Check environment settings of CUDA, normally all the settings of CUDA had been added to Windows environment
Copy files inbin,libandincludeof cuDNN tobin,libandincludeof CUDA respectively. Normally the directory isC:\Program
Files\NVIDIA GPU Computing Toolkit\CUDA
注意二：在安装了CUDA Drivers后，还必须下载cuDNN，解压后将cudnn64_5.dll拷贝到能通过环境变量path找到的路径下。为避免混乱，我是拷贝到了NVIDIA GPUComputing Toolkit\CUDA\v8.0\bin目录下。否则你将会遇到上面这个问题：
注意cudnn64_7.dll是不行的，不知道为啥
