Texturecache error

Following this post, I downloaded texturecache.py from github (https://github.com/Project-Kodi/texturecache.py) to replace the previous version that throws a warning (thread here). The good news is that this version doesn’t throw a warning. The bad news is that it throws an error:

The old version of texturecache (the one by Milhouse) displays an option list.

What am I missing here?
