The pycocotools pathway for model validation expects a "Path" object for the data['path'] entry. When the user provides a complete path to a yaml file (or when --dataset-path is provided) this entry remains a string, which leads to an error when doing the pycocotools evaluation.
This is a failure on ultralytics side, but we can fix in the integration since we override the validator class.
Testing plan: The fix allowed me to use "dataset-path" as below:
sparseml.ultralytics.val
--model zoo:cv/detection/yolov8-n/pytorch/ultralytics/coco/base-none
--data coco.yaml
--dataset-path /home/alexandre/datasets/coco
(dataset-path is implemented by 1. copying ultralytics' coco.yaml to the local path, 2. overwriting the dataset path in the yaml file, 3. replacing the data argument with the complete path to edited yaml file.)
