A valid model must be loaded before calling the other methods of the PredictorClient object. A model is originally stored in a database and must be loaded using the LoadModelFromDB method. Once loaded, the model may be saved to a file using the SaveModelToFile method.
The file path is relative to the current working directory of the calling process.
