this is the code for my project , im having trouble to use my custom data base which called " Butt Pah" .
this code was able to run a default model such as “yolov8” which is a part of the YOLO library.
but i dont figure out how to adjust the code to run on my custom database.

  • it seems that this code would successfuly log into roboflow and download the dataset but i dont know how to use it.
