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' ;
9 D' B0 T: D' l' R* }, \9 vflags.cc{end+1} = ['-I' opts.cudnnIncludeDir] ;
+ ^$ n" Q0 h, M. c: N. O8 ^6 `end
7 A$ h2 U' Z7 D0 n- HThe third line is missing quotes, so change it to:

if opts.enableCudnn,
7 ^* S+ |& V/ s8 ?" zflags.cc{end+1} = '-DENABLE_CUDNN' ;
flags.cc{end+1} = ['-I"' opts.cudnnIncludeDir '"'] ;
9 G/ i! D# ^# w: h  mend
( {; ~/ S3 }0 ~7 _+ ~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.

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。）
