Describe the bug(问题描述) get a valueError when running deepfm demo

To Reproduce(复现步骤)

python

# fail and get ValueError: Could not interpret optimizer identifier: <keras.optimizers.optimizer_v2.adam.Adam object at 0x7fbe77391a00>
model.compile(optimizer=tf.keras.optimizers.Adam(learning_rate=learning_rate),
                loss="binary_crossentropy",
                metrics=['accuracy','binary_crossentropy', tf.keras.metrics.AUC(curve='ROC')])

# success
model.compile("adam", "binary_crossentropy",
                metrics=['accuracy','binary_crossentropy',tf.keras.metrics.AUC(curve='ROC')], )
