what's the map classes, which have any difference with other objects?

Could you take a short explaination about map class? Thank you very much.

@wycding , in most ego-centric driving datasets like nuScenes, they annotate hd map including lane, road segment, road divider, pedestrian cross and walkway.
For more information, please check nuScenes official website: nuScenes

Thank you for your reply. But I'm still confused about why you conducted the training that every time just focus on one classes? because of the opacity?

I'm also wondering about this. Can't we simply train the model on multiple classes, including pedestrian, vehicle, construction, etc., all at once?

@wycding & @hchoi256, since most of the baselines were evaluated on a single class (which typically yields higher performance), the provided checkpoint is also trained on a single class.
For multi-class training, you can simply extend the model head to include more output classes. However, please note that performance will likely be lower compared to the single-class setting.
