[`tf.compat.v1.saved_model.signature_def_utils.regression_signature_def`](https://www.tensorflow.org/api_docs/python/tf/compat/v1/saved_model/regression_signature_def)

<br />

    tf.compat.v1.saved_model.regression_signature_def(
        examples, predictions
    )

This function produces signatures intended for use with the TensorFlow Serving
Regress API (tensorflow_serving/apis/prediction_service.proto), and so
constrains the input and output types to those allowed by TensorFlow Serving.
