CUDA 12.1 not ready message

The ZED Diagnostic tool under ZED SDK says “CUDA 12.1 not ready” but the command line nvcc --version says I’m runing cuda_12.1.r12.1. Can I disregard this message?

As the message says, a restart is required. Cuda installation requires a system reboot.

I took that screenshot after the reboot. Didn’t help.

Hi @CFC
have you tried to launch the ZED Explorer and the ZED Depth Viewer tools?
Do they run correctly?

Just restarted the computer again, both ZED Explorer and Depth VIewer work fine, still have the Cuda error though in the diagnostic tool.i

If ZED Depth Viewer works correctly you can ignore the ZED Diagnostic warning.
What version of the SDK is it? This information is normally available in the report
