ZED_Depth Tool - Low Video Memory - RTX 3090 - Ubuntu 20.04

When running the ZED_Depth_Viewer tool on Linux, I get an out of GPU Memory error. Perplexed, since I’m using an RTX 3090, with no other applications running. See the attached screenshot. (https://i.imgur.com/pLFFNZL.png). Screenshot shows GPU specs (bottom left), camera sensor details (bottom right), and a couple of error logs from the Depth tool (top right).

I can compile and run the depth example from github without errors.

System details:
Linux (Ubuntu 20.04)
NVIDIA Driver Version: 495.29.05 CUDA Version: 11.5
RTX 3090 (eGPU, via Razer Core X Chroma - Thunderbolt )
ZED SDK v: Ubuntu20_cuda11.4_v3.6.1

Could it be I’ve installed Cuda 11.5, and the SDK is built against 11.4?

I had a similar issue. In my case, the problem was that I have Intel and Nvidia cards in my laptop. The ZED software used intel card instead of Nvidia. The issue occurred when I run it from docker container.
I use Manjaro Linux and solution for me was to switch for permanent usage of Nvidia GPU using optimus manager:

In your case (Ubuntu) there is something called prime-select, try googling it.

@g7T in your case CUDA can be the problem. CUDA 11.5 is indeed not yet supported
