WebJan 10, 2024 · When you need to customize what fit () does, you should override the training step function of the Model class. This is the function that is called by fit () for every batch of data. You will then be able to call fit () as usual -- and it will be running your own learning algorithm. Note that this pattern does not prevent you from building ... WebNow we can set up a simple dummy training batch using __call__(). This returns a BatchEncoding() instance which prepares everything we might need to pass to the model. ... train_dataset = train_dataset. shuffle (100). batch (32). repeat (2) The model can then be compiled and trained as any Keras model: ...
