[x] Closes #9664

Missing libraries:

dask: dask-expr depends on pyarrow, which will support 3.13 starting with pyarrow>=18.0
pydap: depends on webob which uses the removed cgi stdlib (see https://github.com/pydap/pydap/issues/319#issue-2274388164 in the "out-of-scope" section)
numba: as usual will take some time to support it (and thus we can't test numbagg and sparse)

Interestingly it's conda that you can't install along with python=3.13, but cftime, pandas, and possibly h5py also raise errors (I can't reproduce that locally, though). So I guess we'll have to revisit this in a couple of weeks.

Is there a reason we are installing conda? For the output of conda info and conda list? There is a micromamba info and micromamba list output in the Setup micromamba step which we could refer to instead.

keewis commented 3 weeks ago

we use conda to call conda info -a, which contains information micromamba info does not include (and I don't know whether micromamba info -a exists). In theory we could use mamba info -a as well, but that also doesn't provide packages for python 3.13.
