这个错误

2024-06-27 09:50:04 paddle.vision.datasets.Flowers:1
2024-06-27 09:50:04 <string>:30:22: error: Item "Image" of "Union[Tensor, Image, ndarray[Any, dtype[Any]]]" has no attribute "shape"  [union-attr]
2024-06-27 09:50:04 Found 1 error in 1 file (checked 1 source file)

目前我能想到的解决办法：

• 在示例中的 ... print(type(img), img.shape, label) 加上 # type: ignore
• 用 cast： ... print(type(img), cast(Tensor, img).shape, label)

@SigureMo 帮忙看看？

Suggested change

	def __getitem__(self, idx: int) -> tuple[_ImageDataType, npt.NDArray[Any]]:
	def __getitem__(self, idx: int) -> tuple[_ImageDataType, npt.NDArray[np.int64]]:

在示例中的 ... print(type(img), img.shape, label) 加上 # type: ignore

ignore 吧
