Why I have multiple detections at same person?
Screenshot from 2024-08-22 15-24-09

without any modification of code and cfg, will the issue persist?

I don’t change that pgie part.
I just update at tiler_probe. My modification shouldn’t affect pgie.
I’ll confirm with the original code on Monday. In the meantime, if you have idea, pls suggest me.

please try cluster-mode=2.
