(tf2.keras) InternalError: Recorded operation 'GradientReversalOperator' returned too few gradients. Saving custom objects with the TensorFlow SavedModel format First, call one of two methods to save the trained model in the TensorFlow SavedModel format. I tried to pass my custom metric with two strategies: by passing a custom function custom_accuracy to the tf.keras.Model.compile method, or by subclassing the MeanMetricWrapper class and giving an instance of my subclass named CustomAccuracy to tf.keras.Model.compile.
