ValueError: Test interactions matrix and train interactions matrix share 95786 interactions. This will cause incorrect evaluation, check your data split.
Hi
I am trying to create a hybrid recommender using item's features
I have a dataset with 478,930 interactions
I am quite sure that each user-item pairs available only once in my data,
so it should be no interactions shared between train and test sets
However, I keep getting the issue:
ValueError: Test interactions matrix and train interactions matrix share 95786 interactions. This will cause incorrect evaluation, check your data split.
How can I solve this? What are the potential reasons for this?
I am having the same problem.
