Going Classy

Building classes for model training

So far, the %%writefile magic has helped us to organize the code into three distinct parts: data preparation, model configuration, and model training. At the end of the chapter, Rethinking the Training Loop, though, we bumped into some of its limitations, e.g., being unable to choose a different number of epochs without editing the model training code.

Clearly, this situation is not ideal. We need to do better. We need to go classy; that is, we need to build a class to handle the model training part.

The class

Let us start defining our class with a rather unoriginal name: StepByStep. Since we are starting it from scratch, either we do not specify a parent class or we inherit it from the fundamental object class. I prefer the latter, so our class definition looks like this:
