Hello, I’m getting an error while trying to run a script and am getting the following error:
[2024-05-04 19:21:25 UTC][ZED][WARNING] 6: [libLoader.cpp::Impl::293] Error Code 6: Internal Error (Unable to load library: libnvinfer_builder_resource.so.8.6.1: libnvinfer_builder_resource.so.8.6.1: cannot open shared object file: No such file or directory)
[2024-05-04 19:21:26 UTC][ZED][ERROR] Model optimization failed
Any idea?
Already giving a follow up question:
Am I able to wireless broadcast the camera feed to another device within the same network with the zed.enableStreaming(); and init_params.input.setFromStream();?
Hi,
The installer should have run this, but you can manually create the symlink so that the lib can be found;
sudo ln -s /usr/local/cuda/lib64/libnvinfer_builder_resource.so.8.6.1 /usr/lib/x86_64-linux-gnu/
Yes, you can stream the camera feed through the local network wirelessly using these methods, although this requires a bit of bandwidth so a reliable connection is necessary to avoid issues.
Another follow up regarding the streaming
The connection seems to be working as the two devices connect (I also got feedback on the sender machine). But for some reason it breaks after connecting. Could this be related to the bandwith? I’m currently working on wi-fi.
Hi @Rengo
I recommend you try to reinstall the ZED SDK.
Please consider downloading the latest v4.1.1.
If the error persists after the update, please run the ZED Diagnostic tool and send the report file that it generates.
Is there any guide to do this? Sorry fairly new to ZED and linux
ZED_DiagnosticI’ve updated the SDK to 4.1.1 and I’m now getting a different error (progress i think 
)
Getting this error when running the spatial mapping cpp script from the zed-sdk github:

Also, when running nvidia-smi on console I get the following:
Is the ZED sdk wait for a specific version of cuda? If so how can I change it?
Thanks!
(Sorry for the long post)
Hi @Rengo
it seems indeed that CUDA is not installed.
Please reboot and launch again the ZED SDK v4.1.1 installer.
It will guide you installing the required CUDA version.
Hello @Myzhar !
After trying some attempts somehow I got it to work. This is weird because I still keep getting the CUDA not detected error even though I have 12.4 installed according to NVIDIA-smi.
Nevertheless thank you so much to bear with me 
Please note that nvidia-smi shows the newer runtime version of CUDA compatible with the driver, not the installed CUDA toolkit version.
To check the current version of CUDA installed you must use the command /usr/local/cuda/bin/nvcc -V
Got this response with that command:
nvcc: NVIDIA (R) Cuda compiler driver

Seems ok no?
Do ZED Explorer or ZED Depth Viewer work?
I’ve only tested ZED Spatial Mapping and working completely fine.
