Error loading plugin discogs

[todd-is-not]

I installed the latest snapshot and plugins and get the following information when I open a terminal or call beets:

** error loading plugin discogs:

Looks like your installation of the discogs_client library is incomplete. Perhaps try reinstalling it; or, if you still get this crash, please report the bug to that project.

pip install -U discogs_client cleared this up for me.
