https://github.com/PJLab-ADG/DetZero/blob/main/refining/detzero_refine/datasets/waymo/waymo_geometry_dataset.py#L74 This line of code may cause a bug. If a trajectory smaller than self.query_num(3) appears at a certain position in the dataset, then self.query_num will be permanently set to...

Problems may arise when processing long time series trajectories.
