absl-py version

[codon-consulting]

Hi! Just a heads-up that after a fresh installation with micromamba and environment.yml, I was only able to make the regression.py script run after installing absl-py==0.7.0.

With the fresh installation, I got the following trace:

Thanks for notifying us. We can also pin absl-py in our environment files.

I'm surprised that our GitHub actions workflow didn't fail when it last ran two weeks ago. It creates a fresh conda environment and runs regression.py. I'll check what version of absl-py it was using before pinning it.

@codon-consulting I did some testing in #7 and wonder if mamba has something to do with the problem you encountered. When I switched to mamba to install the environment, the installation failed entirely. It worked again with conda, and conda selected absl-py 0.15.0. I've pinned that version in the environment file now so that hopefully others won't run into this problem.

Interesting, the thought crossed my mind but I didn't test it. Thanks for checking and fixing!
