YoloV3 detects nothing

[cedros23]

Hi!

Firstly, thx for the nice effort.
I have compiled your repo and tested with yolov3 however, yolo detects simply nothing, image always shows 0 fps.
Meanwhile, I can work with leggedroboticts darknet-ros 25 fps with nice accuracy already. I use the same ros yaml, launch file and weights.

Do you have any idea to debug the situation?
Thx!

Hello,
Another observation, if I start the node with: rosrun darknet-ros darknet-ros then with more chance detection begins with yolov3.
However, I believe due to threads, if I start the bag file before or in the somehow wrong time, it again detects nothing.

What is the right execution order? I have checked that in the buggy case, node subscribes to camera but somehow detects nothing.

roslaunch darknet_ros yolov3.launch

@cedros23 what package are you using for loading the video feed? video_stream_opencv is recommended.

I too am having issues with this. I am using realsense package and unable to get anything to detect.
