tf.compat.v1.saved_model.predict_signature_def( inputs, outputs ) ### Used in the notebooks | Used in the guide | |---| | - [Migrate the SavedModel workflow](https://www.tensorflow.org/guide/migrate/saved_model) | This function produces signatures intended for use with the TensorFlow Serving Predict API (tensorflow_serving/apis/prediction_service.proto). This API imposes no constraints on the input and output types.
