NengoDL 1.0.0 released

The NengoDL team is very excited to announce the release of NengoDL 1.0.0.

What is NengoDL?

NengoDL is a backend for Nengo that integrates deep learning methods (supported by the TensorFlow framework) with other Nengo modelling tools. This allows users to optimize their models using deep learning training methods, improves simulation speed (on CPU or GPU), and makes it easy to insert TensorFlow models (such as a convolutional neural network) 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 model and you run it with

with nengo.Simulator(model) as sim:

you would change that to

with nengo_dl.Simulator(model) as sim:

and that’s it!

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

What’s new?

The 1.0.0 release symbolizes the move from beta to stable release status for NengoDL. This coincides with the release of the NengoDL white paper. And of course we have some new features! Note that this list includes features from the 0.6.2 release, which didn’t get its own announcement (it was intended to be part of 1.0.0, but we wanted to get a release out more quickly to address some package dependency issues users were running in to). So, highlights since the last announcement include: new features that make it easier to extract trained parameters from one model for reuse in another, a number of new configuration options, improved speed for the PES implementation, reduced TensorFlow memory usage for large models, and the option for users to directly specify the output gradient during training (rather than using an objective function). 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
