probability Importing ABC directly from collections was deprecated from Python 3.4 and will be removed in 3.10

Importing ABC directly from collections was deprecated from 3.4 and will be removed in 3.10. Using collections.abc is recommended. Since the project is Python 3 only it doesn't require Python 2/3 shims for the fix.

Thanks @tirkarthi. For the time being, despite not supporting py2 externally, we still need to maintain compatibility for some internal users inside Google. I agree we should eventually take care of this though, once internal py2 users have migrated completely.

I'm now getting an error with v 0.14.0 and Python 3.10.

As OP says, it should be updated to collections.abc.Sequence
