mindspore.dataset.vision.ToPIL

class mindspore.dataset.vision.ToPIL[源代码]

将已解码的numpy.ndarray图像转换为PIL图像。

Note

转换模式将根据 PIL.Image.fromarray 由图像的数据类型决定。

异常:

  • TypeError - 当输入图像的类型不为 numpy.ndarrayPIL.Image.Image

支持平台:

CPU

样例:

>>> 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 = image_folder_dataset.map(operations=transforms_list,
...                                                 input_columns="image")
