I run example deepstream-test2 in deepstream_python_apps/apps/deepstream-test2 at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub
I want to get classifier_meta, so I edit deepstream_test_2.py like following, but I found that I could not get classifier_meta_list, it’s always None.
Is there anything wrong?

Hey, can you disable the classifier-async-mode=1 and try again?
