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 As far as I remember, both were caused by the GPU being unreachable at runtime: * A missing or outdated (relative to CUDA version) nVidia driver * The code running within a non-native environment.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. /Andreas __________________________________ Andreas Gravgaard Andersen Department of Oncology, Aarhus University Hospital Nørrebrogade 44, 8000, Aarhus C Mail: agravga...@protonmail.com Cell: +45 3165 8140 On Wed, 30 Jan 2019 at 17:29, Simon Rit <simon....@creatis.insa-lyon.fr> wrote: > Can you send the code if you want us to help? > > On Wed, Jan 30, 2019 at 5:21 PM tao sun <colddie...@gmail.com> wrote: > >> No I am not using that.
