mAP is 0

[JamesZhan107]

When i train custom data, the mAP always be 0.(it works well when i use ultralytics/yolov3)

Is there something wrong?

My train command : python train.py --cfg cfg/yolov3-tiny.cfg --data data/coco.data --weights '' --epochs 50 --img-size 416 --device 3

I also encountered this problem, the mAP was always 0 in the process of training my data set.
