[Rtk-users] cast itk:::Image to itk::CudaImage

Wed Jan 30 17:33:49 CET 2019

I've encountered the "Cuda Error # 3" issue two times.
As far as I remember, both were caused by the GPU being unreachable at
runtime:
* A missing or outdated (relative to CUDA version) nVidia driver
* The code running within a non-native environment.
The second point can also be triggered if the binary is located on remote
storage.

However, both of these cases were on Windows, and by the path
"/home/tsun/bin/" I would guess you're on some Linux distro.
