Transpose Operator.
The input tensor will be permuted according to the ax

es given.
The
op functions is similar to how numpy.transpose works in python
.
The input tensor will be permuted according to the axes given.
The
behavior of this operator is similar to how `numpy.transpose` works
.
For example:
- suppose the input `X` is a 2-D tensor:
$$
X = \begin{pmatrix}
0 &1 &2 \\
3 &4 &5
\end{pmatrix}$$
.. code-block:: text
the given `axes` is: $[1, 0]$, and $Y$ = transpose($X$, axis)
input = numpy.arange(6).reshape((2,3))
then the output $Y$ is:
the input is:
$$
Y = \begin{pmatrix}
0 &3 \\
1 &4 \\
2 &5
\end{pmatrix}$$
array([[0, 1, 2],
[3, 4, 5]])
given axis is:
[1, 0]
output = input.transpose(axis)
then the output is:
array([[0, 3],
[1, 4],
[2, 5]])
So, given a input tensor of shape(N, C, H, W) and the axis is {0, 2, 3, 1},
the output tensor shape will be (N, H, W, C)
- Given a input tensor with shape $(N, C, H, W)$ and the `axes` is
$[0, 2, 3, 1]$, then shape of the output tensor will be: $(N, H, W, C)$.
