permute¶

tripy.permute(input: Tensor, perm: Sequence[int]) → Tensor[source]¶

Returns a tensor with its dimensions permuted.

Parameters:

input (Tensor) – The input tensor.
perm (Sequence[int]) – The desired ordering of dimensions. It must contain all integers in \([0..N-1]\) exactly once, where \(N\) is the rank of the input tensor.

Returns:

A new tensor.

Return type:

Tensor

Example

Example¶

input = tp.reshape(tp.arange(6, dtype=tp.float32), (2, 3))
output = tp.permute(input, (1, 0))

>>> input
tensor(
    [[0.0000, 1.0000, 2.0000],
     [3.0000, 4.0000, 5.0000]], 
    dtype=float32, loc=gpu:0, shape=(2, 3))
>>> output
tensor(
    [[0.0000, 3.0000],
     [1.0000, 4.0000],
     [2.0000, 5.0000]], 
    dtype=float32, loc=gpu:0, shape=(3, 2))
