Parameters:

• root (str or pathlib.Path) – 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 a 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.

__getitem__(index: int) → Tuple[Any, Any]

Parameters:

index (int) – Index

Returns:
