Lane centre polylines in nuscenes after conversion seem to be uncentred wrt map

[samueleruffino99]

Hello, I have converted a nuscenes scenario, and when i am printing out the whole map element I get this strange behavior, the lanes' center lines are not centered with the other map elements. I think it might be an error on how to compute the map_centre of the polylines in converter/nuscenes.utils.py? result[SD.TRACKS], map_center = get_tracks_from_frames(nuscenes, scene_info, frames, num_to_interpolate=5) ....... Normalize place all object to (0,0) map_center = np.array(interpolate_tracks["ego"]["state"]["position"][0]) map_center[-1] = 0 normalized_ret = {} for id, track, in interpolate_tracks.items(): pos = track["state"]["position"] - map_center track["state"]["position"] = np.asarray(pos) normalized_ret[id] = track

I confirmed this error. It is introduced in a recent PR. I have fixed it now. Please pull the latest code
