TF Serving pipeline

Hallo,
i am using keras-ocr in my project.
to do the detection i need to create a pipeline with 2 models recognizer and detector as folowing:
pipeline = keras_ocr.pipeline.Pipeline(detector=detector, recognizer=recognizer) then use the recognize methode: predictions = pipeline.recognize(images=[image])[0]
how to serve my pipeline using TF serving ?
best regards
