How to prepare the DAIR-V2X data for training?

[linleyzoe]

Hi, thanks for your inspiring work!

There seems no instructions for converting the raw DAIR-V2X to the specific training format, which is referred as root_dir: "/GPFS/rhome/quanhaoli/workspace/dataset/my_dair_v2x/v2x_c/cooperative-vehicle-infrastructure/train.json" in the config file.

Any advice would be greatly appreciated!
