Examples

Necessary imports.

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

Info

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

batchsize, size, maps = 2, 3, 2
data1 = gpuarray.to_gpu(np.arange(batchsize * size * maps).reshape((batchsize, size, maps)).astype(np.float32))
data2 = gpuarray.to_gpu(np.arange(batchsize * size * maps).reshape((batchsize, size, maps)).astype(np.float16))

print(data1.dtype)
dtype('float32')
print(data2.dtype)
dtype('float16')

cast = Cast(data1.dtype, data2.dtype)
data1 = cast(data1)
print(data1.dtype)
dtype('float16')
