SimMatchV2: Semi-Supervised Learning with Graph Consistency (ICCV2023)

This repository contains PyTorch evaluation code, training code and pretrained models for SimMatchV2. Most of the code in this repository is adapt from here.

For details see SimMatchV2: Semi-Supervised Learning with Graph Consistency by Mingkai Zheng, Shan You, Lang Huang, Chen Luo, Fei Wang, Chen Qian, and Chang Xu

Reproducing

To run the code, you probably need to change the Dataset setting (ImagenetPercent function in data/imagenet.py), and Pytorch DDP setting (dist_init function in utils/dist_utils.py) for your server environment.

The distributed training of this code is based on slurm environment, we have provided the training scrips in script/train.sh

We also provide the pre-trained model.

	Arch	Setting	Epochs	Accuracy	Download
SimMatchV2	ResNet50	1%	300	71.9 %	300ep-res50-1p.pth
SimMatchV2	ResNet50	10%	300	76.2 %	300ep-res50-10p.pth

If you want to test the pre-trained model, please download the weights from the link above, and move them to the checkpoints folder. The evaluation scripts also have been provided in script/train.sh
