Acknowledgements

This implementation is based on the codebase provided by SPO, D3PO, Diffusion-DPO, Diffusers and PickScore. The public availability of them significantly facilitated our research, and we gratefully acknowledge their authors' contribution.

🔧 Training

Please refer to the README.md in the folder "./training"

🔧 Example: have a try

Before running the example file, please ensure that you have completed the environment configuration in "./training/environment.yaml".
