@lesun90 what AI model are you using? I suggest you use ZED_diagnostic to download/optimize the models before using them:

$ ZED_Diagnostic --help
Usage:
    -d | Auto start the diagnostic (only for GUI mode)
    -c | Start the application in command line (Useful when no GUI is available)
    -aid | Download all models for the object detection module
    -aio | Optimize (and download if needed) all models for the object detection module
    -aic | Clear all models for the object detection module
    -ais X | Download and Optimize the associated sl::DETECTION_MODEL (int)
    -nrlo | Download and Optimize the NEURAL depth mode
    -r | Recover an MCU module with not valid serial number
    -h | Display this help

Use the -aio flag with the model number. If you are using the NEURAL depth mode do not use the -nrlo flag, but use -ais 8 because there is a bug with -nrlo that will be fixed in v3.7.1

Thank for great and quickly support. Really impressed and appriciaited. Still not sure my the model not download from ros script. And that tool "ZED_diagnostic" is really helpful.

Thanks for your answer, which will help to solve my problem. However, what is the " model number" when I use -aio flag or where can I find the number? thanks!

@interqhq please never reply to a closed issue. It's better if you open a new issue and you cite the existing closed issues.

However, the AI_MODELS are defined here: https://www.stereolabs.com/docs/api/group__Object__group.html#gaf90fcebb970fc56cb9963d1a8b91a8d1 the first has index 0, the last 8
