我最近在我的 Ubuntu 12.04 上安装了 ArrayFire 2.1。我想和 Python 一起使用,可以吗?我试过 ArrayFire_Python 但它不完整,它不包括 rotate 等函数。我已经导出了 AF_PATH=/opt/arrayfire

ArrayFire 运行良好:

1 - 我做了(在 examples/helloworld)

make cuda

2 - 运行:
./helloworld_cuda

3 - 获得:

create a 5-by-3 matrix of random floats on the GPU
A [5 3] =
        0.7402     0.4464     0.7762
        0.9210     0.6673     0.2948
        0.0390     0.1099     0.7140
        0.9690     0.4702     0.3585
        0.9251     0.5132     0.6814

element-wise arithmetic
B [5 3] =
        0.7744     0.5317     0.8006
        0.8962     0.7189     0.3905
        0.1390     0.2097     0.7549
        0.9243     0.5531     0.4509
        0.8987     0.5910     0.7299

Fourier transform the result
C [5 3] =
           3.6327 + 0.0000i       2.6043 + 0.0000i       3.1267 + 0.0000i
           0.4689 + 0.4640i       0.3193 + 0.0802i       0.1713 + 0.1441i
          -0.3491 - 0.7454i      -0.2923 - 0.4018i       0.2667 + 0.4886i
          -0.3491 + 0.7454i      -0.2923 + 0.4018i       0.2667 - 0.4886i
           0.4689 - 0.4640i       0.3193 - 0.0802i       0.1713 - 0.1441i

grab last row
c [1 3] =
           0.4689 - 0.4640i       0.3193 - 0.0802i       0.1713 - 0.1441i

zero out every other column
negate the first three elements of middle column
B [5 3] =
        0.0000    -0.5317     0.0000
        0.0000    -0.7189     0.0000
        0.0000    -0.2097     0.0000
        0.0000     0.5531     0.0000
        0.0000     0.5910     0.0000

create 2-by-3 matrix from host data
D [2 3] =
        1.0000     3.0000     5.0000
        2.0000     4.0000     6.0000

copy last column onto first
D [2 3] =
        5.0000     3.0000     5.0000
        6.0000     4.0000     6.0000

最佳答案

arrayfire 的 Python 绑定(bind)现在是 PyPi 的一部分,因此您可以使用 pip install arrayfire 安装它们。
