[docs]class CUB200(ImageList): """`Caltech-UCSD Birds-200-2011 <http://www.vision.caltech.edu/visipedia/CUB-200-2011.html>`_ \ is a dataset for fine-grained visual recognition with 11,788 images in 200 bird species. \ It is an extended version of the CUB-200 dataset, roughly doubling the number of images. Args: root (str): Root directory of dataset split (str, optional): The dataset split, supports ``train``, or ``test``. sample_rate (int): The sampling rates to sample random ``training`` images for each category. Choices include 100, 50, 30, 15. Default: 100. 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. transform (callable, optional): A function/transform that takes in an PIL image and returns a \ transformed version. E.g, :class:`torchvision.transforms.RandomCrop`. target_transform (callable, optional): A function/transform that takes in the target and transforms it. .. note:: In `root`, there will exist following files after downloading. :: train/ test/ image_list/ train_100.txt train_50.txt train_30.txt train_15.txt test.txt """ download_list = [ ("image_list", "image_list.zip",
