I deployed an itemsimilarity recommender and when I call getsimilaritems, it says that this model doesn't support this method. Although in the documentation it says it supports it and when I trained it I could call it (https://dato.com/products/create/docs/generated/graphlab.recommender.itemsimilarityrecommender.ItemSimilarityRecommender.getsimilaritems.html#graphlab.recommender.itemsimilarityrecommender.ItemSimilarityRecommender.getsimilar_items). What is happening?
My data has: userid, itemid columns
I did gl.itemsimilarityrecommender.create to crete an initial model, then I did nn = model1.getsimilaritems() and I used nn to create a new model which I deployed.
What I want is to call getsimilaritems for an item to receive the similar items. The item is a product and I want to get similar products but ones that are most likely to be purchased for the current user. Something like amazon's 'customer who purchased this also purchased' .
