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。

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,
4 ~) Z, Q0 ^# Zflags.cc{end+1} = '-DENABLE_CUDNN' ;
0 p! l  x; G7 f- Z$ W- k* M9 Tflags.cc{end+1} = ['-I' opts.cudnnIncludeDir] ;
0 s& \6 _/ w' b! j9 H# Tend
4 V) A9 G8 n: z! N" ~4 bThe third line is missing quotes, so change it to:

if opts.enableCudnn,
5 Q- ^1 ?8 D9 g: [; H* C/ kflags.cc{end+1} = '-DENABLE_CUDNN' ;
flags.cc{end+1} = ['-I"' opts.cudnnIncludeDir '"'] ;
end
* |- L& \9 h* j$ \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.
