How to create the pickle files for my own dataset?

[henry81003003]

Hi @JakubSochor, thanks for your research on 3D bounding box estimation.
I have a problem and it's the same as the topic.
I'd like to create those pickle files for my own dataset, but I have no idea what is the format of those pickle files.
Can you give me some tips for doing this work, especially for dataset.pkl and atlas.pkl?

Thanks in advance
