WebWhat's that about? Here's the issue: When you write a custom Keras layer or Keras loss or Keras model, you are defining code. But when you are exporting the model, you have to make a flat file out of it. What happens to the code? It's lost! How can the prediction work then? You need to tell Keras how to pass in all the constructor arguments etc. WebCustom layers allow you to set up your own transformations and weights for a layer.
