ZeroDivisionError: division by zero

[abhay-iy97]

Hi @DiaaZiada I'm trying to train Yolov3 on a custom dataset for object counting but I'm running into this issue (ZeroDivisionError: division by zero) in the first epoch of training.

Data folder structure is as mentioned in the README and as followed from here: https://medium.com/@anirudh.s.chakravarthy/training-yolov3-on-your-custom-dataset-19a1abbdaf09

data/

• images -- 1.jpg -- 2.jpg -- 3.jpg
• labels -- 1.txt -- 2.txt -- 3.txt
• obj.names (list of 18 class names row wise)
• test.txt
• train.txt

config/

• obj.data

classes= 18 train = data/train.txt valid = data/test.txt names = data/obj.names backup = backup/

• yolo-obj.cfg (Made changes in this file as mentioned in the medium.com link shared above) Full stack trace:

  Traceback (most recent call last): File "train.py", line 89, in loss = model(imgs, targets) File "C:\Users\++\AppData\Local\Programs\Python\Python37\lib\site-packages\torch\nn\modules\module.py", line 722, in _call_impl result = self.forward(*input, *kwargs) File "C:\Users\++\Object-Counter-YOLOV3\util\model.py", line 73, in forward print(module[0](x, targets)) File "C:\Users\++\AppData\Local\Programs\Python\Python37\lib\site-packages\torch\nn\modules\module.py", line 722, in _call_impl result = self.forward(input, **kwargs) File "C:\Users\++\Object-Counter-YOLOV3\util\moduler.py", line 128, in forward precision = float(nCorrect / nProposals) ZeroDivisionError: division by zero

Any idea what could be going wrong?
