NengoDL 3.4.0 released

The NengoDL team is happy to announce the release of NengoDL 3.4.0.

What is NengoDL?

NengoDL is a backend for Nengo that integrates deep learning methods (supported by the TensorFlow framework) with other Nengo modelling tools. NengoDL allows users to optimize their models using deep learning training methods, improves simulation speed (on CPU or GPU), can automatically convert Keras models to Nengo networks, and makes it easy to insert TensorFlow code (individual functions or whole network architectures) into Nengo networks.

How do I use it?

To use NengoDL, replace instances of nengo.Simulator with nengo_dl.Simulator.

For example, if you have a network called net and you run it as

with nengo.Simulator(net) as sim:
    sim.run(10)

you would change that to

with nengo_dl.Simulator(net) as sim:
    sim.run(10)

and that’s it!

Information on accessing the more advanced features of NengoDL can be found in the documentation.

What’s new?

3.4.0 is largely a compatibility release. It adds compatiblity with TensorFlow 2.4.0, Nengo 3.1.0, and adds support for KerasSpiking in the NengoDL Converter. And as always, we fixed some bugs! Check out the GitHub release page for a full changelog.

How do I get it?

To install NengoDL, we recommend using pip:

pip install nengo-dl
