[Bug: datav1.py] The loaded semantic labels are bugged

[GregorKobsik]

Description:

I suppose, that the code in datav1.py has a bug in line 572. The returned semantic labels are a concatenation of all parent node labels down to the leaf node. This results in errors in the visualization script vis_pc.ipynb, especially in vis_utils.py in function draw_partnet_objects(...) in line 240 color = sem_colors[part_sems[jj]

Solution:

DSG-Net/code/datav1.py

Line 572 in 6c6d117

node.full_label = parent.full_label + '/' + node.label

You can fix it by replacing the code with:
node.full_label = node.label

Expected output (after fix)

Can anyone confirm this bug, too?
