Can't get Theano to communicate with CUDNN on OSX
After a big battle, I was finally able to get Theano to use the GPU on OSX. But now I've tried everything I remember and Theano still can't use CuDNN.
I have installed CUDA version 7 and CUDNN version 3.
I tried to copy the libraries to /usr/local/cuda/lib
as well as to /usr/local/cuda/lib64
, the include file was copied to/usr/local/cuda/include
My. theanorc
[global]
floatX = float32
device = gpu
force_device = True
allow_gc = False
optimizer_including=cudnn
# warn_float64 = warn
# openmp = True
[nvcc]
fastmath = True
flags = -L/Users/morgado/anaconda/lib/
[cuda]
root = /usr/local/cuda
[gcc]
cxxflags = -L/usr/local/cuda/lib64
And my .profile has the relevant parts:
# CUDA
CUDA_ROOT=/usr/local/cuda
export PATH=$CUDA_ROOT/bin:$PATH
export DYLD_LIBRARY_PATH=$CUDA_ROOT/lib:$DYLD_LIBRARY_PATH
export LD_LIBRARY_PATH=$CUDA_ROOT/lib:$CUDA_ROOT/lib64:$LD_LIBRARY_PATH
But still, when I try to get Theano to use CUDNN, I get (with files in lib64) an error:

It seems that clang is not getting the cudnn library even when I specifically told it to check this path.
