facebookresearch/detectron2 v0.5 on GitHub

Add “LazyConfig” system, an alternative python-based config system with more flexible syntax and no predefined structures.
Add improved Mask R-CNN baselines to model zoo using large scale jittering and longer training. See blog and configs.
Add backbone wrapper and detector wrapper for models in mmdetection. This allows training and evaluation of these models in detectron2. See an example config that trains a mmdet’s Mask R-CNN
Code release for Implicit PointRend & PointSup.
Code release for Rethinking Batch in BatchNorm.
Add support for RegNet backbones. Example.
Integration of fvcore’s tracing-based advanced flop counter.
New features in DensePose CSE: see its release notes for more details.
