SAP Data Intelligence ML Scenario with TensorFlow

Currently, we are building our first SAP Data Intelligence ML Scenario with TensorFlow.

However, we do not seem able to find a way to serialise our Keras Modell in the Python Producer graph to pass it to the Artefact Producer operator as a blob so that that the Artefact Consumer operator in the Python Consumer graph can retrieve it respectively to rebuild our model for consumption.

Many thanks for any help or ideas
