Selecting different samplers? #24

Open jmiskovic opened 2 years ago

jmiskovic commented 2 years ago

Some of SD interfaces expose the ability to select the sampler. In particular, the k_euler_a is known to produce good results with smaller number of iterations, which would be fantastic for CPU version.

Where does this framework select the sampler implementation? Could it be exposed in the shell arguments?

@jmiskovic no, we do not provide functionality to select different samplers

I found that DDIM is also good for fast results (3~5 iterations), though you can't really use it as a preview because the image usually changes a lot with more iterations.

I added support for DDIM in my fork: https://github.com/Drake53/stable_diffusion.openvino/commit/a56987c6bb1b8500e8662f3666d042bbdbd5296c Had to set offset to 0, otherwise it would do 1 iteration less than I asked for.
