Examples

Necessary imports.

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

Info

gpuarray необходим для правильного размещения тензора на GPU

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