flask-chatterbot

A web implementation of ChatterBot using Flask.

Local Setup:

1. Ensure that Python, Flask, SQLAlchemy, and ChatterBot are installed (either manually, or run pip install -r requirements.txt).
2. Run app.py with python app.py.
3. The demo will be live at http://localhost:5000/

Note for Python 3.10 Users, you might see the following errors while setup:

1. AttributeError: module 'time' has no attribute 'clock'
2. attributeerror module 'collections' has no attribute 'hashable'. Quick fix is to import Hashable from typing for Python\lib\site-packages\yaml\constructor.py and modifying the collections.hashable to just Hashable, this is not advisable if you don't know the side effects.

How do I deploy this to a web server?

If you do not have a dedicated server, I highly recommend using PythonAnywhere, AWS or Heroku to host your application.

Deploying on Heroku

If you are deploying on Heroku, you will have to change the database adapter from chatterbot.storage.SQLStorageAdapter to chatterbot.storage.MongoDatabaseAdapter since SQLite3 isn't supported. To do this simply change the following line:

english_bot = ChatBot("English Bot", storage_adapter="chatterbot.storage.SQLStorageAdapter")

... to use the MongoDB adapter:

english_bot = ChatBot("English Bot", 
                     storage_adapter = "chatterbot.storage.MongoDatabaseAdapter",
                     database = mongodb_name,
                     database_uri = mongodb_uri)

... where mongodb_name is the name of the database you wish to connect to and mongodb_uri is the URI of a remote instance of MongoDB.
