CUDNN目录不要包含空格。

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,
, e  f% e5 a- t' x$ J2 Y. H6 uflags.cc{end+1} = '-DENABLE_CUDNN' ;
3 p, N# S0 H4 v; s! ^' Tflags.cc{end+1} = ['-I' opts.cudnnIncludeDir] ;
4 @, x$ \( u3 f$ I3 Yend
& R9 [  H4 R# u' [' LThe third line is missing quotes, so change it to:

if opts.enableCudnn,4 V; t' ~) T9 Z9 I  C1 N+ z6 Q
flags.cc{end+1} = '-DENABLE_CUDNN' ;
1 G/ j% S0 I8 pflags.cc{end+1} = ['-I"' opts.cudnnIncludeDir '"'] ;
# a1 U2 G0 B# ]$ ?: A2 Kend* ^' d# o6 v2 Y6 B  I- Z1 w1 c# T& H/ b1 o
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.
