Question

I'm trying to train a yolo model on custom dataset (object detection) but i'm getting this error
"NoneType object has no attribute keys". I tried changing the dataset.yml file but still getting this.
Can anyone tell me why i'm getting this error and how can i resolve it?

@rohinish404, the error message you're seeing seems to indicate that the config argument passed to train.py function call does not have any keys. This could be caused by an improperly formatted dataset.yaml file, or incorrect data or paths specified in the train.yaml or dataset.yaml files.

Please ensure that your dataset is in the format of YOLO's annotation file style:

path/to/img1.jpg xmin,ymin,xmax,ymax,class_id xmin,ymin,xmax,ymax,class_id ... 
path/to/img2.jpg xmin,ymin,xmax,ymax,class_id xmin,ymin,xmax,ymax,class_id ...

Alternatively, could you provide a more detailed traceback of the error message? A minimum reproducible example would allow us to provide further assistance to you.

The dataset.yml file i created looks like below which i copied from https://docs.ultralytics.com/yolov5/tutorials/train_custom_data/#13-prepare-dataset-for-yolov5 this link. Do i need to make changes here?

[rohinish404]

Solved the error. Thank you so much for the reply:)
