Error when running custom action: "ModuleNotFoundError: No module named 'rasa_sdk'"

[Deprecated] Rasa X Community Edition

I have everything installed. I can run the shell perfectly. Now I wanted to start writing some code in custom actions, but the module does not get imported. How do I fix this? I am using visual studio code.

Hello. Before I do that let me tell you something that migh be relevant. I had an old laptop with rasa 2.8 and I had to get rid of it so I uploaded all the rasa files to my drive, and when I got another laptop I installed rasa 3.0 and then replaced the new files with my old ones. Could this be the problem? anyway here is the version: Rasa Version : 3.0.5 Minimum Compatible Version: 3.0.0 Rasa SDK Version : 3.0.4 Rasa X Version : None Python Version : 3.8.10

@mx06148391 Ok, did you create any custom actions, and when you run rasa run actions you see this error. please share your actions.py with me.

from typing import Any, Text, Dict, List
#
from rasa_sdk import Action, Tracker
from rasa_sdk.executor import CollectingDispatcher
#
#
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 []

I didnt write any code yet. I just removed the comments to start using it, but I want the module to import first

Should I try to uninstall everything and start all over using conda?

20

@mx06148391 Yes, I was about to write this and make sure please solve all conflicts.

Do check the rasa --version when you install.

Please try to install anaconda, create a conda environment and install rasa 3.x

Meanwhile, I am seeing this issue
