Regression learner - Export model

Hi, I just started working with the "Regression learner" and can make some fits that look promising. I thought that I'd be able to export the regression equation so that I can hard-code it into a different application for general use. I saved the model and tried to export it but when I tried to view the prediction function it was not visible. Is it possible to obtain the model from a fit, particularly for a GPR model? My assumption/thought was that it would be a simple model to code to predict the fit value for new samples (no additional learning, just apply the model).
