496
+ The call function to the pipeline for generation.
497
+
498
+ Args:
499
+ prompt (`str` or `List[str]`, *optional*):
500
+ The prompt or prompts to guide image generation. If not defined, you need to pass `prompt_embeds`.
501
+ height (`int`, *optional*, defaults to `self.unet.config.sample_size * self.vae_scale_factor`):
502
+ The height in pixels of the generated image.
503
+ width (`int`, *optional*, defaults to `self.unet.config.sample_size * self.vae_scale_factor`):
504
+ The width in pixels of the generated image.
505
+ num_inference_steps (`int`, *optional*, defaults to 50):
506
+ The number of denoising steps. More denoising steps usually lead to a higher quality image at the
507
+ expense of slower inference.
508
+ guidance_scale (`float`, *optional*, defaults to 7.5):
509
+ A higher guidance scale value encourages the model to generate images closely linked to the text
510
+ `prompt` at the expense of lower image quality. Guidance scale is enabled when `guidance_scale > 1`.
511
+ interactdiffusion_subject_phrases (`List[str]`):
512
+ The phrases to guide what to include in each of the subject defined by the corresponding
513
+ `interactdiffusion_subject_boxes`. There should only be one phrase per subject bounding box.
514
+ interactdiffusion_subject_boxes (`List[List[float]]`):
515
+ The bounding boxes that identify rectangular regions of the image that are going to be filled with the
516
+ subject described by the corresponding `interactdiffusion_subject_phrases`. Each rectangular box is
517
+ defined as a `List[float]` of 4 elements `[xmin, ymin, xmax, ymax]` where each value is between [0,1].
518
+ interactdiffusion_object_phrases (`List[str]`):
519
+ The phrases to guide what to include in each of the object defined by the corresponding
520
+ `interactdiffusion_object_boxes`. There should only be one phrase per object bounding box.
521
+ interactdiffusion_object_boxes (`List[List[float]]`):
522
+ The bounding boxes that identify rectangular regions of the image that are going to be filled with the
523
+ object described by the corresponding `interactdiffusion_object_phrases`. Each rectangular box is
524
+ defined as a `List[float]` of 4 elements `[xmin, ymin, xmax, ymax]` where each value is between [0,1].
525
+ interactdiffusion_action_phrases (`List[str]`):
526
+ The phrases to guide what to include in each of the interaction defined between subject and object bounding boxes.
527
+ There should only be one phrase per subject-object pair.
528
+ interactdiffusion_scheduled_sampling_beta (`float`, defaults to 1.0):
529
+ Scheduled Sampling factor from [GLIGEN: Open-Set Grounded Text-to-Image
530
+ Generation](https://arxiv.org/pdf/2301.07093.pdf). Scheduled Sampling factor is only varied for
531
+ scheduled sampling during inference for improved quality and controllability.
532
+ negative_prompt (`str` or `List[str]`, *optional*):
533
+ The prompt or prompts to guide what to not include in image generation. If not defined, you need to
534
+ pass `negative_prompt_embeds` instead. Ignored when not using guidance (`guidance_scale < 1`).
535
+ num_images_per_prompt (`int`, *optional*, defaults to 1):
536
+ The number of images to generate per prompt.
537
+ eta (`float`, *optional*, defaults to 0.0):
538
+ Corresponds to parameter eta (η) from the [DDIM](https://arxiv.org/abs/2010.02502) paper. Only applies
539
+ to the [`~schedulers.DDIMScheduler`], and is ignored in other schedulers.
540
+ generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
541
+ A [`torch.Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) to make
542
+ generation deterministic.
543
+ latents (`torch.FloatTensor`, *optional*):
544
+ Pre-generated noisy latents sampled from a Gaussian distribution, to be used as inputs for image
545
+ generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
546
+ tensor is generated by sampling using the supplied random `generator`.
547
+ prompt_embeds (`torch.FloatTensor`, *optional*):
548
+ Pre-generated text embeddings. Can be used to easily tweak text inputs (prompt weighting). If not
549
+ provided, text embeddings are generated from the `prompt` input argument.
550
+ negative_prompt_embeds (`torch.FloatTensor`, *optional*):
551
+ Pre-generated negative text embeddings. Can be used to easily tweak text inputs (prompt weighting). If
552
+ not provided, `negative_prompt_embeds` are generated from the `negative_prompt` input argument.
553
+ output_type (`str`, *optional*, defaults to `"pil"`):
554
+ The output format of the generated image. Choose between `PIL.Image` or `np.array`.
555
+ return_dict (`bool`, *optional*, defaults to `True`):
556
+ Whether or not to return a [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] instead of a
557
+ plain tuple.
558
+ callback (`Callable`, *optional*):
559
+ A function that calls every `callback_steps` steps during inference. The function is called with the
560
+ following arguments: `callback(step: int, timestep: int, latents: torch.FloatTensor)`.
561
+ callback_steps (`int`, *optional*, defaults to 1):
562
+ The frequency at which the `callback` function is called. If not specified, the callback is called at
563
+ every step.
564
+ cross_attention_kwargs (`dict`, *optional*):
565
+ A kwargs dictionary that if specified is passed along to the [`AttentionProcessor`] as defined in
566
+ [`self.processor`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
567
+ guidance_rescale (`float`, *optional*, defaults to 0.0):
568
+ Guidance rescale factor from [Common Diffusion Noise Schedules and Sample Steps are
569
+ Flawed](https://arxiv.org/pdf/2305.08891.pdf). Guidance rescale factor should fix overexposure when
570
+ using zero terminal SNR.
571
+ clip_skip (`int`, *optional*):
572
+ Number of layers to be skipped from CLIP while computing the prompt embeddings. A value of 1 means that
573
+ the output of the pre-final layer will be used for computing the prompt embeddings.
574
+ Examples:
575
+
576
+ Returns:
577
+ [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] or `tuple`:
578
+ If `return_dict` is `True`, [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] is returned,
579
+ otherwise a `tuple` is returned where the first element is a list with the generated images and the
580
+ second element is a list of `bool`s indicating whether the corresponding generated image contains
581
+ "not-safe-for-work" (nsfw) content.
