YOLOv8 export to Tensorflow lite

Hello!
I try export trained YOLOv8s model to Tensorflow Lite format.
Train dataset have 213 classes. Converted to TFLite model have input (1,1280,1280, 3) shape
and output (1, 217, 33600) shape.
How to to extract predicted bounding boxes and class conf from the tensor output?
Thank you!

I am also in a similar situation. I am trying to use a Yolov8 trained model in NatML’s Unity API. I am getting results back but not in a form I understand. I’d prefer not to have to replicate the entire Ultralytics API in C# so if there’s a decent guide on how to understand the tensor values that are returned and how to process them into class, bounding box, etc. I would greatly appreciate it.
