Bot Framework SDK v4 Python

What's new with Bot Framework

This repository contains code for the Python version of the Microsoft Bot Framework SDK, which is part of the Microsoft Bot Framework - a comprehensive framework for building enterprise-grade conversational AI experiences.

This SDK enables developers to model conversation and build sophisticated bot applications using Python. SDKs for JavaScript, .NET and Java (preview) are also available.

To get started building bots using the SDK, see the Azure Bot Service Documentation.

Getting Started

To get started building bots using the SDK, see the Azure Bot Service Documentation.

The Bot Framework Samples includes a rich set of samples repository.

If you want to debug an issue, would like to contribute, or understand how the Bot Builder SDK works, instructions for building and testing the SDK are below.


Python "Virtual Environments" allow Python packages to be installed in an isolated location for a particular application, rather than being installed globally, as such it is common practice to use them. Click here to learn more about creating and activating Virtual Environments in Python.


Clone a copy of the repo:

git clone

Change to the SDK's directory:

cd botbuilder-python

Using the SDK locally

You will need the following 3 packages installed in your environment:

To use a local copy of the SDK you can link to these packages with the pip -e option.

pip install -e ./libraries/botbuilder-schema
pip install -e ./libraries/botframework-connector
pip install -e ./libraries/botbuilder-core
pip install -e ./libraries/botbuilder-integration-aiohttp
pip install -e ./libraries/botbuilder-ai
pip install -e ./libraries/botbuilder-applicationinsights
pip install -e ./libraries/botbuilder-integration-applicationinsights-aiohttp
pip install -e ./libraries/botbuilder-dialogs
pip install -e ./libraries/botbuilder-azure
pip install -e ./libraries/botbuilder-adapters-slack
pip install -e ./libraries/botbuilder-testing

Running unit tests

First execute the following command from the root level of the repo:

pip install -r ./libraries/botframework-connector/tests/requirements.txt
pip install -r ./libraries/botbuilder-core/tests/requirements.txt
pip install -r ./libraries/botbuilder-ai/tests/requirements.txt

Then enter run pytest by simply typing it into your CLI:


This is the expected output:
