Temporarily running the whole suite on 3.12 only

[ricardoV94]

All tests passed on 3.12: https://github.com/pymc-devs/pymc/actions/runs/8379574806/job/22948777361?pr=7203

Going to revert so we still run some of the tests on 3.9

[maresb]

I didn't realize that we only test Python 3.9 with Windows. That should be fine 99% of the time, but for those crazy edge cases maybe we want some sort of pre-release workflow that runs the whole matrix?

[maresb]

Probably out-of-scope for this PR, but is this ignore still necessary? The corresponding issue is closed.

Also minor nit, it'd be nice to copy the style for the last comment/argument and inline those two preceding comments.

[ricardoV94]

Removed, thanks for pointing it out

[ricardoV94]

That should be fine 99% of the time, but for those crazy edge cases maybe we want some sort of pre-release workflow that runs the whole matrix?

I'm inclined not to :)

[maresb]

My suggestion was to also inline this. (Turn all warnings into errors for this module)

[maresb]

But now I'm getting to the nittiest of nits. :)

[ricardoV94]

But that's why the filterwarnings is there in the first place? Without the temporary filters it looks like

# Turn all warnings ...
pytest.mark.filterwarnings("error")

[maresb]

Do I misunderstand how filterwarnings works? The arguments get stacked, right?

pytestmark = pytest.mark.filterwarnings(
    # Turn all warnings into errors for this module
    "error",
    # except those related to https://github.com/arviz-devs/arviz/issues/2327
    "ignore:datetime.datetime.utcnow():DeprecationWarning",
)

[ricardoV94]

My point is that, without the temporary ignores, it makes more sense to have the comment above the call. That also explains why the call is there in the first place.

# Turn all warnings ...
pytest.mark.filterwarnings("error")

Makes more sense than

pytest.mark.filterwarnings(
  # Turn all warnings ...
  "error",
)

[ricardoV94]

I'm gonna take the nitpick hint and merge as is
