import openai

from typing import Any, Text, Dict, List

from rasa_sdk import Action, Tracker
from rasa_sdk.events import SlotSet
from rasa_sdk.types import DomainDict
from rasa_sdk.executor import CollectingDispatcher

from rasa_sdk.events import (
    SlotSet,
    UserUtteranceReverted,
    ConversationPaused,
    EventType,
)

class ActionOpenaiChat(Action):

    def name(self) -> Text:
        return "action_openai_chat"

    def run(
        self, 
        dispatcher: CollectingDispatcher,
        tracker: Tracker,
        domain: DomainDict) -> List[EventType]:

        openai.api_key = "insert api key from openAI"
        response = openai.Completion.create(
            model="text-davinci-002",
            prompt="The following is a conversation with an AI assistant. The assistant is helpful, creative, clever and very friendly.\n\nHuman: Hello, who are you?\nAI: I am an AI created by OpenAI. How can I help you today?\nHuman: {}\nAI:".format(tracker.latest_message['text']),
            temperature=0.9,
            max_tokens=150,
            top_p=1,
            frequency_penalty=0.0,
            presence_penalty=0.6,
            stop=[" Human:", " AI:"]
        )
        
        if 'choices' in response.keys():
            if len(response['choices']) > 0:
                dispatcher.utter_message(text="{}".format(response['choices'][0]['text']))
            else:
                dispatcher.utter_message(text="Unfortunately, the internet doesn't have an answer to your question either.")
        else:
            dispatcher.utter_message(text="Unfortunately, the internet doesn't have an answer to your question either.")
        
        return []
