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 (string): 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 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. 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. z;https://openaipublic.azureedge.net/clip/data/country211.tgzZ 84988d7644798601126c29e9877aab6atrainNF)rootsplit transformtarget_transformdownloadreturncsvt|dd|_t|}t||_|d|_|r:||sJt dt j t|j|j||dt||_dS)Nr )r ZvalidtestZ country211z;Dataset not found.
