Is that merlin image?

Thanks for the reply. Yes that is the one I mean, I will try my code with merlin-pytorch:23.08 first thing Monday morning.

Thank you for your suggestion @rnyak, but I still receive the same KeyError: 'item_id-list' error. Do you have any other ideas?

I had a mistake in my code, I did not correctly apply the categorify_op:

# Define Groupby Workflow
groupby_feats = userId_op + categ_feats + ...

I added the columns instead of the op. Thanks for your help @rnyak .
