Hi,

I installed the latest version of ZED SDK, 5.2. and when I do “import pyzed.sl”

I got an error that
Python 3.12.3 (main, Jan 22 2026, 20:57:42) [GCC 13.3.0] on linux Type “help”, “copyright”, “credits” or “license” for more information. >>> import pyzed.sl Traceback (most recent call last): File “”, line 1, in ImportError: /home/jay/work/sensors/.venv/lib/python3.12/site-packages/pyzed/sl.cpython-312-x86_64-linux-gnu.so: undefined symbol: _ZN2sl9CameraOne8isOpenedEv

Does anyone know how to solve this issue?

Thanks.

Hi,

Sorry about that, the deployement script had an issue, this was taking a previous incompatible version. It’s now fixed, you can retry

It still has a problem. During the installation, I got an error when optimizing NEURAL depth modes that
[2026-02-11 22:00:05 UTC][ZED][ERROR] sl_ai library loading failed details: libnvidia-encode.so.1: cannot open shared object file: No such file or directory

I tried install nvidia-utils-590 since I am using nvidia-driver-590 but I got an error that
dpkg: error processing archive /var/cache/apt/archives/nvidia-utils-590_590.48.01-0ubuntu0.24.04.1_amd64.deb (–unpack):

I didn’t these errors when I tried to install ZED SDK 5.1.

Thanks.

Problem Solved!

The import error has been resolved with the new installer. Thanks adujardin. Regarding the driver and library issue, I found that when CUDA 13.0 is not installed, the ZED SDK attempts to install libnvidia-580, even if the NVIDIA driver version is 590. This caused conflicts and disrupted my system setup.

To avoid this issue, CUDA 13.0 should be installed before installing the ZED SDK. Alternatively, the system should use NVIDIA driver version 580 instead.
