Result = PASS

比如我这个显卡 CUDA Capability Major/Minor version number: 7.5 是 7.5 ，而我把 CUDA C/C++/Device/Code Generation 设置的 compute_80,sm_80 ，自然不匹配了，所以报错，设置 compute_75,sm_75 即可。

如果要查看设置的更多帮助信息 使用 nvcc --help

If you are using Visual Studio:

Right click on the project > Properies > Cuda C/C++ > Device

and add the following to Code Generation field

bcdedit /set testsigning on
bcdedit /set testsigning off
