Hello guys, currently I’m dealing with this problem. I’m trying to run this code zed-sdk/camera control/python at master · stereolabs/zed-sdk · GitHub . I’ve tried to reinstall everything multiple times but still problem with neural depth. Can you provide me some installation guide? I’ve tried downloading tensorRT and adding it to path but without success.
Hi @nehovortake

This can be the cause of the problem. The ZED SDK installs the required TensorRT libraries.
I recommend you manually install the ZED SDK, CUDA, any installed NVIDIA library, and the GPU driver.
Then reboot and reinstall the latest GPU driver (not CUDA).
Finally launch again the ZED SDK installer and let it install CUDA and the NVIDIA libraries.
Is this big issue?
In next window NVIDIA Installer has finished every Component has Status Installed
Ive deleted everything, reinstalled zed sdk, got only warning to install CUDA and get this from diagnostic
Please can you provide me detailed step by step guide as it seems like what Ive installed is still not working. Still got the same error. In this path C:\Program Files\NVIDIA GPU Computing Toolkit are both CUDA and TensorRT-10.14.1.48. Even GPU is updated to latest.
The screenshot only shows that the software is not correctly installed, not why.
Please save the report and share it.
I recommend you read the ZED Diagnostic documentation and the Get Started on Windows documentation.
Please also be sure that secure boot is not enabled in the BIOS of your laptop.
Once Ive installed CUDA it was ok. Ive tried using GPT in this case and his advice is that for zed sdk 5.x I have to use CUDA 12.x not 13.x and tensorRT 8 not 10. Is this true?
I believe the information on our Download page is more accurate than that provided by ChatGPT.
TensorRT 8 must be used with old GPU models. You have an “NVIDIA GeForce RTX 3050 6GB Laptop GPU,” which supports CUDA 13 and TensorRT 10.
Have you checked “Secure Boot” as I told you before?
Yes. Still the same problem with tensorRT.
Im clueless. Your advice didnt work, Ive tried Stereocolab assistant to navigate me trough installation process that also didnt work. And finally made sure the paths are correct and still same result.
I really need this to work as it is ment for my Diploma thesis. I have everything ready but this camera refuses to work when it comes to neural depth.
Have you tried what’s described in this thread?
