Rasa socket.io vs Rasa 2.6 + Action server

Rasa Open Source
1

I’m stuck!

I made chatbot with Rasa 2.6 and action server 2.6. It works in shell mode and then I moved to test with webchat client. Rasa failed to socket.io error, which have been issue since version 2.2. So I downgraded Action server to 2.2 but then Action server failed with error

ModuleNotFoundError: No module named ‘typing_extensions’

So I’m stuck between version 2.6 and 2.2

Rasa Open Source #actionserver #socketio #rasaopensource

Thanks, but no success, here are my files, first is Dockerfile

# Extend the official Rasa SDK image
FROM rasa/rasa-sdk:2.2.0
#COPY * /app/

# Use subdirectory as working directory
WORKDIR /app

# Copy any additional custom requirements, if necessary (uncomment next line)
# COPY actions/requirements-actions.txt ./

# Change back to root user to install dependencies
USER root

# Install extra requirements for actions code, if necessary (uncomment next line)
# RUN pip install -r requirements-actions.txt
# RUN pip install typing_extensions


# Copy actions folder to working directory
COPY ./actions /app/actions
RUN python -m pip install --upgrade pip
RUN pip install typing_extensions

# By best practices, don't run the code with root user
USER 1003

Build command

docker build . -t rasa-sdk:2.2.0

and result is OK

So Successfully installed typing-extensions-3.10.0.0

Then container creation command

docker run -v $(pwd)/actions:/app/actions --net action-link --name action-server-prod rasa/rasa-sdk:2.2.0

And fail

What to try next?

@InnoOmnia Check both the container rasa2.6 and rasa action server container’s, that they have the typing_extensions or not and even check the action.py that you have import the typing?

Try executing the code without docker files or docker-compose on the local machine.

I got it working, fault and solution

First Docker file, small changes, but no solution

# Extend the official Rasa SDK image
FROM rasa/rasa-sdk:2.2.0
#COPY * /app/

# Use subdirectory as working directory
WORKDIR /app

# Copy any additional custom requirements, if necessary (uncomment next line)


# Change back to root user to install dependencies
USER root

# Install extra requirements for actions code, if necessary (uncomment next line)


# Copy actions folder to working directory
COPY ./actions /app/actions

# Install extra requirements for actions code, if necessary (uncomment next line)
RUN python -m pip install --upgrade pip
RUN pip install --no-cache-dir typing_extensions

# By best practices, don't run the code with root user
USER 1003

after that this command

docker build . -t rasa-sdk:2.2.1

It created these two images

[paulii@vetbot-v4 /pilleribot TUOTANTO]$ docker images
REPOSITORY      TAG          IMAGE ID       CREATED          SIZE
rasa-sdk        2.2.1        99378085f6d5   57 minutes ago   165MB
rasa/rasa-sdk   2.2.0        a1c9443b5df6   6 months ago     151MB

and then this command

docker run -v $(pwd)/actions:/app/actions --net action-link --name action-server-prod rasa/rasa-sdk:2.2.0

and that was the fault. Docker build two images, original (rasa/rasa-sdk 2.2.0) and modified one (rasa-sdk 2.2.1). In the command I run, I used rasa/rasa-sdk:2.2.0, which pointed to original sdk image, which, of course don’t have typing_extensions installed.

SOLUTION
Run command

docker run -v $(pwd)/actions:/app/actions --net action-link --name action-server-prod rasa-sdk:2.2.1

which points to modified (and right) docker image (rasa-sdk:2.2.1 )
