Error When `variation_degree_schedule` Value Exceeds 10 about dpsda HOT 1 CLOSED

Thank you for your message. The reason of the error is as follows.

In your script. timestep_respacing is set to ddim10. This means that there is only 10 steps in the diffusion sample generation process.

Let's say the i-th number in variation_degree_schedule is a. It means that at i-th iteration of PE, the generation will only use the last 10-a diffusion sampling steps. Therefore, all the numbers in variation_degree_schedule should be <=10.

If you want to use the variation_degree_schedule you set there, you can consider changing timestep_respacing to a larger number, such as 100 and ddim100. (For the difference between {x} and ddim{x}, please refer to this repo https://github.com/openai/improved-diffusion?tab=readme-ov-file#sampling.)

Feel free to reopen the issue if you have further questions.
