Hi, We are trying to manage openVswitch using ryu controller using OVSDB manager. But we are facing an Attribute error while doing the same.
File "/root/venv/lib/python3.4/site-packages/ovs/db/idl.py", line 266, in
send_cond_change
if table.cond_changed:
AttributeError: 'TableSchema' object has no attribute 'cond_changed'
Ryu application and the logs are attached.
Please help us in understanding why the error is coming, though the schema is
received from the openVswitch.
Thanks and Regards,
Srujana.
