我是 CUDA 和 CUB 的新手。我找到了以下代码并尝试编译它，但是我遇到了这个错误：致命错误：cub/cub.cuh：没有这样的文件或目录。
CUDA 的版本是 7.0.27 我该如何解决这个错误？
谢谢！
#include <cuda.h>
#include <cub/cub.cuh>
#include <stdio.h>
int main(){
// Declare, allocate, and initialize device pointers for input and output
int num_items = 7;
int *d_in;
int h_in[] = {8, 6, 7, 5, 3, 0, 9};
int sz = sizeof(h_in)/sizeof(h_in[0]);
int *d_out; // e.g., [ , , , , , , ]
cudaMalloc(&d_in, sz*sizeof(h_in[0]));
cudaMalloc(&d_out, sz*sizeof(h_in[0]));
cudaMemcpy(d_in, h_in, sz*sizeof(h_in[0]), cudaMemcpyHostToDevice);
printf("\nInput:\n");
for (int i = 0; i < sz; i++) printf("%d ", h_in[i]);
// Determine temporary device storage requirements
void *d_temp_storage = NULL;
size_t temp_storage_bytes = 0;
cub::DeviceScan::InclusiveSum(d_temp_storage, temp_storage_bytes, d_in, d_out, num_items);
// Allocate temporary storage
cudaMalloc(&d_temp_storage, temp_storage_bytes);
// Run inclusive prefix sum
cub::DeviceScan::InclusiveSum(d_temp_storage, temp_storage_bytes, d_in, d_out, num_items);

cudaMemcpy(h_in, d_out, sz*sizeof(h_in[0]), cudaMemcpyDeviceToHost);
printf("\nOutput:\n");
for (int i = 0; i < sz; i++) printf("%d ", h_in[i]);
printf("\n");
return 0;
