蟒蛇加速 check_cuda()

Question

检查cuda的正确anaconda加速函数是什么？

对于 numba-pro 你可以使用：

>>> from numbapro import check_cuda
numbapro:1: ImportWarning: The numbapro package is deprecated in favour of the accelerate package. Please update your code to use equivalent functions from accelerate.
>>> check_cuda()
CUDA is not available...

或

>>> numbapro.check_cuda()

numbapro 现在给出弃用警告，我无法在 anaconda 加速模块下找到等效的 check_conda() 方法。

Answer 1

我没有看到直接模拟，但底层例程似乎仍然存在，现在在 numba 中：第一部分来自 numba.cuda.cudadrv.libs.test()，它生成对 CUDA 库的搜索。第二个是搜索设备的 numba.cuda.api.detect()。（在适当的加速中，您可以尝试不太详细的 accelerate.cuda.cuda_compatible()，只是 returns true 或 false）例如，

import numba.cuda.api,numba.cuda.cudadrv.libs
numba.cuda.cudadrv.libs.test()
numba.cuda.api.detect()
