I'm using python3.6 and Django2.0, but the code is supposed to be written in Django1.x. An error occurred when I tried to start the service. This is my first time to contact Django and I hope to get help.
It should be an error in the urls.py file
This is urls.py. This file in the book of .it's GitHub is https://github.com/ai2010/machine_learning_for_the_web/tree/master/chapter_7/server_movierecsys
