Examples

>>> from mindspore.dataset.transforms.py_transforms import Compose, RandomChoice
>>> transforms_list = [py_vision.RandomHorizontalFlip(0.5),
...                    py_vision.Normalize((0.491, 0.482, 0.447), (0.247, 0.243, 0.262)),
...                    py_vision.RandomErasing()]
>>> transforms = Compose([py_vision.Decode(),
...                       py_transforms.RandomChoice(transforms_list),
...                       py_vision.ToTensor()])
>>> image_folder_dataset = image_folder_dataset.map(operations=transforms, input_columns=["image"])
