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  ttj|d||tj|jdt|tr|g}d|D|_ |r| | stdttjtj|jd|_|jdd d d d d  t#t% fd|j|_g|_g|_t-|jD]\}}t/tjtj|jd|}|jt3d|dz|j||gzdS)N caltech101rrTexist_okc0g|]}t|ddS)r)r annotation)r ).0ts n/var/www/tools.fuzzalab.pt/emblema-extractor/venv/lib/python3.11/site-packages/torchvision/datasets/caltech.py z'Caltech101.__init__..4s&nnn]^N1m=WXXnnnHDataset not found or corrupted.
