Deepstream python apps using TAO Faster RCNN model trained on COCO bug with class attributes

Hi,

I deploy my TAO Faster RCNN model trained on 80 class COCO dataset using Deepstream with tracker. I want the tracker to only track person class. Therefore, I set the pre-cluster-threshold=1.0 for all the classes in the Deepstream_config file frccn_res50_test_pgie_config.txt except the person class which is class_number 49 as per labels2.txt (see attached files).

However, this works for all the classes except class-0. If I set the pre_cluster_threshold=1.0 for class-0 (aeroplanes), deepstream does not generate any bbox. If I comment this line out, it works fine but it also detects + tracks aeroplanes which I do not want. From my understanding, the threshold value for class-49 (person class) and class-0 (aeroplane) seem to somehow getting linked.

Please provide complete information as applicable to your setup.

labels2.txt (617 Bytes)

Is there other component that need the class except person?
If there is not, you could use “filter-out-class-ids” in nvinfer plugin to filter out the objects of other classes.

Thank you, filter-out-class-ids works like a charm!
