this particular line looks different with Python 3.9, since the package
is built with an automated Python 2 to Python 3 converter, which does
not seems to work correctly on 3.10 (build_py_2to3 in setup.py). Not
sure why though. Given the warning on their homepage it’s probably
safe to drop the package.

This is trivial to fix and should be

        from collections.abc import Mapping

which seems to be the only change in attrdict3, see
