This is a PyTorch/GPU implementation of the paper Mod-Squad: Designing Mixtures of Experts As Modular Multi-Task Learners:

@article{chen2022modsquad,
            title={Mod-Squad: Designing Mixtures of Experts As Modular Multi-Task Learners},
            author={Zitian Chen and Yikang Shen and Mingyu Ding and Zhenfang Chen and Hengshuang Zhao and Erik Learned-Miller and Chuang Gan},
            journal={CVPR},
            year={2023}
}

• The implementation was based on Pytorch==1.10.2 and test on powerpc server.
