We provide config files to reproduce the results in the paper for
"GCNet: Non-local Networks Meet Squeeze-Excitation Networks and Beyond" on COCO object detection.
GCNet is initially described in arxiv. Via absorbing advantages of Non-Local Networks (NLNet) and Squeeze-Excitation Networks (SENet), GCNet provides a simple, fast and effective approach for global context modeling, which generally outperforms both NLNet and SENet on major benchmarks for various recognition tasks.

denotes Global Context (GC) block is inserted after 1x1 conv of backbone.DCN
denotes replace 3x3 conv with 3x3 Deformable Convolution in c3-c5
stages of backbone.r4
and r16
denote ratio 4 and ratio 16 in GC block respectively.检测开源算法工具包
