Replicate¶
Description¶
This module replicates the output of the previous layer and is used to branch the neural network when it is built using Sequential.
Initializing¶
def __init__(self, times, name=None):
Parameters
| Parameter | Allowed types | Description | Default |
|---|---|---|---|

Examples¶
Necessary imports.
>>> import numpy as np
>>> from PuzzleLib.Backend import gpuarray
>>> from PuzzleLib.Modules import Replicate
Info
gpuarray is required to properly place the tensor in the GPU
>>> np.random.seed(1234)
>>> batchsize, maps, h, w = 1, 1, 5, 5
>>> data = gpuarray.to_gpu(np.random.randint(0, 9, (batchsize, maps, h, w)).astype(np.float32))
>>> print(data)
