A valid model must be loaded before calling the other methods of the PredictorClient object. This model, typically in the range of 100k to 10M, must be loaded onto the local Web server to ensure a timely response to a prediction request.
The information for the model is loaded from the PredictorModels table. For more information about this table, see Predictor Schema.
The sDWConnStr parameter must be a SQL OLE DB connection string.
Use the LoadModelFromFile method to load a model from a file.
