你有没有安装cuda sdk8.0和cudnn，你的计算机有没有和cudnn兼容的NVIDIA的显示卡（需要GTX 650以上档次。）

CUDNN目录不要包含空格。

下面是在stackoverflow上的解答，供题主参考：

Answer by Joss Knight

This appears to be a bug in MatConvNet's vl_compilenn function preventing it from working when your cudnn include path contains spaces. In my version lines 298-301 say:

if opts.enableCudnn,0 K& {4 s" K6 t1 c$ T+ O
flags.cc{end+1} = '-DENABLE_CUDNN' ;
+ }+ o& z% M0 P' z# y9 I# lflags.cc{end+1} = ['-I' opts.cudnnIncludeDir] ;* u0 L2 S- K1 F6 Y$ P' f5 N
end
) G* X; v9 ~9 S% C# s5 MThe third line is missing quotes, so change it to:

if opts.enableCudnn,
5 g( X8 `/ p$ y) O/ Y4 p# ^flags.cc{end+1} = '-DENABLE_CUDNN' ;2 r+ f1 g2 z" l3 x
flags.cc{end+1} = ['-I"' opts.cudnnIncludeDir '"'] ;
S$ H8 J) u5 n7 `end0 {* z" U6 S7 T0 g- d
The actual lines of code may be slightly different in your version of vl_compilenn.

This is a very bad error and I can see similar mistakes being made through that file, which makes me think that somehow under normal circumstances this is not a problem and it's only cropping up on your system for some reason.
