I run two stages model with deepstream, second model use primary’s output.
after run two times, wo found the resul in primary are same, but the result in secondary-gie0 are different.
the config file:
#Required by the app for OSD, not a plugin property

need more information, which deepstream sample are you testing? did you modify the code, models? how did you get the results above?
yes, i change some code,but i don’t change the inference parts, I will confirm in original codes.
the log was print in gst-dsexample:
for (l_obj = frame_meta->obj_meta_list; l_obj != NULL; l_obj = l_obj->next)
obj_meta = (NvDsObjectMeta *)(l_obj->data);
gint src_left = GST_ROUND_UP_2((unsigned int)obj_meta->rect_params.left);
gint src_top = GST_ROUND_UP_2((unsigned int)obj_meta->rect_params.top);
gint src_width = GST_ROUND_DOWN_2((unsigned int)obj_meta->rect_params.width);
gint src_height = GST_ROUND_DOWN_2((unsigned int)obj_meta->rect_params.height);

which deepstream sample are you testing? did you modify the models? what is the whole media pipeline? can you use deesptream native sample to reproduce this issue? deepstream-test2 supports pgie+sgie.
I found same problem
in nvcr.io/nvidia/deepstream :6.1-triton after two time in source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt ,
I just modify the source4 to source0, and add print in ds-example.txt

Using the same cfg, code patch with yours, I can’t reproduce this issue on T4 deepstream6.1, here are code, test results.

thanks very much, the problem was fixed , the reason :classid is not assigned . it is a random, the box was dropped when the value>num-detected-classes.
