- Add scaling by 255 after skimage.transform.resize to convert from [0,1] to [0,255] range - ResNet50 preprocess_input expects [0,255] range, not [0,1] range - Fixes incorrect predictions caused by wrong preprocessing - Applied to both cat image classification and webcam exercise cells - Students still implement preprocess_input and predict steps themselves
