      Improve docstrings and type hints in scheduling_euler_discrete.py (#12654) · 63dd6017
      David El Malih authored
      * refactor: enhance type hints and documentation in EulerDiscreteScheduler
      
      Updated type hints for function parameters and return types in the EulerDiscreteScheduler class to improve code clarity and maintainability. Enhanced docstrings for several methods to provide clearer descriptions of their functionality and expected arguments. This includes specifying Literal types for certain parameters and ensuring consistent return type annotations across the class.
      
      * refactor: enhance type hints and documentation across multiple schedulers
      
      Updated type hints and improved docstrings in various scheduler classes, including CMStochasticIterativeScheduler, CosineDPMSolverMultistepScheduler, and others. This includes specifying parameter types, return types, and providing clearer descriptions of method functionalities. Notable changes include the addition of default values in the begin_index argument and enhanced explanations for noise addition methods. These improvements aim to enhance code clarity and maintainability across the scheduling module.
      
      * refactor: update docstrings to clarify noise schedule construction
      
      Revised docstrings across multiple scheduler classes to enhance clarity regarding the construction of noise schedules. Updated references to relevant papers, ensuring accurate citations for the methodologies used. This includes changes in DEISMultistepScheduler, DPMSolverMultistepInverseScheduler, and others, improving documentation consistency and readability.

      EulerAncestral add `rescale_betas_zero_snr` (#6187) · 457abdf2
      Beinsezii authored
      
      
      * EulerAncestral add `rescale_betas_zero_snr`
      
      Uses same infinite sigma fix from EulerDiscrete. Interestingly the
      ancestral version had the opposite problem: too much contrast instead of
      too little.
      
      * UT for EulerAncestral `rescale_betas_zero_snr`
      
      * EulerAncestral upcast samples during step()
      
      It helps this scheduler too, particularly when the model is using bf16.
      
      While the noise dtype is still the model's it's automatically upcasted
      for the add so all it affects is determinism.

      Add `timestep_spacing` and `steps_offset` to schedulers (#3947) · 07c9a08e
      Pedro Cuenca authored
      
      
      * Add timestep_spacing to DDPM, LMSDiscrete, PNDM.
      
      * Remove spurious line.
      
      * More easy schedulers.
      
      * Add `linspace` to DDIM
      
      * Noise sigma for `trailing`.
      
      * Add timestep_spacing to DEISMultistepScheduler.
      
      Not sure the range is the way it was intended.
      
      * Fix: remove line used to debug.
      
      * Support timestep_spacing in DPMSolverMultistep, DPMSolverSDE, UniPC
      
      * Fix: convert to numpy.
      
      * Use sched. defaults when instantiating from_config
      
      For params not present in the original configuration.
      
      This makes it possible to switch pipeline schedulers even if they use
      different timestep_spacing (or any other param).

      * Missing args in DPMSolverMultistep
      
      * Test: default args not in config
      
      * Style
      
      * Fix scheduler name in test
      
      * Remove duplicated entries
      
      * Add test for solver_type
      
      This test currently fails in main. When switching from DEIS to UniPC,
      solver_type is "logrho" (the default value from DEIS), which gets
      translated to "bh1" by UniPC. This is different to the default value for
      UniPC: "bh2". This is where the translation happens: https://github.com/huggingface/diffusers/blob/36d22d0709dc19776e3016fb3392d0f5578b0ab2/src/diffusers/schedulers/scheduling_unipc_multistep.py#L171
      
      
      
      * UniPC: use same default for solver_type
      
      Fixes a bug when switching from UniPC from another scheduler (i.e.,
      DEIS) that uses a different solver type. The solver is now the same as
      if we had instantiated the scheduler directly.

      * Update tests/pipelines/stable_diffusion/test_stable_diffusion_pix2pix_zero.py
      
      * Default steps_offset to 0.
      
      * Add missing docstrings
      
      * Apply suggestions from code review
