What happened

When using the starter model dreamshaper 8 (or dreamshaper 8 inpainting) and some schedulers, generation fails during denoising.

Only these schedulers trigger the error:

• DPM++ 2M
• DPM++ 2M Karras
• DPM++ 2S
• DPM++ 2S Karras

The starter models tab installs a diffusers version of the affected models. When using the checkpoint version of this model, there is no error.

What you expected to happen

All the schedulers work.

I'd guess it's picking up algorithm-type 'deis' from the default scheduler for the model which is DEISMultistepScheduler, and using that in the scheduler config for the DPM schedulers.
DEISMultistepScheduler however doesn't have a final_sigmas_type parameter so it's using the default 'zero' value for final_sigmas_type from the DPM schedulers which is not compatible with the deis algorithm type.

It's probably going to need a check for this in the code which picks other f the values to change (algorithm type would seem most sensible to me, so DPM using its default value) unless the InvokeAI team give us a way of changing the scheduler parameters.
