i keep getting the error at the 3rd epoch. it says cannot create tensor with negative dimension:
I used all the settings untouched as per the repo mentioned. please assist as i have tried the following already:

  • Editing the dataset to a completely new one from Roboflow thinking my dataset was corrupted.
  • Renaming the dataset labels and images to simpler 01.jpg - 01.txt , 02.jpg - 02.txt and so on...

so I believe my dataset should not be the issue as i have downloaded it and tested it with multiple sources from roboflow. I used the format yolo-scaled.

I am also using the mish wewights for implementation. Where can I start to look regarding finding the root cause of the issue? Appreciate the help greatly. error as below from the 3rd epoch before failing:
