command: command: watchmedo auto-restart -d test_app/test_app_valid/ -p '*.py' -- python3 -m debugpy --listen 0.0.0.0:20000 -m test_app. test_app_valid

I’m having a similar issue with the watchdog library (not watchmedo):

Traceback (most recent call last):

    raise OSError(err, os.strerror(err))
OSError: [Errno 38] Function not implemented

The base image is python:3.9-slim.

If you have the flexibility of using an arm64 based container, this is also another solution to this problem. The docker issue is with inotify under the emulation mode only. If you have the option to use an arm based container, watchdog should work normally.
