error loading custom checkpoint

[niallomahony93]

I got this error when using my own pointnet2_semantic checkpoint -

(0) Not found: Key Fsem/biases not found in checkpoint [[node save/RestoreV2 (defined at train.py:133) ]]

Has anyone any clue how to solve it? This repository seems to be built off pointnet2 but I now get the feeling that a pointnet checkpoint may be required, that or a checkpoint from training with the part_seg script is required.
