    from collections import Callable
ImportError: cannot import name 'Callable' from 'collections' (/usr/local/lib/python3.10/collections/__init__.py)

Reason: collection.Callable moved to collection.abc.Callable in 3.3, deprecated in 3.7, removed in 3.10.
Deep reason: Requirement github3.py<1.0.0 is too old.
