Custom Callback Example — Tensorflow Code
Define a custom callback to print loss after each epoch.
import tensorflow as tf
class PrintLossCallback(tf.keras.callbacks.Callback):
def on_epoch_end(self, epoch, logs=None):
print(f"Epoch {epoch+1}: loss = {logs['loss']}")
model = tf.keras.Sequential([tf.keras.layers.Dense(1, input_shape=[1])])
model.compile(optimizer='sgd', loss='mse')
model.fit([1,2,3], [2,4,6], epochs=5, callbacks=[PrintLossCallback()])Tensorflow Language Guide
