Hi, I am trying to work through the tutorial but I am getting stuck at the very beginning when I try to run the command below. Any input would be much appreciated. Thank you.

from sccoda.util import comp_ana as mod

output:

Hi @jhong26, this looks like an import error with arviz. Could you please check which version of arviz is installed in your environment?

import arviz arviz.__version__

Looks like it was an older version (0.14.0). I no longer get the error after updating the package. Thank you.

pip install arviz --upgrade
