There is a problem with the graphics driver or with this GPU
device. Be sure that you have a supported GPU and that the latest
driver is installed.
The CUDA driver could not be loaded. The library name used was
'/usr/local/cuda/lib/libcuda.dylib'. The error was:
dlopen(/usr/local/cuda/lib/libcuda.dylib, 10): image not found
