How are planes labeled in the plane segmentation mask branch?

Hi, I have read your paper, but I'm confused about the way the planes are labeled from 1 to 10 (if 10 planes are found), and I haven't got a clue for that. Are they labeled according to the order of their covered area, or from left top to right bottom, or just labeled randomly?

They are random. The order of planes doesn't matter since I used the matching loss.

Great work!
when I try to train the network an error shows up: NotFoundError: ./tf_nndistance_so.so: undefined symbol: _ZTIN10tensorflow8OpKernelE.
I think this may be because I didn't successfully build the code.
How can I eliminate this problem？

Thanks in advance!!! @art-programmer
