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 are familiar with Python and already have it installed, you can install nengo by going to your Comand Prompt and running the following commands:
    • pip install nengo
    • pip install nengo_gui

    When this is done, run the Nengo Graphical User Interface by typing nengo_gui

  • If you are not familiar with Python or do not already have it installed, we recommend installing Anaconda, which is a Python distribution that already includes NumPy, the main mathematics library for Python. Once this is installed, run the "Anaconda Command Prompt" and then do
    • pip install nengo
    • pip install nengo_gui
    • nengo_gui
  • 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.
