  There is also watchexec[1]. I like the fact that is it shipped as a sinle binary, so it's pretty easy to distribute [1]https://github.com/watchexec/watchexec

  Awesome library, I use it in ayu (https://github.com/Zaloog/ayu) to watch for changes in test files, to automatically rerun those tests.

  There are some big caveats to this approach. Note “Known Problems” for the library. Particularly, you need to use a polling backend for network / VM filesystems. I didn’t see any notes for the Python library and the fact that notify is still telling you this makes me suspect it will just fail to work in those cases.
