I use ryu 3.14, error info as below,
hub: uncaught exception: Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/ryu/lib/hub.py", line 52, in

return send_method(data, *args)
error: [Errno 32] Broken pipe
Maybe I should update ryu and try again?

Hi,
Which version of Ryu are you using?
The similar issue was reported before and it should be fixed on the latest.
