Examples
>>> import numpy >>> from mindspore.dataset.transforms import Compose >>> >>> transforms_list = Compose([vision.Decode(to_pil=True), ... vision.FiveCrop(size=200), ... # 4D stack of 5 images ... lambda *images: numpy.stack([vision.ToTensor()(image) for image in images])]) >>> # apply the transform to dataset through map function >>> image_folder_dataset = image_folder_dataset.map(operations=transforms_list, ... input_columns="image")
