In your main_knn file,

when I'm running the code below, I get an error. Can you share how to fix it? Thank you.

HG = dgl.heterograph({
('user', 'um', 'movie'): (ratings_train['user_idx'], ratings_train['movie_idx']),
('movie', 'mu', 'user'): (ratings_train['movie_idx'], ratings_train['user_idx'])})

error:
