mindspore.ops.Transpose

class mindspore.ops.Transpose[source]

Permutes the dimensions of the input tensor according to input permutation.

Inputs:

  • input_x (Tensor) - The shape of tensor is \((x_1, x_2, ..., x_R)\).

  • input_perm (tuple[int]) - The permutation to be converted. The elements in input_perm are composed of the indexes of each dimension of input_x. The length of input_perm and the shape of input_x must be the same. Only constant value is allowed. Must be in the range [0, rank(input_x)).

Outputs:

Tensor, the type of output tensor is the same as input_x and the shape of output tensor is decided by the shape of input_x and the value of input_perm.

Raises

  • TypeError – If input_perm is not a tuple.

  • ValueError – If length of shape of input_x is not equal to length of shape of input_perm.

  • ValueError – If the same element exists in input_perm.

Supported Platforms:

Ascend GPU CPU

Examples

>>> input_x = Tensor(np.array([[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]), mindspore.float32)
>>> input_perm = (0, 2, 1)
>>> transpose = ops.Transpose()
>>> output = transpose(input_x, input_perm)
>>> print(output)
