 This repo is a official implementation of ["GCNet: Non-local Networks Meet Squeeze-Excitation Networks and Beyond"](https://arxiv.org/abs/1904.11492) on COCO object detection based on open-mmlab's [mmdetection](https://github.com/open-mmlab/mmdetection). The core operator GC block could be find [here](https://github.com/xvjiarui/GCNet/blob/master/mmdet/ops/gcb/context_block.py). 
 Many thanks to mmdetection for their simple and clean framework.
