Hello,
OpenFlow 1.3+ does not have ports. Hence,
As per* ryu/controller/ofp_handler.py*, we have:
188 # hacky workaround, will be removed. OF1.3 doesn't have
189 # ports. An application should not depend on them. But there
190 # might be such bad applications so keep this workaround for
191 # while.
192 if datapath.ofproto.OFP_VERSION < 0x04:
193 datapath.ports = msg.ports
Now, in *ryu/controller/dpset.py*, we have
163 datapath = msg.datapath
164 datapath.ports = msg.ports
If I* don't have a check* for OF version < 0x04, I get this error:

What can I do to fix this issue? I don't even call ports in my program,
but, I do need dpset module.
Thanks
