Why do you have radar in the code?

[sungjuune]

There is nothing mentioned in the paper about radar, but why does the code has radar usage as default?

also, in vip3d_resnet50_3frame.py, the default flag for 'use_radar' is set as False, but the data loader loads radar data.

We need explanation on this.

The dataloader loads both lidar and radar as inputs, but the model does not use them. You can set points = None and radar = None at the beggining of the forward function here during inference, and it will obtain the same evaluation results.
