Issue

Recently ran some tests on all plugins, and this was one of the few I couldn't install. https://github.com/tlambert03/npe2/runs/5576546206?check_suite_focus=true#step:6:41

Got:

Looking for: ['napari-allencell-segmenter']

Pinned packages:
  - python 3.9.*

Encountered problems while solving:
  - package napari-allencell-segmenter-1.1.4-pyhd8ed1ab_0 requires aicssegmentation >=0.4.1, but none of the providers can be installed

Error: Process completed with exit code 1.

... but everything looks to be in order on anaconda cloud. @jaimergp, any ideas what might be going on?

The dep tree includes https://anaconda.org/conda-forge/itk-meshtopolydata/files, which doesn't have builds for Python 3.8 and above. Try using Python 3.7 in your action for now!

We can also try to fix this https://github.com/conda-forge/itk-meshtopolydata-feedstock/pull/5

Aha, thanks. That was an easy one, sorry I missed that

I only just saw this @tlambert03, am a little confused here. How can I resolve this on my end?

[jaimergp]

Support for the needed Python versions should be added here: https://github.com/conda-forge/itk-meshtopolydata-feedstock
