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,
flags.cc{end+1} = '-DENABLE_CUDNN' ;
flags.cc{end+1} = ['-I' opts.cudnnIncludeDir] ;
end
3 c3 t0 d2 ]2 P/ M6 kThe third line is missing quotes, so change it to:

if opts.enableCudnn,
flags.cc{end+1} = '-DENABLE_CUDNN' ;
9 J% [/ @% C: f; `8 c" H% u5 I! G( mflags.cc{end+1} = ['-I"' opts.cudnnIncludeDir '"'] ;

* X6 [, ~' F) N" @+ LThe 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.
