Hi Team,
I'm new to RYU controller and I'm using RYU controller with OVS. I'm
simulating network topology using mininet .
I used the following RYU-MININET link.
http://sourceforge.net/projects/ryu/files/vmimages/OpenFlowTutorial/
While running the following command to active the RYU controller I got the
following errors and I can't ping the host devices that I created.
root@ryu-vm:/home/ryu/ryu# PYTHONPATH=. ./bin/ryu-manager
ryu/app/simple_switch.
py
Traceback (most recent call last):

File "/home/ryu/ryu/ryu/lib/packet/packet_base.py", line 21, in <module>
@six.add_metaclass(abc.ABCMeta)
AttributeError: 'module' object has no attribute 'add_metaclass'
I have no idea what this error means.
Please help me to fix the problem. I really appreciate your help.
Thanks & Regards
Kiran Rokkam
