I’m using the library from conda-forge. Downgrading from 6.0.0-pyhd8ed1ab_0 to 5.6.2-pyhd8ed1ab_0 fixes the issue.

Thanks, I think the issue is mostly clarified. Either need to update pydantic to above 1.9 (maybe below 1.9 works too?) or downgrade inflect to e.g. 5.6. I use conda and unfortunately it let’s me update only to pydantic 1.9, but let’s me downgrade inflect to 5.3, and everything seems to work fine then. Good enough for me.

In fact, tests pass on pydantic 1.9.1.
