Varifocal Loss for YOLOv5

[lascreia]

Good day,

I am experimenting and trying to use the varifocal loss for YOLOv5 but i get the error "AssertionError: Only sigmoid varifocal loss supported now."

How do I use varifocal loss for YOLOv5? Is it possible?
Thanks in advance

If you would like to use varifocal loss in yolov5, you should know what the varifocal loss is and what it is used for (in general the varifocal loss works with IACS, which means you need to define right learning targets). Please read our paper for it.
