Homework Statement
I want to use the Python language in Kaggle to train YOLOv9 on a custom dataset containing three folders: train, test, and valid. Each folder has two subfolders: images and labels. The dataset is installed from Roboflow, using the YOLOv9 model. However, I encountered an error during the training process.

Below, I have attached my code and the error message.

training YOLOv9:
!git clone https://github.com/SkalskiP/yolov9.git
%cd yolov9
!pip3 install -r requirements.txt -q

import os
Home = os.getcwd()
print(Home)

!mkdir -p /kaggle/working/yolov9/weights

%cd /kaggle/working/yolov9

!pip install roboflow

from roboflow import Roboflow
rf = Roboflow(api_key="#my_api")
project = rf.workspace("egat-43h2x").project("parking_lot-1lqk2")
version = project.version(1)
dataset = version.download("yolov9")
The dataset has been uploaded.

training YOLOv9:
%cd /kaggle/working/yolov9

!python train.py \
--batch 16 --epochs 50 --img 640 --min-items 0 --close-mosaic 15 \
--data /kaggle/input/parkingspacesyolov9/data.yaml\
--weights /kaggle/working/yolov9/weights/gelan-c.pt \
--cfg /kaggle/working/yolov9/models/detect/gelan-c.yaml \
--hyp hyp.scratch-high.yaml

I am getting this error:

How to fix?

The above is the last line you showed, so represents the most recent call. It looks to me like the index j is out of range for one or more of the lists.

I have copied the code snippet for uploading the dataset directly from Roboflow for the YOLOv9 model. I installed YOLOv9 and its requirements as mentioned on the official website. Where might the problem be?

Mark just told you. Have you checked the indices and their ranges yet?
