At a glance:<p><pre><code>  - Only supports fully connected layers for now. No convnets or RNNs.

  - Requires a GPU. No option to run on CPU, not even for development. 

  - Setup instructions for Ubuntu only. No Mac or Windows.

  - Uses JSON to define the network architecture. Which limits what you can build.

  - Takes in data in NetCDF format only.

  - Very little documentation.

  - The name is bad. I&#x27;m not going to remember how to spell DSSTNE.

It seems like a very early proof of concept. I wouldn&#x27;t expect it to be useful to most people at this point. Built-in support for sparse vectors is interesting, but not a strong selling point by itself. I hope Amazon continues to develop it. Or, even better, contribute to one of the existing more mature frameworks.
