Ryu-backend error

[whuwzp]

Hi, I got a problem when I tried to use the "ryu-backend.py", while the "ryu-shim.py" was working regularly. PROBLEM:

• the ryu-shim.py run well, it got:

  loading app ../Engine/ryu-shim/ryu-shim.py
  loading app ryu.controller.ofp_handler
  instantiating app ../Engine/ryu-shim/ryu-shim.py of RyuShim
  Connecting to Core on localhost:5555...
  instantiating app ryu.controller.ofp_handler of OFPHandler

• However, when I run the ryu-backend.py, the program run to completion, and it got :

  loading app ../Engine/ryu-backend/ryu-backend.py
  instantiating app ../Engine/ryu-backend/ryu-backend.py of RyuBackend 

  It seemed the "ryu.controller.ofp_handler" hadn't been loaded and instantiated.

thanks @schwabe @antonis-m @amarsico @farhaven @aleckey

Hi @whuwzp ,

From your logs, I don't clearly see the problem... I think the backend and shim just print different logs and that's all :smiley: Or did you see any other error trace?
