 ```bash
 $ python clean.py --format pascal \
->     --annotations_dir /data/datasets/delivery_truck/pascal \
+>    --annotations_dir /data/datasets/delivery_truck/pascal \
 >    --images_dir /data/datasets/delivery_truck/images \
+>    --problems_dir /data/datasets/delivery_truck/problem \
 >    --rename_labels deivery:delivery
