    :: DeveloperApi :: Engine developers should not use this directly.

    :: DeveloperApi :: Engine developers should not use this directly. Prepare a model for persistence in the downstream consumer. PredictionIO supports 3 types of model persistence: automatic persistence, manual persistence, and re-training on deployment. This method provides a way for downstream modules to determine which mode the model should be persisted.

    sc

    Spark context

    modelId

    Model ID

    algoParams

    Algorithm parameters that trained this model

    bm

    Model

    returns

    The model itself for automatic persistence, an instance of org.apache.predictionio.workflow.PersistentModelManifest for manual persistence, or Unit for re-training on deployment
