计算机上点右键，打开属性->高级系统设置->环境变量，可以看到系统中多了CUDA_PATH和CUDA_PATH_V10_1两个环境变量，接下来，还要在系统中添加以下几个环境变量：
CUDA_SDK_PATH = C:\ProgramData\NVIDIA Corporation\CUDA Samples\v10.1CUDA_LIB_PATH = %CUDA_PATH%\lib\x64CUDA_BIN_PATH = %CUDA_PATH%\binCUDA_SDK_BIN_PATH = %CUDA_SDK_PATH%\bin\win64CUDA_SDK_LIB_PATH = %CUDA_SDK_PATH%\common\lib\x64在系统变量 PATH 的末尾添加：%CUDA_LIB_PATH%;%CUDA_BIN_PATH%;%CUDA_SDK_LIB_PATH%;%CUDA_SDK_BIN_PATH%;再添加如下4条（默认安装路径）：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\lib\x64；C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin；C:\ProgramData\NVIDIA Corporation\CUDA Samples\v10.1\common\lib\x64；C:\ProgramData\NVIDIA Corporation\CUDA Samples\v10.1\bin\win64；
