Object Detection CPP sample failed to compile yolo v8 model

[ChrisChang]

I'm trying to use the Object Detection CPP sample from Model Zoo.

(OpenVino ver. 2025.2)

(see https://github.com/openvinotoolkit/open_model_zoo/tree/master/demos/object_detection_demo/cpp

)

It works well for loading the models in the models.lst.

Now I got a fine-tuned AI model based on Yolo V8, it works well with my own Python script.  

And I'd like to to do this with CPP sample code (https://github.com/openvinotoolkit/open_model_zoo/tree/master/demos/object_detection_demo/cpp).

But I encounter the exception while thr code ran into the function

"logBasicModelInfo" in "common.hpp",

The exception occurs at 

"const std::string name = output.get_any_name();"

Looks some kinds of NULL when loading info from ov::Output.

What can I do for adding the required information into model?

Or should I modify the OpenVino library?

Hi ChrisChang,

Thank you for reaching out to us.

Could you please share your YOLOv8 model so I can take a look at the issue further?

Hi:

Any update?

Hi ChrisChang.

To integrate a custom model with Open Model Zoo Demos, you need to modify the demo's source code to fit your model. It is better to use a minimal C++ example to start. Therefore, I suggest you refer to the YOLOv8 OpenVINO Inference in C++.
