How do I fine-tune the official Re-ID model?

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) GPU Ubuntu
• DeepStream Version 6.2
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs) Question
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description) Gst-nvtracker

My goal is to fine-tune the official Resnet 10 model trained on Mars dataset using KITTI Dataset. Is it possible to do it? Or use a completely new Re-ID model?

Can you share the link which the model you are using? Yes, you can use your own ReID model based on guide here: Gst-nvtracker — DeepStream documentation

But one of the answers said Deepstream supports custom onnx modules only from 6.3 onwards. I cannot update to that.

Seems you have similar topic here: Re-ID model engine failing in Deepstream 6.2 - #8 by kesong.
