What's the default in ArgoverseMap if map_root isn't passed? I would have expected it to just be None anyway. If that's the case, you could just do:

avm = ArgoverseMap(map_root)

Either way...

If you do not pass the map_root to ArogverseMap, it would be ROOT=Path(__file__).resolve().parent.parent.parent / "map_files".
