# torch.rot90

torch.rot90(input, k=1, dims=[0, 1]) → Tensor

  Rotate an n-D tensor by 90 degrees in the plane specified by dims axis. Rotation direction is from the first towards the second axis if k > 0, and from the second towards the first for k < 0.

  Parameters:

    - input (Tensor) – the input tensor.

    - k (int) – number of times to rotate. Default value is 1

    - dims (a list or tuple) – axis to rotate. Default value is [0, 1]

  Example:

      >>> x = torch.arange(4).view(2, 2)
      >>> x
      tensor([[0, 1],
              [2, 3]])
      >>> torch.rot90(x, 1, [0, 1])
      tensor([[1, 3],
              [0, 2]])

      >>> x = torch.arange(8).view(2, 2, 2)
      >>> x
      tensor([[[0, 1],
               [2, 3]],

              [[4, 5],
               [6, 7]]])
      >>> torch.rot90(x, 1, [1, 2])
      tensor([[[1, 3],
               [0, 2]],

              [[5, 7],
               [4, 6]]])
