[Feature Request] Community Euler Samplers

[iwr-redmond]

Despite the arrival of FLUX, I reckon SD15 is still going strong. As you have recently implemented some extra samplers in the dev version, would it be possible to add the Extra Euler Samplers? They are often recommended for improving hand generation in SD15 checkpoints.

The process should be pretty similar to the work already undertaken.

Thanks for putting in the Max and Negative samplers for testing. Looking at the code for the other community Euler samplers, it seems these require greater integration with the k-diffusion package.

Diffusers has a wrapper for k-diffusion that makes this plausible. The key part is at lines 136-147, which searches the k_diffusion/samplers.py file.

Perhaps the remaining extra samplers could be put together in a single file and then polled in a similar manner? (As an aside, this might also provide an opportunity to offer the original k-diffusion samplers where they are of higher quality to the diffusers re-implementations.)

Totally makes sense
For now, though, I’m sticking with the Diffusers schedulers since they’re already pretty built-in with what I’m doing. However, leveraging the k-diffusion wrapper is definitely a good idea for future enhancements
