Installation Rasa X

Hi there

First of all, a big thank you to the rasa team. As far you did a great job.

I use rasa for a university project. We “develop” a chat bot for trainees. We started with rasa-nlu, rasa-core and action-server. As soon as you launched rasa 1.0, we also moved to rasa-x as we saw that we can use it for testing and training. Now we wanted to install rasa-x on a ubuntu server. We are struggling with the installation. These are the problems, where we couldn’t find a solution in the docs or in the forum.

  1. After the installation we cannot login via the user interface. “Not all required fields are filled”. We saw that other users had the same problems. A direct login via url /login?username=admin&password=admin12345 works as workaround.
  2. How can we import an existing model from localhost. The curl command doesn’t work.
curl -k -F "model=@20190522-224028.tar.gz" http://86.119.39.164/api/projects/default/models\?api_token\=69e3a8f18abbd42a1c514a2bd704edcef195bdd8
    <h1>Internal Server Error</h1>
    <p>
        The server encountered an internal error and cannot complete
        your request.
    </p>
  1. How can we import existing stories.md and nlu.md?
  2. We also have the problem that the rasa-x bot is not responding. In the logs we retrieve 500.

Can you help me/us to install and configure rasa-x?

Hello @bananenhoschi,

I had the same issues, maybe this can help you :

  1. The username input field is type=“hidden”, you can remove the ‘type’ attribute by editing the HTML to fill the full form. I think, using the URL /login?username=xxxx&password=yyyy is the right thing to do though.
  2. Curl command (when the current directory is the one where is located the model) is working for me. I could send a trained Rasa X model. Maybe a backward compatibility issue ?
  3. For NLU : Go to NLU training page, click on training data page then on the top right corner, click on the arrow facing up. It doesn’t look like there is a way to import stories yet.
  4. Can’t help you for that but I can show you the simple Dockerfile I’m using for testing:

# Base image

FROM python:3.6

# Install Rasa-X

RUN pip3 install rasa-x --extra-index-url Simple Index

# Init Rasa

RUN mkdir -p /app/rasa/projects/

WORKDIR /app/rasa/projects/

RUN rasa init --no-prompt

# Expose port

EXPOSE 5002

Then start it with:

$hostOS> docker run -p 5002:5002 -it rasa-local bash

Then start rasa X:

$container> rasa x

Continuing the discussion from Installation Rasa X:

Oh. Thats sounds nice. Thank you! I will try it and give you feedback. @Rasa is (1.) a known issue?

So far I could import the model (via scp) and import the nlu. As not further documented I think the stories have either to be created manual or maybe via sql-statements.

The only issue I’m struggling with is that bot is not responding.

I followed the quick-installation guide. So I use the stable version of rasa-x.

This is a known issue and will be fixed in the next release. In the meantime can you please modify your credentials.yml to contain the following:

rasa:
  url: ${RASA_X_HOST}/api

and see if that works? You’ll have to restart Rasa X with sudo docker-compose down && sudo docker-compose up -d
