Examples

Necessary imports.

>>> import numpy as np
>>> from PuzzleLib.Backend import gpuarray
>>> from PuzzleLib.Modules import CrossMapLRN

Info

gpuarray is required to properly place the tensor in the GPU.

>>> batchsize, maps, h, w = 1, 10, 2, 2
>>> data = gpuarray.to_gpu(np.random.randn(batchsize, maps, h, w).astype(np.float32))
>>> lrn = CrossMapLRN()
>>> lrn(data)
