I'm trying to use my own custom tflite model for person detection in voxl m500 model.
I updated the system and still after changing the  path of the model in config file of tflite server I can't see any detections on voxl-portal.
Also, please provide some guide to write my own post processing function through inference class for the same.

We don't have a guide on our own, but Google should have plenty of guides and examples

You'll need to add your own post processing function in [this area of the code](https://gitlab.com/voxl-public/voxl-sdk/services/voxl-tflite-server/-/blob/master/src/main.cpp#L203)

Here is Google's guide on how to postprocess tflite data
