 #### Set up SPyNet
 Set up SPyNet according to the image size and model. For optimal performance, resize your image such that width and height are a multiple of 32. You can also specify your favorite model. The present supported modes are fine tuned models `sintelFinal`(default) and `sintelClean`, and base models `chairsFinal` and `chairsClean`.
