I am trying to enable GPU acceleration on my Mac OSX:
I have install CUDA toolkit
I have downloaded cuDNN and place the include and libs in the
/usr/local/cuda/lib and include folders
I have update my .bash_profile as follows:
export CUDA_ROOT=/usr/local/cuda
export LD_LIBRARY_PATH=$CUDA_ROOT/lib:$LD_LIBRARY_PATH
export PATH=$CUDA_ROOT/bin:$PATH
when I try and run the gpu test from the website I get the following error
ERROR (theano.gof.opt): Optimization failure due to: local_log_softmax_dnn
ERROR (theano.gof.opt): node:
GpuElemwise{exp,no_inplace}(<CudaNdarrayType(float32, vector)>)
