sd_sampler_sigmas: Sigma schedule for a sampler (low-level)

In sd2R: Stable Diffusion Image Generation

Sigma schedule for a sampler (low-level)

Description

Returns the sigma schedule that sd_sample_stepwise iterates over, for a given scheduler / step count / generation size.

Usage

sd_sampler_sigmas(
  ctx,
  scheduler = SCHEDULER$DISCRETE,
  sample_steps = 20L,
  width = 512L,
  height = 512L,
  sample_method = SAMPLE_METHOD$EULER
)

Arguments

ctx	SD context from sd_ctx
scheduler	Scheduler (name or SCHEDULER value)
sample_steps	Number of steps
width, height	Generation size in PIXELS (same as passed to generation)
sample_method	Sampling method (name or SAMPLE_METHOD value); only used to pick a default scheduler when scheduler is a default.

Value

Numeric vector of length sample_steps + 1; the last value is 0.
