Restart a chat conversation


I have written some stories and want to restart the conversation. The problem is after the story flow over, it starts behaving in strange ways. Dialogue management provides wrong bot action towards correctly identified the event.

I am using rasa core .10.04

Here is my sample story. –

## success story without issue
  • greet
    • utter_greet
    • utter_ask_location
  • enter_data{“location”: “banglore”}
    • slot{“location”: “banglore”}
    • utter_thankyou
    • action_search_store

Generated Story -7817183320599229400

  • greet
    • utter_greet
    • utter_ask_location
  • enter_data
    • utter_thankyou
    • action_search_store
    • utter_ask_location
  • enter_data{“location”: “banglore”}
    • slot{“location”: “banglore”}
    • utter_thankyou
    • action_search_store
    • utter_anythingelse
  • deny
    • utter_goodbye

There is a default action provided by Rasa called action_restart. Maybe you want to add that at the end of each story. The action is stated at Actions all the way at the bottom of the page.

I am using rasa core .10.01.

When using it I am getting exception–

with `utter_`. Error: {}".format(action_name, e))
ValueError: Action 'action_restart' doesn't correspond to a template / action. Module doesn't contain a class with this name. Remember to prefix actions that should utter a template with `utter_`. Error: 'action_restart'

Oh, I’m sorry then, I missed out what version of Rasa Core you were on. I’m on v0.11.12 so I’m sorry I don’t think I can help you.

OK It was solved.

using the class

class ActionRestarted(Action):
""" This is for restarting the chat"""

def name(self):
    return "action_chat_restart"

def run(self, dispatcher, tracker, domain):
    return [Restarted()]

and include this action in bot’s domain file.

you should be able to just add - restart to the end

## fallback out of scope
* out_of_scope
  - utter_default
  - action_restart

This is the story I used to restart a conversation, however, it doesn’t run.

fuck you

@akelad What’s the syntax of adding ‘restart’? Do you mean simply adding it to the end of the story? I did this and it seems not working:

* ask_weather{"location": "大和市"}
    - action_ask_weather
    - slot{"time": "午後"}
    - restart 

The history (slot values) from previous utterance is still remembered.

Should be action_restart as far as I know

When I am chatting with my bot after running rasa shell, I type /restart but the bot response strangely. Is there any better way?

Try training using Rasa X - Interactive Learning. While training it will generate a story. Train your bot the correct actions (also check if the intent is correct) it should perform in the interactive learning.
