Hi, I am running the source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8_gpu1.txt demo on gpu-id=1. I noticed that both GPU memory consumption on gpu-id=0 and gpu-id=1. I was wondering what task use gpu-id=0? Can I only use gpu-id=1?
Here is my full config file of source4_1080p_dec_infer-resnet_tracker_sgie_tiled_display_int8_gpu1.txt :
