Would like to ask you YOLOv5-Seg custom function

[FuHTong]

First of all, thank you for checking my question. I have two difficulties at present：
First of all, when I set output-instance-mask=1, my program will exit automatically and display core fault of the Segmentation. However, I don't know what happened but I know that I haven't been dumped into the probe of pgie.
The second problem is that when I set output-instance-mask=0, I can run normally and enter the probe, but the classID and other results I get are wrong.
Can you correctly obtain the relevant data of obj in the probe? In addition, in the custom function you provided, the engine model of YOLOv5 only has two outputs, which I don't quite understand. May I ask if you use the official model?
Thank you very much!
