mindspore.dataset.vision.ToTensor
- class mindspore.dataset.vision.ToTensor(output_type=np.float32)[source]
Convert the input PIL Image or numpy.ndarray to numpy.ndarray of the desired dtype, rescale the pixel value range from [0, 255] to [0.0, 1.0] and change the shape from (H, W, C) to (C, H, W).
- Parameters
output_type (Union[mindspore.dtype, numpy.dtype], optional) – The desired dtype of the output image. Default:
numpy.float32
.- Raises
TypeError – If the input image is not of type
PIL.Image.Image
ornumpy.ndarray
.TypeError – If dimension of the input image is not 2 or 3.
- Supported Platforms:
CPU
Examples
>>> from mindspore.dataset.transforms import Compose >>> >>> # create a list of transformations to be applied to the "image" column of each data row >>> transforms_list = Compose([vision.Decode(to_pil=True)), ... 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")
