Update ValueError message for ground truth line.split() in line 392.
Reason: extra/ folder no longer exists, no script \"remove_space.py\" or \"rename_class.py\" found. The error may occur if more data are packed into the line, not only when class_name has spaces.
Changes: removed the run-script hint. Add line length to show error explicitly.
