Add support for Python=3.12

[valeriupredoi]

Closes #112

• Indeed basemap is the show-stopper for now (17 Oct 2023): https://anaconda.org/conda-forge/basemap/files - not even sure if there will be any basemap rebuilds anyway [Question] Is there going to be a Python=3.12 build... conda-forge/basemap-feedstock#119 - this has been sorted out
• nctoolkit is equally unsolvable https://anaconda.org/conda-forge/nctoolkit/files
• agh and I forgot about cartopy -> saw the incompatibility in ESMValCore - this too has now been sorted out, nctoolkit is the only bugger - @ledm remind me again pls, is nctoolkit a main dependency or we can make it optional?

Yeh this needs to wait, bet after Christmas it'll all be dandy

All dependencies solve for and tests pass - we have full support for Python=3.12 🥳

[valeriupredoi]

gonna revisit imminently, things are a lot smoother Py312-wise now

[valeriupredoi]

as per conda-forge/basemap-feedstock#119 and @molinav 's efforts baemap is now compatible with Python 3.12 - the only problem we now have is nctoolkit

[valeriupredoi]

@robertjwilson and myself are sort of discussing the 3.12 support for nctoolkit in here pmlmodelling/nctoolkit#111 - numba (as a dep for nctoolkit) is the blocker currently

[robertjwilson]

No worries @valeriupredoi . It looks like the release candidate for numba is Python 3.12 ready. However, "Numba is currently on a Winter Break", whatever that means. So just need to wait for them to decide to push a full release to pypi numba/numba#9197

[valeriupredoi]

cheers @robertjwilson - Winter Break sounds a bit scary - Napoleon went on such a venture in Russia and came back without an army, so hopefully they'll be back 😁

[valeriupredoi]

@robertjwilson good news, mate! numba has finally come back from winter break and some 29 hours ago they finally py312-ed themselves 🥳

[robertjwilson]

OK. Just need to wait for the gears to grind at conda-forge for nctoolkit to be available for 3.12, @valeriupredoi. Essentially, we need to wait for their system to automatically re-build geoviews, and then nctoolkit.

ya! No rush at all @robertjwilson - we needed numba to be 312-modern for another package, just wanted to drop the good news 😁

[robertjwilson]

I have finally got nctoolkit available for python 3.12 on conda forge. Let me know if everything works at your end @valeriupredoi and I will close the issue.

[valeriupredoi]

great news @robertjwilson cheers 🍺 Let me resurrect this one then

[valeriupredoi]

@ledm give this one a nod of approval pls bud, we are now modern wrt Python 🐍

[ledm]

Looks like nothing too crazy. Do you need me to test these on jasmin?

[valeriupredoi]

no not at all - if tests work then it should be fine. Cheers, bud 🍺 And cheers to @robertjwilson for his work on nctoolkit 🍺

[robertjwilson]

Excellent @valeriupredoi
