Conda: 4.10.3 Python: 3.9.7 OS: Windows 10

Hi, I have made a new environment and tried installing the napari ilastik plugin atop napari with the following commands.... 

conda create -n ilastik_napari_test
conda activate ilastik_napari_test
conda install -c conda-forge napari
conda install -c ilastik-forge napari-ilastik

However, this returns the following error

(ilastik_napari_test) C:\Users\U062951>conda install -c ilastik-forge napari-ilastik
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Any advice how to proceed with installation? Thanks!

Currently, this plugin requires Python 3.7 due to a dependency in the ilastik-forge channel. When you did conda install -c conda-forge napari,conda installed napari and Python 3.9 into your environment, that's why conda install -c ilastik-forge napari-ilastik fails (it seems that conda doesn't know how to downgrade Python).

We are working on bringing our dependencies up to date with recent Python versions, it should be fixed soon. In the meantime, don't explicitly install napari into a new environment (that is, skip conda install -c conda-forge napari).

Thanks for feedback. I have skipped conda install -c conda-forge napari as you said, and specified python=3.7 but still get an install error

Commands... 

conda create -n ilastik_napari_3pt7 python=3.7
conda activate ilastik_napari_3pt7
conda install -c ilastik-forge napari-ilastik

Error...

Perhaps i need to specify an earlier napari version to install?

@mezwick I have the same problem. Did you manage to get this installed? If so could you let us know how? Thanks!
