Caffe: cuDNN not found

[christopher5106]

Hello,
I installed Cuda, and copied cudnn.h to /usr/local/cuda/include/, libcudnn.6.5.dylib libcudnn.dylib libcudnn_static.a to /usr/local/cuda/lib and I get during the cmake command :

-- NVIDIA CUDA:
-- Target GPU(s) : Auto
-- GPU arch(s) : sm_30
-- cuDNN : Not found

on OS X 10.10.4

Do you know why ?

Try running ccmake and setting CUDNN_INCLUDE, CUDNN_LIBRARY and CUDNN_ROOT.

or

cmake  -DCUDNN_INCLUDE="/your/path/to/include" -DCUDNN_LIBRARY="/your/path/to/lib" /path/to/caffe 

if you don't have ccmake.

Great thanks !

[christopher5106]

In CCMAKE i can see also for HDF5_DIR the value HDF5_DIR-NOTFOUND.
Is it a problem ?

[BlGene]

Only if you want to used hdf5.

[christopher5106]

ok thanks

I get the following warnings, will they be problematic ?

your libraries dir might be wrong, I would try getting it to work without CUDNN first and then including it later.

[odellus]

I had the same issue. You have to give the full library path (not just the directory) for cmake to find the library. The flag -DCUDNN_INCLUDE should point to a directory, but if you point it at cudnn.h it should still work. The compiler gripes about it, but it still works.

ok
I created a tutorial (but without cmake) http://christopher5106.github.io/big/data/2015/07/16/deep-learning-install-caffe-cudnn-cuda-for-digits-python-on-mac-osx.html

@christopher5106 I had similar warnings when I tried /usr/lib but it went well after i used /usr/local/cuda/lib which is ../lib from my include directory.
Hope it helps without warnings
