'cudnn.h' file not found error [OS X]

[luzhi]

When I try to compile caffe by make all, I got the following error message:

In file included from src/caffe/blob.cpp:1:
In file included from ./include/caffe/blob.hpp:4:
In file included from ./include/caffe/common.hpp:18:
In file included from ./include/caffe/util/device_alternate.hpp:40:
./include/caffe/util/cudnn.hpp:5:10: fatal error: 'cudnn.h' file not found

include <cudnn.h>

          ^

make: *** [.build_release/src/caffe/blob.o] Error 1

My platform is OS X 10.9 with GPU (so, I uncommented the line "USE_CUDNN" and downloaded the cuDNN.

I did not find any file called "cudnn.h" in the cuDNN package downloaded from Nvidia website.

Could you please advise me any solution to this problem? Thanks!

You need register as the CUDA developer first and then you will get the dowload link.

Are you sure cudnn lib is available for OS X? Last time I checked, there was not support for OS X.

Hi, @zhfe99 , yes, I downloaded the cuDNN from the link.

Hi, @vimalthilak , the latest version provides a link for OS X platform. But in the package, there is no file called cudnn.h. Instead, there is a shortcut file called libcudnn.dylib. Also, it contains the other files: libcudnn.6.5.dylib, libcudnn_static.a. Please see the screenshot of the folder following:

Thanks for both you guys!

@luzhi Thanks for pointing out that cuDNN v2 RC now supports OS X! It looks like there is a bug in the release package in that there is not header file! You could file a bug at developer.nvidia.com asking for an updated release package. If you are feeling adventurous, you could try using the include file in the linux package.

I ran into this as well. I did file a bug with nvidia. In the meantime I also tried using the header file from the linux version but that blows up on compile with seemingly mismatched parameters.

@bgreen-litl @luzhi
Received an email from nvidia that the package has been updated.

Please note that caffe doesn't use cud R2 yet. I was advised to wait for a few weeks before checking whether cudnn R2 has been enabled. Until then, I suppose you could play around with cudnn directly.

[bgreen-litl]

Ah, okay. Thanks. The nvidia folks said that the header file from the linux tarball should work, but it didn't for me so perhaps that's why.

#1740 updates the Caffe Makefile for Yosemite and #1731 will integrate cuDNN R2 (see #1739 for an initial complete patch). Try installing on OS X with cuDNN R2 with both of these PRs merged -- or wait for the next release to master.
