How is the structure of the Tartan datasets arranged during training?

[Tianci-Wen]

Thank you for open sourcing your excellent work. I encountered some problems during training. For one of the sequences, my path is as follows：
～/datasets/TartanAir/abandonedfactory/Easy/depth_left/abandonedfactory/EasyP000/depth_left/xxxx.npy
~/datasets/TartanAir/abandonedfactory/Easy/image_left/abandonedfactory/Easy/P000/image_left/xxxx.png

How can I rearrange the file structure?
Is there any preprocessing after downloading the data set?
Thank you very much and look forward to your answer.
