Run RASA with flask - flask

Question

I want to run RASA with --enable-api inside the python code rather than the command line. Below is my code which is not working. Let me know how can i do that. The issue is once i hit the service because the channel is 'cmdline' it comes to the command line. I don't know how to resolve this.

agent = Agent.load('C:\\xxxx_nlu\\models\\dialogue', interpreter=interpreter, action_endpoint=action_endpoint)
rasa_core.run.serve_application(agent,channel='cmdline')
return agent
if __name__ == '__main__':
app.run("xxx.xx.xx.xxx",5005,debug=True)

Answer 1

You're calling rasa bot in the command line in your run_weather_bot function using below command.
rasa_core.run.serve_application(agent,channel='cmdline')
As you can see its serving as command line application.
I have made some changes in your code for a conversation with rasa chatbot. You can refer AGENT documentation and Weather bot article for connection of RASA agent and how RASA agent handles the input message.
def rasa_agent():
interpreter = RasaNLUInterpreter("Path for NLU")
action_endpoint = EndpointConfig(url="Webhook URL")
agent = Agent.load('Path to Dialogue', interpreter=interpreter, action_endpoint=action_endpoint)
## Next line runs the rasa in commandline
# rasa_core.run.serve_application(agent,channel='cmdline')
return agent
#app.route("/conversations/default/respond",methods=['POST'])
def run_weather_bot(serve_forever=True):
agent = rasa_agent() # calling rasa agent
## Collect Query from POST request
## Send Query to Agent
## Get Response of BOT
output = {} ## Append output
return jsonify(output)
