Ejemplo

from diffusers_load_pipeline import diffusers_load_pipeline
from diffusers_set_scheduler import diffusers_set_scheduler
from model_ref import ModelRef

model = ModelRef(name="sd-turbo", model_type="sd15", path="/path/to/model")
pipe = diffusers_load_pipeline(model)
pipe = diffusers_set_scheduler(pipe, "euler_a")
# type(pipe.scheduler).__name__ == "EulerAncestralDiscreteScheduler"

Mapping de samplers

sampler	clase diffusers	kwargs extra
euler	EulerDiscreteScheduler	—
euler_a	EulerAncestralDiscreteScheduler	—
dpm++2m	DPMSolverMultistepScheduler	algorithm_type="dpmsolver++"
dpm++2m_v2	DPMSolverMultistepScheduler	algorithm_type="dpmsolver++", solver_order=2
heun	HeunDiscreteScheduler	—

lcm	LCMScheduler	—

Notas

Usa SchedulerCls.from_config(pipe.scheduler.config, **extra_kwargs) para heredar beta_start, beta_end, clip_sample, etc. del modelo base.

Import lazy de diffusers — ImportError descriptivo si no instalado.
