ImageFolder
(root: str, transform: Optional[Callable] = None, target_transform: Optional[Callable] = None, loader: Callable[[str], Any] = <function default_loader>, is_valid_file: Optional[Callable[[str], bool]] = None)[source]¶ A generic data loader where the images are arranged in this way by default:
root/dog/xxx.png root/dog/xxy.png root/dog/[...]/xxz.png root/cat/123.png root/cat/nsdf3.png root/cat/[...]/asd932_.png
This class inherits from
DatasetFolder
so the same methods can be overridden to customize the dataset.- Parameters
root (string) – Root directory path.
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.
loader (callable, optional) – A function to load an image given its path.
is_valid_file – A function that takes path of an Image file and check if the file is a valid file (used to check of corrupt files)
