This means that CUDA.jl could not find a suitable CUDA driver. For more information, re-run with the
JULIA_DEBUG environment variable set to
If you encounter this error, there are several known issues that may be causing it:
- a mismatch between the CUDA driver and driver library: on Linux, look for clues in
- the CUDA driver is in a bad state: this can happen after resume. Try rebooting.
Generally though, it's impossible to say what's the reason for the error, but Julia is likely not to blame. Make sure your set-up works (e.g., try executing
nvidia-smi, a CUDA C binary, etc), and if everything looks good file an issue.
Check and make sure the
NVSMI folder is in your
PATH. By default it may not be. Look in
C:\Program Files\NVIDIA Corporation for the
NVSMI folder - you should see
nvml.dll within it. You can add this folder to your
PATH and check that
nvidia-smi runs properly.
Ensure the Visual C++ Redistributable is installed.
