样例:
>>> import mindspore.dataset as ds >>> import mindspore.dataset.vision as vision >>> from mindspore.dataset.transforms import Compose >>> >>> # data is already decoded, but not in PIL Image format >>> transforms_list = Compose([vision.ToPIL(), ... vision.RandomHorizontalFlip(0.5), ... vision.ToTensor()]) >>> # apply the transform to dataset through map function >>> image_folder_dataset = ds.ImageFolderDataset("/path/to/image_folder_dataset_directory") >>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list, ... input_columns="image")
