Base class for Preprocessing Layers.

Inherits From: Layer, Module

Don't use this class directly: it's an abstract base class! You may be looking for one of the many built-in preprocessing layers instead.

Preprocessing layers are layers whose state gets computed before model training starts. They do not get updated during training. Most preprocessing layers implement an adapt() method for state computation.

The PreprocessingLayer class is the base class you would subclass to implement your own preprocessing layers.
