To enable SGIE mode, just as this sample [deepstream\_python\_apps/apps/deepstream-test2/dstest2\_sgie1\_config.txt at master · NVIDIA-AI-IOT/deepstream\_python\_apps (github.com)](https://github.com/NVIDIA-AI-IOT/deepstream_python_apps/blob/master/apps/deepstream-test2/dstest2_sgie1_config.txt), the VehicleMake model works in SGIE mode. “process-mode=2” is set in the configuration file to enable “secondary GIE” mode. The other preprocess and postprocess parameters should be configured as the innstruction [DeepStream SDK FAQ - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums](https://forums.developer.nvidia.com/t/deepstream-sdk-faq/80236/21).
