Traceback (most recent call last):
  File "gameplay.py", line 9, in <module>
    from monopoly_simulator import background_agent_v4
ImportError: cannot import name 'background_agent_v4'

The offending import is here:

GNOME-p3/monopoly_simulator/gameplay.py

Line 9 in fa0862e

from monopoly_simulator import background_agent_v4

Removing the offending important resolves the issue, but perhaps _v4 should be checked into git if it is the correct version.
