I am able to compile and execute all CUDA samples on my machines and successfully built kernels.ptx

but when I try to startup the backend I get the following error:

22-Nov 13:55:25:INFO:root:Initializing CuDNN backend... error compiling init: could not load module libcuda: dlopen(libcuda.dylib, 1): image not found while loading In[9], in expression starting on line 2

@arshak That is an issue that Julia cannot find the cuda library. I saw you already have DYLD_LIBRARY_PATH set. I guess it might be resolved if you also set LD_LIBRARY_PATH the same as DYLD_LIBRARY_PATH. But there will be a bigger issue: current NVidia cuDNN does not support Mac OS X yet, so the CUDA backend for Mocha is not available on Mac yet.

@arshak OSX is now supported with the latest cuDNN release and latest Mocha :+1:

michael-p commented 9 years ago

@arshak You need to also add /usr/local/cuda/lib to DYLD_LIBRARY_PATH because that's where libcuda.dylib lives on a Mac.

could not load module libcuda: dlopen(libcuda.dylib, 1): image not found #3
