The version of Django in that project is not compatible with Python 3.10.

You’ll need to either

  • use an older version of Python (Django 2.x, as used by that project supports up to Python 3.7)
  • or preferably do the work to make the project compatible with a newer version of Django. At the time of writing, Django 4.0 was just released a few days ago. You can then contribute those changes back to the project as a pull request.

I think that official deprecation warning (in Python pre 3.10) explains everything.

Python 3.8.10 (default, Mar 13 2023, 10:26:41) 
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import collections
>>> collections.Iterator
<stdin>:1: DeprecationWarning: Using or importing the ABCs from 'collections' instead
of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working
<class 'collections.abc.Iterator'>
