You will need to install the ``lmdb`` package to use this dataset: run ``pip install lmdb`` 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_outdoor_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.
