Training the NLU model

Since the release of Rasa 1.0, the training of the NLU models became a lot easier with the new CLI. Train the model by running:

rasa train nlu

Once the model is trained, test the model:

rasa shell nlu

Training the dialogue model

The biggest change in how Rasa Core model works is that custom action 'actions' now needs to run on a separate server. That server has to be configured in a 'endpoints.yml' file. This is how to train and run the dialogue management model:

1. Start the custom action server by running:

rasa run actions

2. Open a new terminal and train the Rasa Core model by running:

rasa train

3. Talk to the chatbot once it's loaded after running:

rasa shell

Starting the interactive training session:

To run your assistant in a interactive learning session, run:

1. Make sure the custom actions server is running:

rasa run actions

2. Start the interactive training session by running:

rasa interactive

Steps to run the complete project

Run the below steps in different terminals

Step 1: Run the Flask server for getting covid data

python app.py

Step 2: Run the Actions Server

rasa run actions

Step 3: Run the Shell to interact with bot

rasa shell

Integration with FrontEnd Website

Step 1: Run the Actions Server

rasa run actions

Step 2: Run the rasa model

python -m rasa run --m ./models --endpoints endpoints.yml --port 5005 --cors "*" -vv --enable-api

Step 3: Run the Flask Server for backend data

python app.py

Step 4: Run the HTTP server for running website for chatbot

The chatbot UI is provided in index.html forked from another repo is also placed for individual learnings into chatbot frontend.

python -m http.server 8008

Here 8008 is port number, u can change if needed

The chatbot is ready at http://localhost:8008

Note: Still the bot needs lot of training data. We can integrate RASA-X for this purpose which is not yet added into this project.
