The purpose of this repo is to showcase a contextual AI assistant built with the open source Rasa framework.
Sara is an alpha version and lives in our docs, helping developers getting started with our open source tools. It supports the following user goals:
- Understanding the Rasa framework
- Getting started with Rasa
- Answering some FAQs around Rasa
- Directing technical questions to specific documentation
- Subscribing to the Rasa newsletter
- Requesting a call with Rasa's sales team
- Handling basic chitchat
You can find planned enhancements for Sara in the Project Board
To install Sara, please clone the repo and run:
cd rasa-demo
make installThis will install the bot and all of its requirements. Note that this bot should be used with python 3.6 or 3.7.
Use rasa train to train a model (this will take a significant amount of memory to train,
if you want to train it faster, try the training command with
--augmentation 0).
Then, to run, first set up your action server in one terminal window:
rasa run actions --actions actions.actionsThere are some custom actions that require connections to external services,
specifically SubscribeNewsletterForm and SalesForm. For these
to run you would need to have your own MailChimp newsletter and a Google sheet
to connect to. See the development section for instructions on providing
credentials for external services.
In another window, run the bot:
docker run -p 8000:8000 rasa/duckling
rasa shell --debugNote that --debug mode will produce a lot of output meant to help you understand how the bot is working
under the hood. To simply talk to the bot, you can remove this flag.
If you would like to run Sara on your website, follow the instructions here to place the chat widget on your website.
After doing a rasa train, run the command:
rasa test nlu -u test/test_data.json --model models
rasa test core --stories test/test_stories.mddata/core/ - contains stories
data/nlu - contains NLU training data
actions - contains custom action code
domain.yml - the domain file, including bot response templates
config.yml - training configurations for the NLU pipeline and policy ensemble
To install requirements for development, run:
make install-devTo run custom actions locally, put a file called .env in the root of your local directory with values for the following environment variables. Most actions will work without them, but if you are working on actions connecting to external APIs you will need credentials.
GDRIVE_CREDENTIALS=#json access key for Google Drive API for action_submit_sales_form
MAILCHIMP_LIST=#id of mailchimp list for action_submit_subscribe_newsletter_form
MAILCHIMP_API_KEY=#api key for mailchimp
ALGOLIA_APP_ID=#algolia app ID for action_docs_search
ALGOLIA_SEARCH_KEY=#algolia search key
ALGOLIA_DOCS_INDEX=#algolia search index
RASA_X_HOST=#Rasa X domain e.g. localhost:5002
RASA_X_PASSWORD=#password for authenticating into Rasa X
RASA_X_USERNAME=#username for authenticating into Rasa X
RASA_X_HOST_SCHEMA=#Rasa X address schema (http/https)
To run unit tests for custom actions:
make test-actions
To ensure proper database cleanup during testing, you will need to include a connection URL for your tracker store database in your .env file e.g.
TRACKER_DB_URL=postgresql:///tracker
This is not necessary for running the actions.
To ensure a standardized code style we use the formatter black.
If you want to automatically format your code on every commit, you can use pre-commit.
Just install it via pip install pre-commit and execute pre-commit install in the root folder.
This will add a hook to the repository, which reformats files on every commit.
To reformat files manuallly execute
make formatter
