This dataset was built by filtering the images from the YFCC100m dataset that have GPS coordinate corresponding to a ISO-3166 country code. The dataset is balanced by sampling 150 train images, 50 validation images, and 100 test images for each country. Args: root (str or ``pathlib.Path``): Root directory of the dataset. split (string, optional): The dataset split, supports ``"train"`` (default), ``"valid"`` and ``"test"``. transform (callable, optional): A function/transform that takes in a PIL image or torch.Tensor, depends on the given loader, 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 into ``root/country211/``. If dataset is already downloaded, it is not downloaded again. loader (callable, optional): A function to load an image given its path. By default, it uses PIL as its image loader, but users could also pass in ``torchvision.io.decode_image`` for decoding image data into tensors directly. z;https://openaipublic.azureedge.net/clip/data/country211.tgz 84988d7644798601126c29e9877aab6atrainNFrootsplit transformtarget_transformdownloadloaderreturncpt|dd|_t|j}t ||_|dz |_|r|j|js tdt|-t |j |jz |||t ||_y)Nr)rvalidtest country211z;Dataset not found.
