This repo is the official implementation of "SA-Net: Shuffle Attention for Deep Convolutional Neural Networks".

Approach

Figure 1: The Diagram of a shuffle attention module.

Image Classification

We provide baseline sa_resnet models pretrained on ImageNet-1k.

Evaluation

To evaluate a pre-trained sa_resnet50 on ImageNet val with a single GPU run:

python main.py -a sa_resnet50 -e --resume /path/to/sa_resnet50.pth.tar /path/to/imagenet

This should give

 * Acc@1 77.882 Acc@5 93.892
