about algoverse2 pkl and eval problem

[wengdunfang]

I have used your code (python tools/create_infos_av2/create_av2_infos.py) to generate av2_val_infos_mini.pkl. However, I noticed that several cameras are empty, such as
'ring_front_left': None,
'ring_front_center': None,
'ring_rear_right': None
in 'scene_id': '02678d04-cc9f-3148-9f95-1ba66347dff9'.
Could you please provide me with a genuine pkl file? Thank you.

If I use the pkl generated by me for inference, there is an error:

bash tools/dist_test.sh projects/configs/far3d.py /mnt/far3d/iter_82548.pth 4 --eval bbox

File "/mnt/Far3D/projects/mmdet3d_plugin/datasets/argoverse2-dataset_t. py", line 250, in __ getitem__

TypeError: 'NoneType' object does not support item assignment

This is because some cameras are empty.
