Hello there! Install is completed, postgresql set up, db population done, server is up, I chose some movies and bought some of them. But as long as I click on my user profile link in app I see in command window 2 erros (here is full log from the point of clicking):

1) How to cope with this path ? (./models/bpr/item_bias.data) <-- path exists in code "bpr_recommender.py" It does not exist and no such file - item_bias.data. 2) Obvously its impossible to create such directory name (../2018-01-01 10:01:34.179393/..) in windows. But such code exists in this project ("funksvd_recommender.py"). Is this error ?

I run: Python 3.7.3. 64bit, win 10

Appreciate your advices.
