Is it possible to install Nengo core or Nengo DL on Jetson TX2 or Xavier?
Yes! Well, I am 99.9% confident that you can, yes, but we have not actually tested it on those two particular board. As far as I’m aware, the Jetson boards have general purpose ARM cores and GPUs, so they can run Python, NumPy, and TensorFlow (unlike other pieces of edge hardware). Those three pieces of software are the only strict requirements for Nengo and NengoDL.
The installation procedure would be to install the Jetson package such that you can use TensorFlow (which depends on NumPy). If you can use TensorFlow on the board, then you will be able to simply
pip install nengo and/or
pip install nengo-dl.
