Problem description:
Hi Sir/Madam:

I am trying to read the example code called “deepstream_test_2.py”. However, it looks like, the codes inside did not actually use the second and third DL models (vehicle color/make/type).

Codes under “osd_sink_pad_buffer_probe” are still using object detection algorithm only.
I am wondering whether you could provide me several lines of python codes or related link of how to use sgies.
Thanks a lot.

Best
Yichao
