Neural depth mode leads to crash

After resolving zlibwapi.dll error I met this

what the platform you support most? i can switch to ubuntu if it’s more stable

Hello,

It may be an OpenGL error rather than a NEURAL mode issue. To be sure of that, you can run our tutorial 3 after changing the depth mode to neural.

Either way, there is probably an issue with your nvidia / cuda installation. Getting a fresh installation (windows or ubuntu) should fix this. If you use windows, don’t install 3.7.5, we fixed a CUDA issue in 3.7.6.

Hi, thank you for answer
I’ve already had cuda before installed ZED sdk but I clicked install cuda while ZED sdk has been installing. Reboot. There were issues. I removed old cuda. I installed last correct nvidia driver for my “quadro” graphic card. Reboot.
All but neural mode became working. Then I resolved zlibapi.dll problem and net for depth was optimized successfully.

I have last driver and last cuda
Driver Version: 516.59 CUDA Version: 11.7

Checked the same functionality on different WS under ubuntu, works with Quadro 8000 Driver Version: 510.73.08 CUDA Version: 11.6

may the problem be connected with 11.7 version?
