@sooahleex @wonjuleee
Thanks for providing this dataset format.
I found 1 stopper issue. Currently, this dataset cannot detect subsets. To align it with other datasets, I would ask you to add possibility to detect subfolders like:

Currently, if I even iterate over subsets and create Datumaro datasets, each for each subset, it will lead to labels mismatch and it cannot be used, unfortunately:


As you can see, labels for train and val are with different indexes.

@sooahleex One more serious problem:
that media (or image) is something weird.

In KITTI datatset image is just a .png file, not PointCloud and the path to that file is also weird. Could you take a look and fix that as well?
