RandAugment

class torchvision.transforms.RandAugment(num_ops: int = 2, magnitude: int = 9, num_magnitude_bins: int = 31, interpolation: InterpolationMode = InterpolationMode.NEAREST, fill: Optional[List[float]] = None)[source]

RandAugment data augmentation method based on “RandAugment: Practical automated data augmentation with a reduced search space”. If the image is torch Tensor, it should be of type torch.uint8, and it is expected to have […, 1 or 3, H, W] shape, where … means an arbitrary number of leading dimensions. If img is PIL Image, it is expected to be in mode “L” or “RGB”.

Parameters:
  • num_ops (int) – Number of augmentation transformations to apply sequentially.

  • magnitude (int) – Magnitude for all the transformations.

  • num_magnitude_bins (int) – The number of different magnitude values.

  • interpolation (InterpolationMode) – Desired interpolation enum defined by torchvision.transforms.InterpolationMode. Default is InterpolationMode.NEAREST. If input is Tensor, only InterpolationMode.NEAREST, InterpolationMode.BILINEAR are supported.

  • fill (sequence or number, optional) – Pixel fill value for the area outside the transformed image. If given a number, the value is used for all bands respectively.

Examples using RandAugment:

forward(img: Tensor) Tensor[source]

img (PIL Image or Tensor): Image to be transformed.

Returns:

Transformed image.

Return type:

PIL Image or Tensor
