Panoptic Implementation

[zachcoleman]

Does anyone know why the loss is configured like this for the panoptic fpn seg head?

mmdetection/mmdet/models/seg_heads/panoptic_fpn_head.py

Lines 65 to 67 in 9d3e162

	loss_seg=dict(
	type='CrossEntropyLoss', ignore_index=-1,
	loss_weight=1.0)):

This is the only place in the repo that this occurs.
