Unable to optimize models on SDK 3.8

Software
1

Hi,

I wanted to download and optimize all the ai models to test the object_detection feature provided by the ZED tools. My system configuration is,

Camera → ZED 2i
Platform → Nvidia Jetson AGX Xavier
OS → Ubuntu 20.04
CUDA → 11.4
ZED SDK → 3.8.2

Below is the problem I am facing,

/usr/local/zed/tools/ZED_Diagnostic -aio

Optimizing all AI models
Optimizing: MULTI CLASS DETECTION…
Optimized model not found, trying to download it…

Can you please help me resolve this problem.

Hello,

Can you remove everything from the folder /usr/local/zed/resources and try again ?

Hello Antoine,

I removed all the contents of /usr/local/zed/resources and tried. Below is the result of it,

/usr/local/zed/tools/ZED_Diagnostic -aio

Hello Antoine,

Can I get some suggestions on this. I am not able to use the object detection feature or the neural mode on this setup (Ubuntu 20.04 + ZED SDK 3.8).

Thanks,
Shalini
