@wenku1992abc Hi,

• There is not easy way to use multi-GPU for detection on the single video-stream
• You can use 2nd GPU for Tracking:
  
  
  
  1. just uncomment this line: https://github.com/AlexeyAB/darknet/blob/ea09a6e0b38e1ddf43ffcd81d27f0506411eb8e4/src/yolo_console_dll.cpp#L16
  
  
  2. and change this line to Tracker_optflow tracker_flow(1);: https://github.com/AlexeyAB/darknet/blob/ea09a6e0b38e1ddf43ffcd81d27f0506411eb8e4/src/yolo_console_dll.cpp#L112
  
  

So Detection will be on the GPU#0, and Tracking will be on the GPU#1.
