Hi @<1651395720067944448:profile|GiddyHedgehong81>

However I need for a yolov8 (Object detection with arround 20k jpgs and .txt files) the data.yaml file:

Just add the entire folder with your files to a dataset, then get it in your code
Add files (you can do that from CLI for example): None

clearml-data add --files my_folder_with_files

Then from code: None

data_path = Dataset.get(dataset_name="my dataset", alias="training dataset").get_local_copy()

# now all my files are in `data_path`
