# Revision history [back]

Hi, I had exactly the same issue. I traced it to the file:-

/usr/lib/python2.7/site-packages/networking_arista-2015.1.5.egg-info/entry_points.txt


(The path to this might be different on your system)

It contained the line

arista = neutron.plugins.ml2.drivers.arista.mechanism_arista.AristaDriver


AristaDriver is a class located in the mechanism_arista module, so the last '.' should be a ':' so I changed it to:-

arista = neutron.plugins.ml2.drivers.arista.mechanism_arista:AristaDriver


This allows the module to load successfully, hope this helps.
