[AI] Nose tests error with revscoring

Hi, I was trying to setup revscoring[0] on my GNU/Arch Linux. I'm using python3.6 in a virtual environment and installed all dependencies from requirements. However, when I run nosetests in the revscoring directory, it shows the error "AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'"[1] Is the error possibly because I'm using python3.6 or due to something else?
