CelebA — Torchvision 0.22 documentation (original) (raw)

class torchvision.datasets.CelebA(root: Union[str, Path], split: str = 'train', target_type: Union[List[str], str] = 'attr', transform: Optional[Callable] = None, target_transform: Optional[Callable] = None, download: bool = False)[source]¶

Large-scale CelebFaces Attributes (CelebA) Dataset Dataset.

Parameters:

• root (str or pathlib.Path) – Root directory where images are downloaded to.
• split (string) – One of {‘train’, ‘valid’, ‘test’, ‘all’}. Accordingly dataset is selected.
• target_type (string or list, optional) –
  Type of target to use, attr, identity, bbox, or landmarks. Can also be a list to output a tuple with all specified target types. The targets represent:

  • attr (Tensor shape=(40,) dtype=int): binary (0, 1) labels for attributes
  • identity (int): label for each person (data points with the same identity are the same person)
  • bbox (Tensor shape=(4,) dtype=int): bounding box (x, y, width, height)
  • landmarks (Tensor shape=(10,) dtype=int): landmark points (lefteye_x, lefteye_y, righteye_x, righteye_y, nose_x, nose_y, leftmouth_x, leftmouth_y, rightmouth_x, rightmouth_y)
    Defaults to attr. If empty, None will be returned as target.

• transform (callable , optional) – A function/transform that takes in a PIL image and returns a transformed version. E.g, transforms.PILToTensor
• target_transform (callable , optional) – A function/transform that takes in the target and transforms it.
• download (bool, optional) –
  If true, downloads the dataset from the internet and puts it in root directory. If dataset is already downloaded, it is not downloaded again.
  Warning
  To download the dataset gdown is required.
