Darknet: Yolov4-tiny_3l for small and large object?

[nguyenanhtuan1008]

I would like to train the model on Yolov4 tiny with small and large objects. But I found in respo only Yolov3-tiny_3l.cfg: https://raw.githubusercontent.com/AlexeyAB/darknet/master/cfg/yolov3-tiny_3l.cfg

@AlexeyAB Can you update the config file for this?

Thank you so much!

Sorry I have another question about anchor calculation in this yolov3-tiny_3l.cfg:
Which dataset did you use for anchors calculation? COCO dataset?
anchors = 12, 16, 19, 36, 40, 28, 36, 75, 76, 55, 72, 146, 142, 110, 192, 243, 459, 401

I have try to do it with my custom dataset by command:
darknet.exe detector calc_anchors data/obj.data -num_of_clusters 9 -width 416 -height 416

But when I training the model the mAP seen less than your default anchors around 1%.
