ZED_Depth_Viewer not work

my first time to run the tools/ZED_Depth_Viewer on Ubuntu18.04, cuda10.2, zed sdk version is 3.7.6

In addition, the ZED_Explorer works normally

has anybody know how to solve it?

ubuntu@ubu:/usr/local/zed/tools$ ./ZED_Depth_Viewer

Hi @mrhuang
please run the ZED_Diagnostic tool and send the report file that it generates to support@stereolabs.com.

also the same problem when it runs to the AI Models

Please try to run it without the GUI:
$ ZED_Diagnostic -c

OK~it’s works, should I reinstall the zed sdk?

The problem with your configuration is that you are using CUDA 10.2 with an RTX GPU card.
I suggest you uninstall CUDA, download the ZED SDK v3.7.7 for CUDA 11.7, and let the installer guide you to install the required CUDA version.

emmm…its hard to reinstall CUDA because other software should run in 10.2

But I can use SDK to get point cloud data in my code, just can’t run ZED_Depth_Viewer to see the picture of point cloud

Can I use previous releases of the ZED SDK?
