Installing

If you are familiar with virtualenv create a new one after cloning the repo.

I am naming my env venv:

Python2:

virtualenv -p /usr/local/bin/python venv

Python3:

virtualenv -p /usr/local/bin/python3 venv

If you are using bash activate your env:

. venv/bin/activate

Fish users just use the fish version.

. venv/bin/activate.fish

After activating you get a similar prompt:

(venv) ~/c/s/ice-cream-truck (master ⚡☡=)

Installing libraries:

pip install -r requirements.txt

Startung up the bot:

(venv) ~/c/s/ice-cream-truck (master ⚡→☡=) python chatbot.py
Using TensorFlow backend.
