Is it production ready for serving PyTorch models? How about if I wanted to use something like Go to serve those models? That's fairly straightforward with Keras (Python) trained TF models.
If you are trying to apply one of these libraries to a production system that doesn’t get a lot of throughput you probably shouldn’t be using them (try a linear model first). If you have a high throughput application you probably want tensorflow and just deal with the shittyness.
