Rasa integrate with gpt-j

Hi, I want to know that is there any source like website or solution to integrate rasa nlu with gpt-j. I have tried the LanguageModelFeaturizer component in the config file but it does not have the gpt-j model. Also I have tried to add the gpt-j api key in the actions.py file. I’m currently working on the transformer model GPT-J integration with Rasa NLU.

import openai
from typing import Any, Text, Dict, List

   from rasa_sdk import Action, Tracker
   from rasa_sdk.executor import CollectingDispatcher
   def gptj(text):
    api_key = "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"
    response = openai.Completion.create(
    # engine="ada",
    prompt="\n\n" + text,
    stop=[" \n\n"]
    return response ['choices'][0]['text']

# class ActionHelloWorld(Action):

#     def name(self) -> Text:
#         return "action_hello_world"

#     def run(self, dispatcher: CollectingDispatcher,
#             tracker: Tracker,
#             domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
#         dispatcher.utter_message(text="Hello World!")
#         return []
  class ActionDefaultFallback(Action):
       def init(self):
         #  self.gptj = gptj()

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

       async def run(self, dispatcher, tracker, domain):
           query = tracker.latest_message['text']

           return [UserUtteranceReverted()]

The action python file does not work while I run the “rasa run actions” command in the terminal it has a lot of error and an indentation error for the code. When I run “rasa train” and “rasa shell”, it run and works normally without the gpt-j trained on it.

Is there a possible way to connect Rasa NLU with Transformer NLU?
