Struct DDIMConfig 

pub struct DDIMConfig {
    pub num_train_timesteps: usize,
    pub beta_start: f64,
    pub beta_end: f64,
    pub beta_schedule: BetaSchedule,
    pub clip_sample: bool,
    pub set_alpha_to_one: bool,
    pub prediction_type: PredictionType,
    pub timestep_spacing: TimestepSpacing,
    pub steps_offset: usize,
}

DDIMScheduler configuration (the subset that affects forward math).

Fields

num_train_timesteps: usize

num_train_timesteps — SD-1.5: 1000.

beta_start: f64

beta_start — SD-1.5: 0.00085.

beta_end: f64

beta_end — SD-1.5: 0.012.

beta_schedule: BetaSchedule

beta_schedule — SD-1.5: ScaledLinear.

clip_sample: bool

clip_sample — SD-1.5: false (no clipping of predicted x0).

set_alpha_to_one: bool

set_alpha_to_one — SD-1.5: false. When false, the final-step alpha_prev is alphas_cumprod[0] (matches diffusers).

prediction_type: PredictionType

prediction_type — SD-1.5: “epsilon” (the UNet predicts the noise). Only "epsilon" is implemented; anything else returns an error at set_timesteps time.

timestep_spacing: TimestepSpacing

timestep_spacing — SD-1.5: Leading.

steps_offset: usize

steps_offset — SD-1.5: 1 (diffusers adds this offset on the leading path so the first inference step is step_ratio rather than 0; consumed inside DDIMScheduler::set_timesteps).

Implementations

impl DDIMConfig

pub fn sd_v1_5() -> Self

SD-1.5 defaults (alias for Default::default).

Trait Implementations

impl Clone for DDIMConfig

fn clone(&self) -> DDIMConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DDIMConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DDIMConfig

fn default() -> Self

Returns the “default value” for a type.
