Question

我刚开始研究Cuda，尤其是PyCuda。我目前在Windows 7上使用Anaconda。我已经使用Anaconda Prompt安装了Pycuda并尝试了以下代码，我直接从PyCuda文档网页中复制了该代码。但是我有一个CompileError。有没有人有任何建议？

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)

Traceback (most recent call last):

    """)

好的，解决了问题。我只安装了“Microsoft Visual Studio Express”，它似乎不支持编译64位应用程序。但是，我一直在我的电脑上运行64位版本的Anaconda。安装Anaconda 32bit代替修复了这个问题。

在Windows上使用Anaconda的Pycuda CompileError
