Readme steps are not elaborated

[sguttikon]

Hi, could you please elaborate more in detail reproducing steps. Such as for the 'Data Generation' step its not clear currently -

1. from where 'train_scans.txt' 'validation_scans.txt' files coming from they are not present in 3dssg.zip file
2. how are 'labels.instances.align.annotated.v2.pkl' generated
3. where is this 'obj_attr.pkl' file coming from ?

Hi, please find my answers here :

1 & 2 : These files are available with download of the 3RScan dataset.

3 : The obj_attr.pkl is available with the provided meta downloads.

Both links are provided in the "Downloads" section of the README - here. Hope this helps!

What about align.annotated.v2.ply @sayands ?

You need to use the repo from here, updated the README. Thanks for pointing out!
