I am trying to apply model on two datasetsbut I get an error 'The Input ExampleSet does not match the traing ExampleSet. Grade1 Attribute missing'. I check both the datasets they have this column present. Can you help?
did you maybe set Grade1 to a special role? Rapidminer complains that this attribute isn't there. I would suggest to add a breakpoint before apply model to check this.
