We are looking into using mlflow to handle our keras models, and we would also like to use mlflow to deploy the models in e.g azure. But the models require some simple preprocessing of the data, in our case the use of a minmax scaler. For the deployed models to answer correctly they must apply the scaler on the input (and inverse on the output). I have not found any way to include the scaling in the persisted/deployed models. Have I overlooked something, or is it not possible?
