In this competition, our task is to predict what articles each customer will purchase in the 7-day period immediately after the training data ends. I think the phrase the 7-day period immediately after the training data ends is a bit ambiguous.
\nI have two interpretations.
I believe this point is important, because we can ignore many items (e.g., Swimwear) and customers (e.g., a person whose data is missing for years), if interpretation 1 is correct. I am sorry if I missed something.

sample_submission and customers data are having the same number of customers so don't we have to predict for all the customers. Can you please explain this part?
