In this post I'll show how to prepare Docker container able to run already trained Neural Network (NN). It can be helpful if you want to redistribute your work to multiple machines or send it to a client, along with one-line run command. Sample code is using Keras with TensorFlow backend. Prerequisites Already prepared Keras NN. We'll save it to...
If you came here, you probably know what is a context processor, but let's quickly recap. It's a function, that returns dictionary of values. Those values will be injected to rendering context without explicitly defining them in view. They allows us to refactor commonly used variables out of views.
