I cannot load data......
1st: PROGRESS: Evaluate model Popularity Model on Purchase Dummy
In this section, the RMSE is all zeros
2nd: PROGRESS: Evaluate model Pearson Similarity on Purchase Dummy
In this section, the RMSE is all ones
3rd: from sklearn.model_selection import train_test_split should replace from sklearn.cross_validation import train_test_split
I might have wrong intuition but it is weird to me that I reran the model twice and still get all zeros and ones in the corresponding section, which is very different from the original notebook in the output. I hope you can clarify for me! Thank you
