I don't know if you understood my question all i need to do is to load
simple_switch_13.py in my module directly from the Python code...i used
AppManager methods but it doesn't start as i launch from the shell i want to
load the module simple_switch_13 when i check something in my other module that
we can call mymodule what you said i've yet done to bring all dpids...this is
my code to run simple_switch_13.py but i got even assertion error
app_mgr=AppManager.get_instance()
From ryu.app import wsgi
app_mgr.load_apps(['ryu.app.simple_switch_13'])
contexts=app_mgr.create_contexts()
services=[]
services.extend(app_mgr.instantiate_apps(**contexts))
we=wsgi.start_service(app_mgr)
If wsgi:
services.append(hub.spawn(we))
It loads simple_switch_13 and instantiate it correctly but got in assertion
error i think maybe for double OFPHandler instance...so i want to start
simple_switch_13 manually from the Python code this is my goal so can you help
me doing this?
