I am just climbing the learning curve on using pymc for model comparison. I’m seeing a strange error that I didn’t see mentioned elsewhere in this forum or gh issues (apologies if I missed it). I’m getting the same error that is currently popping up on the docs page. https://www.pymc.io/projects/…

[image] OriolAbril: pip install -U --pre arviz Yes! That did seem to fix it. Just for reference, everything seems to be working in arviz>=0.13.0rc1 Thanks so much.

Possible bug using arviz.compare on pymc models

Can you try pip install -U --pre arviz to see if it fixes the issue?
