Why my visualization result is different from the official demo video?

[Yan Tao]

I had downloaded the pretrained weights. I tried to run the visualization code:

python tools/analysis_tools/visualization.py --result-path test/VAD_base_stage_2/Fri_Aug__4_10_18_26_2023/pts_bbox/results_nusc.pkl --save-path work/vis_results

It gave some warning like this one:

/mnt/10t/yantao/adev/p00/VAD/projects/mmdet3d_plugin/core/bbox/structures/nuscenes_box.py:262: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`. In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result.
  fut_coords = fut_coords[[mode_idx]]

But it could generate vis.mp4 file in the destination folder. When I played the vis.mp4 it would display something like this one:

My question is how to generate the video like this one:

Hi,
When I executed the visulation script using the checkpoint provided by the author, an error occured,
Python command: python tools/analysis_tools/visualization.py --result-path test/VAD_base_stage_2/Sat_Sep__9_02_04_54_2023/pts_bbox/results_nusc.pkl --save-path vis_results

Have you ever met this problem? If so could you give me some suggestions to solve this problem? Thank you very much!
