Python 3.10 broke compatibility with old versions of some libraries (some of them are very popular, like setuptools).
This provides a monkeypatch function that restores the compatibility shims removed in Python 3.10
Installation:
$ pip install fixcollections
Usage:
import fixcollections
fixcollections.monkeypatch()
from setuptools import setup
# etc etcIf you see this exception, you either need to do this monkeypatching or migrate to newer version of your library (like setuptools):
