This repository contains code demonstrating the Co-learn++ method in our IJCV paper Source-Free Domain Adaptation Guided by Vision and Vision-Language Pre-Training. This is an extension of the Co-learn method in our ICCV 2023 paper Rethinking the Role of Pre-Trained Networks in Source-Free Domain Adaptation.

Prerequisites:

We used NVIDIA container image for PyTorch, release 22.01, to run experiments.

Install additional libraries with pip install -r requirements.txt.

Dataset:

• Please manually download the datasets Office, Office-Home, VisDA-C, DomainNet from the official websites, and modify the path of images in each '.txt' under the folder ./code/data/. Scripts to generate the txt files are in the respective data folders.

Training:

• Training scripts in ./code/uda/scripts. Run eval_target_zeroshot.sh for zero-shot CLIP and train_target_two_branch.sh for co-learning with CLIP encoder.
• Results consolidation scripts in ./code/uda/consolidation_scripts.
