Hi @lol - just double-checking, but I’m curious as to why the update to include the dataset download code in model.train()?

That code snippet is for downloading the dataset, and it returns a Dataset object

To get this to run, you’ll want to run the notebook, as originally configured - with the download code separate from the model training code:

  • Dataset download
!mkdir {HOME}/datasets
%cd {HOME}/datasets

!pip install roboflow --quiet

from roboflow import Roboflow
rf = Roboflow(api_key="YOUR_API_KEY")
project = rf.workspace("roboflow-jvuqo").project("football-players-detection-3zvbc")
dataset = project.version(1).download("yolov8")
  • Training code updates (if you’d like to run it in the format you have above), see my screenshot below for an example of it running:
from ultrayltics import YOLO

model = YOLO('yolov8m.yaml')

model.train(data='INSERT_PATH_TO_DATA_YAML-FILE', imgsz=INTEGER_RESIZE_VALUE, epochs=1, device=0)

Note that you’ll want to train for far more than 1 epoch. Train for a minimum of 25 epochs.

I also recommend explicitly setting the imgsz parameter, based on the square resize value you generated your images with: Image Preprocessing - Roboflow
