Nightly feedstock build failed

Nightly feedstock build failure for tiledbsoma-feedstock at https://dev.azure.com/TileDB-Inc/CI/_build?definitionId=43&_a=summary

[jdblischak]

The nightly feedstock builds that run tests all failed. Specifically the import test failed for the Python 3.9 environment.

Fortunately/frustratingly I already started troubleshooting the source of this problem yesterday. anndata 0.11.0 dropped support for Python 3.9, but the feedstock PR was automerged before I could fix it.

@jdblischak I think that our Python 3.9 things will simply "find" anndata 0.10 .....

You're half right :-) I just checked. anndata is pinned <0.11 in the UDF image but not the notebook image

[johnkerl]

No I mean that (for pip at least) when a Python 3.9 system tries to install anndata >= 0.10.1, the most recent version 0.10.9, and no 0.11.anything will even be offered. And I thought it was similar for Conda; I may be mistaken ...

pip yes, conda no

mamba create --yes -n py39 -c conda-forge python=3.9
mamba activate py39
mamba install --dry-run -c conda-forge anndata=0.11
##   + anndata                 0.11.0  pyhd8ed1ab_0            conda-forge      112kB
pip install --dry-run anndata==0.11
## ERROR: Ignored the following versions that require a different python version: 0.11.0 Requires-Python >=3.10; 0.11.0rc3 Requires-Python >=3.10

But once I fix the conda recipe and conda-forge metadata, then conda will behave the same (and the nightlies will be fixed)

[johnkerl]

I fully expect an explicit request for anndata=0.11 to fail on a Python 3.9 system. Absolutely.

I did expect anndata >= 0.10.1 to succeed on a Python 3.9 system (in pip or conda) ...

Should be fixed by https://github.com/conda-forge/anndata-feedstock/pull/45 and https://github.com/conda-forge/conda-forge-repodata-patches-feedstock/pull/902

[johnkerl]

Awesome, thanks @jdblischak !! :)
