Installation and Hello World

Installation

To install, run:

git clone https://github.com/rasahq/rasa_core.git
cd rasa_core
pip install -r requirements.txt
pip install -e .

Additional Dependencies

We use Rasa NLU for intent classification & entity extraction, but you are free to use other NLU services like wit.ai, api.ai, or LUIS.ai. In fact, you don’t need to use NLU at all, if your messaging app uses buttons rather than free text.

In addition, you will probably want to use a machine learning library to power one of the policies. Hopefully the requirements for using sklearn_policy.py and keras_policy.py are self-evident.

Hello, World!
