Cuda 编译错误:已定义类模板

我是 cuda 的新手，并尝试运行我在网上找到的一个简单的矢量添加示例以开始使用。我正在使用win10 64bit和Visual Studio 2017。

#include "cuda_runtime.h"
#include "cuda.h"
#include "device_launch_parameters.h"
#include <iostream>

#include <math.h>
// Kernel function to add the elements of two arrays
__global__
void add(int n, float *x, float *y)
{
int index = threadIdx.x;
int stride = blockDim.x;
for (int i = index; i < n; i += stride)
y[i] = x[i] + y[i];
}
int main(void)
{
int N = 1 << 20;
float *x, *y;
// Allocate Unified Memory – accessible from CPU or GPU
cudaMallocManaged(&x, N * sizeof(float));
cudaMallocManaged(&y, N * sizeof(float));
// initialize x and y arrays on the host
for (int i = 0; i < N; i++) {
x[i] = 1.0f;
y[i] = 2.0f;
}
// Run kernel on 1M elements on the GPU
add <<<1, 1 >>>(N, x, y);
// Wait for GPU to finish before accessing on host
cudaDeviceSynchronize();
// Check for errors (all values should be 3.0f)
float maxError = 0.0f;
for (int i = 0; i < N; i++)
maxError = fmax(maxError, fabs(y[i] - 3.0f));
std::cout << "Max error: " << maxError << std::endl;
// Free memory
cudaFree(x);
cudaFree(y);
return 0;
}

我使用了"VS2017的开发人员命令提示符"，因为窗口的命令提示符给了我

nvcc fatal : Cannot find compiler 'cl.exe' in PATH

在线解决方案对我不起作用。然后我运行了这个命令(--编译器-选项已经解决了一些错误(

nvcc add.cu --compiler-options "-D _WIN64"

但是编译器仍然给我错误

我一直在寻找解决方案。似乎其他有类似问题的人在他们包含的标头方面遇到了问题，但我的示例代码是从互联网上下载的，上传它的人没有任何问题，这让我对程序的哪个部分有问题感到困惑。

PS：我不知道我的cuda是否正确安装。详： 我无法在我的窗户上安装 cuda，安装一直告诉我安装失败。然后我在帖子 #19 的这个链接中找到了一个解决方案：https://devtalk.nvidia.com/default/topic/1035535/cuda-setup-and-installation/cuda-9-2-does-not-work-with-visual-studio-2017-15-7-1/2 它似乎工作正常，但我不知道这是否是问题所在。
