SwapAxes¶

Description¶

Info

Parent class: Module

Derived classes: -

This module reverses the tensor values along the axes. An analog of the swapaxes function in numpy.

def __init__(self, axis1, axis2, name=None):

Parameters

Parameter	Allowed types	Description	Default
axis1	int	First axis index	-
axis2	int	Second axis index	-
name	str	Layer name	None

Necessary imports.

import numpy as np
from PuzzleLib.Backend import gpuarray
from PuzzleLib.Modules import SwapAxes

Let us form the data tensor. Please, pay attention to the current format: (batchsize, insize).

shape = (10, 3, 5, 4, 2)
data = gpuarray.to_gpu(np.random.randn(*shape).astype(np.float32))
print(data.shape)

(10, 3, 5, 4, 2)

swap = SwapAxes(axis1=2, axis2=4)
outdata = swap(data)
print(outdata.shape)

(10, 3, 2, 4, 5)

swap = SwapAxes(axis1=0, axis2=2)
outdata = swap(data)
print(outdata.shape)

(5, 3, 10, 4, 2)
