Python 3.10 release?

[sroet]

Background: PyEmma is a testing dependency for a package I maintain. We are trying to enable tests on python 3.10.

Currently when trying to run conda install pyemma in a python 3.10 environment, this fails with:

conda install pyemma
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found

Your python: python=3.10

reproducer (assuming you have conda-forge added as a channel in conda):

conda create -n test python
conda activate test
conda install pyemma

What would be required for PyEMMA to be build on python 3.10 (other than the conda-forge bots doing their magic)?

Installation with pip works so I guess it is indeed a matter of conda-forge bots doing their magic. Perhaps there are one or more dependencies that are not yet python 3.10 capable, I will have to check.

At the very least bhmm has to be updated, too. Or we replace the pyemma implementation with deeptime. :slightly_smiling_face:

[marscher]

I'd replace it.

[clonker]

I agree, just someone has to do it :slightly_smiling_face:
