要查看当前系统中安装的CUDA版本,可以通过以下步骤实现:
1. 打开命令行窗口(Windows系统)或终端(Linux/MacOS系统);
2. 运行以下命令:
```
nvcc --version
```
如果系统中安装了CUDA,那么会输出CUDA的版本信息,如:
```
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.168
```
在上述输出中,可以看到CUDA版本为10.1。
此外,如果你想要在代码中查看CUDA版本,可以使用CUDA Runtime API中提供的函数`cudaRuntimeGetVersion`。以下是示例代码:
```c++
#include <cuda_runtime.h>
#include <stdio.h>
int main()
{
int cudaVersion = 0;
cudaError_t cudaStatus = cudaRuntimeGetVersion(&cudaVersion);
if (cudaStatus != cudaSuccess) {
printf("cudaRuntimeGetVersion failed: %s\n", cudaGetErrorString(cudaStatus));
return 1;
}
printf("CUDA version: %d.%d\n", cudaVersion / 1000, (cudaVersion % 100) / 10);
return 0;
}
```
运行上述代码将输出当前系统中安装的CUDA版本号。
