Hi, I am new to ryu. I encountered this problem while starting up ryu controller. I used this command to start it: PYTHONPATH=. ./bin/ryu-manager ryu/app/simple_switch_13.py but it reports an error: ImportError: cannot import name abc Anyone ever met this problem? Please help me. Thanks

I think firstly, you should exterm c0 (mininet> xterm c0) you should run this app in c0 (#ryu-manager ryu.app.simple_switch_13)
