Because DPM-Solver is an ODE-based solver so it does not add noises at the intermediate steps. I also implemented SDE-based DPM-Solver here: https://huggingface.co/docs/diffusers/en/api/schedulers/multistep_dpm_solver

To all: I haven't solve it yet... :(

Hi @Taonanana , Sorry for the late reply. I don't exactly understand the question you're asking. Could you please give me a more detailed explanation?

Of course. Please check https://github.com/AUTOMATIC1111/stable-diffusion-webui , where all the samplers starting with "DPM" are dpm-solver (with different settings). As far as I known, the best are "DPM++2M" and "DPM++2M Karras",...

Hi @jianghuyihei , for conditional sampling, please use `order=2`. Moreover, could you please give me more details? e.g., can `order=1` work? (which is equivalent to DDIM); what is your guidance...

@jianghuyihei I think the bug is not related to the solver, because `order=1` is DDIM. How do you train your conditional model? Maybe you should check the code of control...

Hi all, just see this cool PR! Thank you for the effort! The single-step sde-dpm++ may be a bit tricky and I need to carefully check this PR. Please give...

Sorry for the delay. will check it soon
