ImportError: cannot import name 'Mapping' from 'collections'

[markfansjsu006]

I am using python 3.10 and I am having trouble training data when testing the installation.

Since python 3.10 Mapping is moved to collections.abc, quick fix would be to change:

from collections import Mapping, defaultdict

to

from collections import defaultdict

try:
    from collections.abc import Mapping
except ImportError:
    from collections import Mapping

However, I don't know if there maybe is some better way to handle this.
