After executing the code 2 times I noticed that the RMSE was raising everytime I executed the code.

Yet, if I delete the folder "data" the RMSE returns to:

NDCG@10: 0.0292752140037415
RMSE: 1.108653420946922
P@10: 0.039915164369035125

Second run:

NDCG@10: 0.0292752140037415
RMSE: 3.9881173431634322
P@10: 0.039915164369035125

Third run:

NDCG@10: 0.0292752140037415
RMSE: 7.671051679724568
P@10: 0.039915164369035125

And so on...

Thank you, André

I have been able to replicate the error. I will work on it and let you know once it is fixed. Thanks for the info.
