**• my pipeline is : nvinfer->tracker->nvinfer,The first nvifer is object detection, and the second nvifer classifies the results of object detection by performing operations on the 0th class.My requirement is to perform only one classification on the same ID secondary classifier,My operation is to add a probe to the source of the tracker, mark the already classified IDs, and set the class_id of NvDsObject Meta to non-0 (for example, 5), obj ->class_id = 5. However, after setting it to 5, I found that the secondary classifier still classified this target. I added a probe to the source of the second classifier and printed the value of NvDsClassificerMeta. I found that the second classifier still performs secondary classification on the target that I modified to obj ->class_id=5,How can I make the secondary classifier not classify this target?
I set it:operate-on-class-ids=0, I want to make the program only perform secondary inference on targets with the same ID once during the execution process. If the next time the target with the same ID is not changed, how should I proceed? The current method I have come up with is to add a probe to the source of the tracker and process it in the probe. I modified the obj ->class_id in NvDsObject in the probe to set it to 5, but added a probe to the secondary classifier and found that the secondary classifier still classified the target of obj ->class_id=5 in the secondary classification. How should I operate if I want to meet my needs?
That’s what I’m currently doing，I would like to ask why the second level classifier still classifies NvDsObject after modifying its obj ->class_id before the second level classifier?The target category has changed from 0 to 5, why does the secondary classifier still classify this category？
You can refer to our open source should_infer_object in the sources\gst-plugins\gst-nvinfer\gstnvinfer.cpp. There are some conditions for object inferences.
There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
