Description
In yolov3-10.onnx (from https://github.com/onnx/models/tree/master/vision/object_detection_segmentation/yolov3 ), the post-processing part includes 6 loops. The trip counts are 13, 13, 26, 26, 52 ,52, respectively.
The loops uses scan outputs. The problem is, by ONNX definition, loop output is like "[1, 2, 3, 4...TripCount].
However, for this model, it expects the output to be like "[0, 1, 2, 3, .. TripCount-1]"

Research direction
Start with yolov3-10.onnx from the linked ONNX Models path and inspect the six post-processing loops with trip counts 13, 13, 26, 26, 52, and 52. Compare their scan outputs with ONNX Loop output semantics, especially whether the model expects zero-based values. Done means the loop-output indexing is consistent with the ONNX definition.
