2、由于安装CUDA 12.8需要Visual Studio 2022 所以要先安装它 安装：Visual Studio 2022 网址：visualstudio.microsoft.com/zh-hans/dow… 安装时勾选 C++桌面开发
3、重启后安装CUDA
developer.nvidia.com/cuda-toolki… CUDA developer.nvidia.com/cuda-downlo…
安装结果： Installed: - Nsight for Visual Studio 2022 - Nsight Monitor Not Installed: - Nsight for Visual Studio 2019 Reason: VS2019 was not found - Integrated Graphics Frame Debugger and Profiler Reason: see developer.nvidia.com/nsight-vsto… - Integrated CUDA Profilers Reason: see developer.nvidia.com/nsight-vsto…
验证工作 C:\Users\username>nvcc -V nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2025 NVIDIA Corporation Built on Fri_Feb_21_20:42:46_Pacific_Standard_Time_2025 Cuda compilation tools, release 12.8, V12.8.93 Build cuda_12.8.r12.8/compiler.35583870_0
4、安装cuDDN 网址：developer.nvidia.com/rdp/cudnn-a… 下载对应的版本
获取你的CUDA路径： C:\Users\username>set cuda CUDA_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.8 CUDA_PATH_V12_8=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.8
解压后复制到以上路径，过程需要授权 验证cuDDN 用管理员身份运行CMD 运行命令.\extras\demo_suite\bandwidthTest.exe 运行命令.\extras\demo_suite\deviceQuery.exe 看到Result = PASS 就大功告成了
