Nengo 2.0

This is the most recent version of Nengo. It runs on Linux, OS X, and Windows, and the only requirement is that you have Python already installed on your computer.

If you have Python installed, you can install Nengo by running pip install nengo. To install the graphical user interface, run pip install nengo_gui.

  • If you are having difficulty installing Nengo on your computer's version of Python, we recommend installing Anaconda, which is a Python distribution that already includes NumPy, the main mathematics library for Python. Once this is installed, you can do pip install nengo and pip install nengo_gui from within Anaconda.
  • For more installation information, see the documentation here (scroll down).

Nengo is open source. It is available at no charge, but is subject to a license for commercial use. For further details, please view the license file included in the source code, which can be viewed here.
