MMDetection V2.3.0 Release

on GitHub

Highlights

• The CUDA/C++ operators have been moved to mmcv.ops. For backward compatibility mmdet.ops is kept as warppers of mmcv.ops.
• Support new methods CornerNet, DIOU/CIOU loss, and new dataset: LVIS V1
• Provide more detailed colab training tutorials and more complete documentation.
• Support to convert RetinaNet from Pytorch to ONNX.
