Missing config file for export_nusc_2_preview_format.py to prepare nuScenes dataset

[woter21]

I am attempting to evaluate the CTSD pipeline using the nuScenes dataset. The documentation mentions using a layout resource package (e.g., nuscenes_scene-0627_package.zip) which contains 3dbox, hdmap, and rgb data.

I would like to organize my own nuScenes data into this specific format. I found the script export_nusc_2_preview_format.py in the repository, which appears to be intended for this purpose. However, the script requires a configuration file (or specific arguments) that is currently missing or undocumented.

Could you please provide:

The missing configuration file or an example command line for export_nusc_2_preview_format.py?

Any specific requirements for the data.json structure that the pipeline expects?

Thankyou very much！
