Some thing wrong with the evaluation process or the sampling method?

Hey I actually implemented the model by myself and running it using the metrics provided in your repo. The performance is not good and NDCG3 always higher than the NDCG10 with 10 or 20 percent. I thought that there may be some mistakes with my model. Then I simply run the code provided in your repo to check your model's result. However, the result is the same as my own. I think it seems like no error in the model implementation. So I am wondering that maybe there are some mistakes in the evaluation process or the sampling methods?
