beartype error

[yxc8]

Hi,

I get the following error complaining about beartype import, when running !pipenv run python3 -m src.testset --train-set train.jsonl --days 2 --output-path 'out/' --seed 42

Any suggestion on how to fix this?

Thanks!

Following up on this, it seems like using python3.10 instead of python3.9 avoids this problem. Not sure why the python3.9 won't work.

Hi @yxc8, thanks for your feedback! This issue is a known CPython issue (#42965) resolved in 3.9.2. See this beartype issue for more context. As you have already discovered, the solution is to use a Python version >= 3.9.2. I would like to integrate this minimum version requirement for our Python version into our Pipenv, but unfortunately, this is currently not supported.
