LFWPairs

class torchvision.datasets.LFWPairs(root: str, split: str = '10fold', image_set: str = 'funneled', transform: Optional[Callable] = None, target_transform: Optional[Callable] = None, download: bool = False)

LFW Dataset.

Parameters

• root (string) – Root directory of dataset where directory lfw-py exists or will be saved to if download is set to True.

• split (string, optional) – The image split to use. Can be one of train, test, 10fold. Defaults to 10fold.

• image_set (str, optional) – Type of image funneling to use, original, funneled or deepfunneled. Defaults to funneled.

• transform (callable, optional) – A function/transform that takes in an PIL image and returns a transformed version. E.g, transforms.RandomRotation
