Args: root (str or ``pathlib.Path``): Root directory of dataset where directory ``caltech101`` exists or will be saved to if download is set to True. target_type (string or list, optional): Type of target to use, ``category`` or ``annotation``. Can also be a list to output a tuple with all specified target types. ``category`` represents the target class, and ``annotation`` is a list of points from a hand-generated outline. Defaults to ``category``. 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. 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. categoryNFroot target_type transformtarget_transformdownloadreturnc s tjtj|d||dtj|jddt|tr|g}dd|D|_ |r,| | s4t dt ttj|jd|_|jd d d d d dttfdd|j|_g|_g|_t|jD]&\}}tttj|jd|}|jtd|d|j||gqgdS)NZ caltech101rrTexist_okcSsg|]}t|ddqS)r)r annotation)r ).0trb/home/www/facesmatcher.com/frenv_anti/lib/python3.10/site-packages/torchvision/datasets/caltech.py 4sz'Caltech101.__init__..HDataset not found or corrupted.
