Regarding scipy-notebook:

• numba does not yet support Python 3.11.
• The current release of pytables and statsmodels do not support Python 3.11.
  • Both packages build from branch main, though.

Please, also change the python version in tests.

Thank you @benz0li and @mathbunnyru
I found one test that I have changed the python version to 3.11

[bjornjorgensen]

hmmm... it failed with some strange errors

#14 12.04 Encountered problems while solving:
#14 12.04   - package mamba-0.18.1-py310hcf12e44_1 requires python_abi 3.10.* *_cp310, but none of the providers can be installed


#15 24.31 error    libmamba Could not solve for environment specs
#15 24.31 Encountered problems while solving:
#15 24.31   - package mamba-0.0.10-py27hc9558a2_1 requires python >=2.7,<2.8.0a0, but none of the providers can be installed

But where does this old mamba come from?

[mathbunnyru]

I think micromamba is installing an old version of mamba when there are no good versions.
I beleive it's too early to start using python-3.11 in our project because we have to wait for all the dependencies to support it.

Currently, we don't have any policy on when to update the python version.
Guess a reasonable one would be to wait for both:

• all the dependencies to be available
• the first python patch release, for example, python-3.11.1 (this is to avoid many bugs, which can happen in a major release)

[bjornjorgensen]

@mathbunnyru Yes, that it a good idea.

[mathbunnyru]

I've converted this to a draft, because it's unlikely we will merge this really soon. I think we can try to close/reopen this PR in a month or so to make sure our images build fine.

[EwoutH]

Statsmodels 0.13.3 is released, with Python 3.11 wheels!

[bjornjorgensen]

@EwoutH yes, but When should you upgrade to Python 3.11? so will wait for 3.11.1 and everything else that we have are supported in python 3.11
