test_step
- FullyConnected.test_step(data)
- The logic for one evaluation step. - This method can be overridden to support custom evaluation logic. This method is called by Model.make_test_function. - This function should contain the mathematical logic for one step of evaluation. This typically includes the forward pass, loss calculation, and metrics updates. - Configuration details for how this logic is run (e.g. tf.function and tf.distribute.Strategy settings), should be left to Model.make_test_function, which can also be overridden. - Parameters:
- data – A nested structure of `Tensor`s. 
- Returns:
- A dict containing values that will be passed to tf.keras.callbacks.CallbackList.on_train_batch_end. Typically, the values of the Model’s metrics are returned.
