Question

我正在我的spyder（python3）上尝试这段代码。

import pycuda.autoinit
import pycuda.driver as drv
import numpy

from pycuda.compiler import SourceModule
mod = SourceModule("""
__global__ void multiply_them(float *dest, float *a, float *b)
{
  const int i = threadIdx.x;
  dest[i] = a[i] * b[i];
}
""")

multiply_them = mod.get_function("multiply_them")

a = numpy.random.randn(400).astype(numpy.float32)
b = numpy.random.randn(400).astype(numpy.float32)

dest = numpy.zeros_like(a)
multiply_them(
        drv.Out(dest), drv.In(a), drv.In(b),
        block=(400,1,1), grid=(1,1))

print (dest-a*b)

但无法运行代码。

ExecError：错误调用'nvcc --version'：[Errno 2]没有这样的文件或目录：'nvcc'：'nvcc'

我的nvcc - 版本是

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation
Built on Tue_Jan_10_13:22:03_CST_2017
Cuda compilation tools, release 8.0, V8.0.61

哪个nvcc /usr/local/cuda-8.0/bin/nvcc
哪个spyder
/家庭/ anaconda3 /斌/ Spyder的
$ conda
/家庭/ anaconda3 / bin中/康达

设备查询：

./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

Detected 1 CUDA Capable device(s)

Device 0: "GeForce 940MX"
  CUDA Driver Version / Runtime Version          9.0 / 8.0

echo $ PATH

我试过在终端上运行代码。然后它运行，但是从sourceModule行本身它显示错误。

此外，我已经尝试过我的Jupiter笔记本和其他Cuda安装的系统。但无法确定问题所在。任何帮助都很明显。
