Train single class, how I can make dataset

[bhoon1121]

I am training yolov3 model and I have only one class. There were several problems in my case, but I could find solution from other issues. My Question When I trained my yolov3 model, I used 3,000 images and every image have object. I am not sure it is okay to use this dataset for training yolov3 model in single class case. I am wondering that I can make good model if I add images which have not any object.

I think it is important to include the negative examples without the objects. I am doing this and I did not have any problem
