HybridImageDataset class constructor.

You must replace self.transform with the appropriate transform from

torchvision.transforms that converts a PIL image to a torch Tensor. You

can specify additional transforms $($e$.$g$.$ image resizing$)$ if you want to$,$

but it's not necessary for the images we provide you since each pair has

the same dimensions.

Args:

image$\_$dir: string specifying the directory containing images

cf$\_$file: string specifying the path to the $.$txt file with cutoff

frequency values
