[image] ayanapple1: what can be the reason for the negative confidence? is that an export issue? is the negative confidence reasonable? is this a wrong bboxes? are all bboxes wrong? If there is model accuracy issue, please refer to this faq .

please refer to sources/tracker_ReID/README in DeepStream SDK for how to prepare resnet50_market1501.etlt, which will be converted to the modelEngineFile.

I have set up by following that but during runtime the engine file is not being generated.

@fanzh do i need to install any tao packages inside my container?

[image] ayanapple1: I have set up by following that but during runtime the engine file is not being generated. could you share the result of “/opt/nvidia/deepstream/deepstream/samples/models/Tracker”? could you a share a complete running log?

Hi , the issue was sorted but now objects with same object id doesnt has obj_meta.obj_user_meta_list in different frames . therefore the embedding vector is not generated every frame for same object. i have set reidExtractionInterval: 1 , evethough same result .can you tell me what is causing this? …

which sample are you testing or referring to? what is the complete media pipeline? where di you add the probe function? do you mean obj_meta.obj_user_meta_list is empty? Since nvtracker plugin is opensource, you can add logs in NvTrackerProc::updateFrameMeta to check.

I am using the tao re-identificationnet on ships to generate embedding vector for re-id . i added the probe function just after the tracker . some objects are not generating vectors in random frames. the same object is able to generate vector in other frames. can it be due to some config issue or th…

please refer to my last comments. do you mean obj_meta.obj_user_meta_list is empty? or obj_meta.obj_user_meta_list is not empty, but pReidObj->ptr_dev/pReidObj->ptr_host is empty? could you share a running log? wondering if there are some abnormal logs. can you use deepstream-test2 to reproduce thi…

1.obj_meta.obj_user_meta_list is empty is empty for some objects leading to no generation of the re-id vector while its available for some objects.

plesae try “reidExtractionInterval: 0”. reidExtractionInterval means “Frame interval to extract ReID features per target for re-association; -1 means only extracting the beginning frame per target”.
