I have read the model configuration file config.json used during training with the nuScenes dataset in the code.

I found that when the robot future is included, the pred_state only contains the vehicle parameter and does not include the pedestrian configuration.
However, in the configuration files for other cases, the pred_state includes both pedestrian and vehicle parameters.

Why is this the case? What does it imply? Does it mean that when the robot future is included, only vehicle trajectories can be predicted and pedestrian trajectories cannot be predicted?

when encoing robot future:
/Trajectron-plus-plus/experiments/nuScenes/models/robot/config.json

 "pred_state": 
    {
        "VEHICLE": 
        {
            "position": ["x", "y"]
        }
    }, 

others:
for example: /Trajectron-plus-plus/experiments/nuScenes/models/int_ee/config.json

"pred_state":
    {
        "VEHICLE": 
        {
            "position": ["x", "y"]
        }, 
        "PEDESTRIAN": 
        {
            "position": ["x", "y"]
        }
    },
