ModuleNotFoundError: No module named 'mangaki.algo'

[Ronchy2000]

Hello!
the reproduce of "Non-linear Matrix Factorization with Gaussian Processes" is very helpful for me recently,but there are some problems I
met:

1. where is the dataset named : 'ratings-ordered.csv'
2. how to install mangaki.algo.dataset in my win10.

Thankfully!
