Different regression loss

We trained with R-50-FPN pytorch style backbone for 1x schedule.

R-50-FPN	L1Loss	4.0	21.4	37.4	config	model | log
R-50-FPN	IoULoss			37.9	config	model | log

R-50-FPN	BoundedIoULoss			37.4	config	model | log

Pre-trained Models

We also train some models with longer schedules and multi-scale training. The users could finetune them for downstream tasks.
