More denoising steps usually lead to a higher quality image at the 576 | expense of slower inference. 577 | guidance_scale (`float`, *optional*, defaults to 7.5): 578 | Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598). 579 | `guidance_scale` is defined as `w` of equation 2. of [Imagen 580 | Paper](https://arxiv.org/pdf/2205.11487.pdf).

Only applies to 590 | [`schedulers.DDIMScheduler`], will be ignored for others. 591 | generator (`torch.Generator`, *optional*): 592 | One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) 593 | to make generation deterministic. 594 | latents (`torch.FloatTensor`, *optional*): 595 | Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image 596 | generation. Can be used to tweak the same generation with different prompts. If not provided, a latents 597 | tensor will ge generated by sampling using the supplied random `generator`. 598 | output_type (`str`, *optional*, defaults to `"pil"`): 599 | The output format of the generate image. Choose between 600 | [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. 601 | return_dict (`bool`, *optional*, defaults to `True`): 602 | Whether or not to return a [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] instead of a 603 | plain tuple. 604 | callback (`Callable`, *optional*): 605 | A function that will be called every `callback_steps` steps during inference. The function will be 606 | called with the following arguments: `callback(step: int, timestep: int, latents: torch.FloatTensor)`. 607 | callback_steps (`int`, *optional*, defaults to 1): 608 | The frequency at which the `callback` function will be called. If not specified, the callback will be 609 | called at every step. 610 | Examples: 611 | Returns: 612 | [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] or `tuple`: 613 | [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] if `return_dict` is True, otherwise a `tuple. 614 | When returning a tuple, the first element is a list with the generated images, and the second element is a 615 | list of `bool`s denoting whether the corresponding generated image likely represents "not-safe-for-work" 616 | (nsfw) content, according to the `safety_checker`. 617 | """ 618 | # 0.
