Pytorch-yolov3: Training on custom data: Index out of range

[MessiahChen]

Hello.
I was training my custom data on this model.
But here came this error.

/content/drive/My Drive/Colab Notebooks/PyTorch-YOLOv3

    raise IndexError('index {} is out of range'.format(idx))
IndexError: index 0 is out of range

I look throught the related code and Google a lot. Now I am wondering whether _get_item_by_idx is correct

There is a problem with your yolov3-custom.cfg！
Please delete it.
Then
Running script：create_custom_model.sh

I guess you ran this script twice or more。

Thank you! This problem has been solved thanks to your suggestion!
I couldn't imagine it was caused by this.
Thank you a lot!
