Error in dataset.py during matrix creation using very large dataset (movielens 1m)
In the "get_length(self, train_name, test_name)" function the return having .nunique() function returns the wrong number of users.
resolved returning:
76) return (data.max(axis = 0)["user"]+1), (data.max(axis = 0)["item"]+1)
and changing 94 to:
94) self.train = sp.dok_matrix((self.num_users , self.num_items ), dtype=np.float32)
