Hi,
The error is caused because `aqt/models.py` refers to
`collections.Callable` instead of `collections.abc.Callable`. The old
version of Anki was probably for an older Python where `Callable` was
not moved yet. I did not find any other problematic import of
`collections`.
The following is a diff of the change that I made in-place. I did not
want to start a full Anki build from ports:
