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:

Hi I'm reproducing your model what is very useful things at my field.

and then happen 2 errors here , I can't even take results for evaluation stage.

I wonder how resolve these errors that is occurs at movie-lens.py

1. nlp = stanford isn't work now to me , stanford ->stanza ( change the library then work well )

2. at last session , build the interacted_movies data

the error message as follows gotten to me

[pandas couldn't support one function espeically, Passing list-likes to .loc or [] with any missing labels is no longer supported. The following labels were missing: Int64Index([550972], dtype='int64'). See https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#deprecate-loc-reindex-listlike"]

thank you !
