How to change the step length or the total denoising steps (N), so that the image generation process could be faster?

Hi there, thank you for releasing the code!

I tried several ways as below to change the step length (delta t) and the total denosing steps but none of them works:

1. Changing the num_timesteps hyperparameter in the config file and changing thetotal_noise_levels accordingly.
2. Changing the step length of the enumeration of i in the SDEditing demonstration function

It seems the synthesized images remain noised after the hyperparameters are tuned. Is there a way to modify N safely? Or is it possible to accelerate the generation process by other means?

Thank you!
