Thanks @kjdoyle and @yil532. I leave this open for a little while to remind us that we need to help fix the original issue on the pandas community image or move to a recent one if it’s already fixed.

I started having a similar issue trying to bring up anaconda image and the source of the problem is that our kfp bootstrap script needs to update the jupyter client dependency. I will fix that on kfp-notebook.
