class_docstr: `LSUN <http://lsun.cs.princeton.edu>`_ dataset.
  
  Args:
      root (string): Root directory for the database files.
      classes (string or list): One of {'train', 'val', 'test'} or a list of
          categories to load. e.g. ['bedroom_train', 'church_train'].
      transform (callable, optional): A function/transform that  takes in an PIL image
          and returns a transformed version. E.g, ``transforms.RandomCrop``
      target_transform (callable, optional): A function/transform that takes in the
          target and transforms it.
