Python 3.13 issue

[blopker]

Heyya, I'm trying to update my site to Python 3.13.1 from 3.12 and the mrml Python package is giving me an error on install:

Maybe py03 needs to be updated?

Thank you!

Here's a minimal Dockerfile reproduction:

FROM python:3.13-slim-bookworm

RUN pip install mrml

Run docker build .

Is there anything I can do to help with this issue? Python is on 3.13.1 now, a lot of projects tend to do their minor updates after the first patch version is released.

I think not doing the nogil work is fine for now since there's not many benefits now and I don't think many projects use it.
