Hi @max,
I glad to see that you are able to advance so much on your own!
Those 6 outputs needs to be connected to the post processing of the network to produce the actual output that you expect.
If your inference system is based on Raspberry pi5, you can take a look here for the full instance-segmentation pipeline, and integrate your specific HEF:
hailo-rpi5-examples/basic_pipelines/instance_segmentation.py at main · hailo-ai/hailo-rpi5-examples (github.com)
If your system is based on x86 platform, you can take a look here:
Hailo-Application-Code-Examples/runtime/python/instance_segmentation at main · hailo-ai/Hailo-Application-Code-Examples (github.com)
Good luck:)
