pytorch export to onnx - is there a mapping between the pytorch layer names and onnx layer names?

Question

I am exporting float pytorch model to onnx. In addition I quantize the float pytorch model in native pytorch quantization. My problem is that I need a map between observers names (which come from the pytorch model's layers names) and onnx layers names. I haven't found a way yet to map between the two. Anyone have a solution? Thanks chenru
