Classification learner Empty: Image Processing

So sorry for my mundane question, but Ima stuck in that. Iam following image processing tutorial and download the code from the link. When I dipplay the classificationLearner from App->CLassification learner, it is empty. There must be some model that I can choose. How can I load the model. I have statistic and machine learning toolbox, so if you haelp me I really appreciate that
