clusters plotter is incompatible with pytorch on windows because of 'control' library

[haesleinhuepf]

When installing napari-clusters-plotter and pytorch in the same conda environment, pytorch doesn't work unfortunately. The problem is that the library control breaks pytorch. control is installed because the clusters-plotter installs finesse, which depends on control. The issue only comes when installing the clusters-plotter using mamba or conda. The pip installation is fine.

finesse is listed under requirements on conda-forge, but not in requirements.txt or setup.py. I can confirm that installing it via pip doesn't cause the issue.

To reproduce set up an environment like this:

mamba create --name test10 python=3.9 napari-clusters-plotter -c conda-forge

mamba activate test10

mamba install pytorch torchvision torchaudio pytorch-cuda=11.7 -c pytorch -c nvidia

Run this python script:

import torch

Error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\haase\mambaforge\envs\test10\lib\site-packages\torch\__init__.py", line 122, in <module>
    raise err
OSError: [WinError 182] The operating system cannot run %1. Error loading "C:\Users\haase\mambaforge\envs\test10\lib\site-packages\torch\lib\nvfuser_codegen.dll" or one of its dependencies.

Figuring out dependencies

I used conda-tree to figure that out:

mamba create --name bio393 python=3.9 devbio-napari -c conda-forge
mamba activate bio393
mamba install -c conda-forge conda-tree
conda-tree whoneeds control

finesse

conda-tree whoneeds finesse

I will make a new release on pypi and conda-forge to remove the finesse dependency. In case anybody thinks finesse should stay, please report issues.

I don't even know that library and since it is not in the pip dependencies I'm fine with removing it
