How to install the Python SDK

The Python SDK is a pure Python library. The installation should thus be rather straightforward. It supports Python >= 3.6 (older versions may work but are not officially supported). It works on Windows/Mac/Linux.

We recommend to use virtual environment for your development. They make the installation simple and avoid compatibility issues. They also come with their pip command.

⚠️ Make sure that you have the 0.5.4 version of reachy-sdk for your Reachy 2021. Versions subsequent to this one are only compatible with Reachy 2023! ⚠️

From PyPi

pip3 install reachy-sdk==0.5.4

From the source

git clone
pip3 install -e reachy-sdk


The SDK relies on a few third-party Python packages:

  • numpy - mostly for trajectory computation
  • opencv - for camera frame access
  • grpc - to connect to the robot

They will be installed automatically when you install the SDK.
