Function invoked when calling the pipeline for generation.

Args:
|

-
prompt (`str` or `List[str]`, *optional*):
|
| 254 |
-
The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
|
| 255 |
-
instead.
|
| 256 |
-
height (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
|
| 257 |
-
The height in pixels of the generated image. This is set to 1024 by default for the best results.
|
| 258 |
-
width (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
|
| 259 |
-
The width in pixels of the generated image. This is set to 1024 by default for the best results.
|
| 260 |
-
num_inference_steps (`int`, *optional*, defaults to 50):
|
| 261 |
-
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
|
| 262 |
-
expense of slower inference.
|
| 263 |
-
timesteps (`List[int]`, *optional*):
|
| 264 |
-
Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument
|
| 265 |
-
in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is
|
| 266 |
-
passed will be used. Must be in descending order.
|
| 267 |
-
guidance_scale (`float`, *optional*, defaults to 5.0):
|
| 268 |
-
Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
|
| 269 |
-
`guidance_scale` is defined as `w` of equation 2. of [Imagen
|
| 270 |
-
Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
|
| 271 |
-
1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
|
| 272 |
-
usually at the expense of lower image quality.
|
| 273 |
-
negative_prompt (`str` or `List[str]`, *optional*):
|
| 274 |
-
The prompt or prompts not to guide the image generation. If not defined, one has to pass
|
| 275 |
-
`negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is
|
| 276 |
-
less than `1`).
|
| 277 |
-
num_images_per_prompt (`int`, *optional*, defaults to 1):
|
| 278 |
-
The number of images to generate per prompt.
|
| 279 |
-
generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
|
| 280 |
-
One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
|
| 281 |
-
to make generation deterministic.
|
| 282 |
-
latents (`torch.FloatTensor`, *optional*):
|
| 283 |
-
Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
|
| 284 |
-
generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
|
| 285 |
-
tensor will ge generated by sampling using the supplied random `generator`.
|
| 286 |
-
prompt_embeds (`torch.FloatTensor`, *optional*):
|
| 287 |
-
Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
|
| 288 |
-
provided, text embeddings will be generated from `prompt` input argument.
|
| 289 |
-
negative_prompt_embeds (`torch.FloatTensor`, *optional*):
|
| 290 |
-
Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
|
| 291 |
-
weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input
|
| 292 |
-
argument.
|
| 293 |
-
output_type (`str`, *optional*, defaults to `"pil"`):
|
| 294 |
-
The output format of the generate image. Choose between
|
| 295 |
-
[PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
|
| 296 |
-
return_dict (`bool`, *optional*, defaults to `True`):
|
| 297 |
-
Whether or not to return a [`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] instead
|
| 298 |
-
of a plain tuple.
|
| 299 |
-
joint_attention_kwargs (`dict`, *optional*):
|
| 300 |
-
A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
|
| 301 |
-
`self.processor` in
|
| 302 |
-
[diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
|

callback_on_step_end (`Callable`, *optional*):
|
| 304 |
-
A function that calls at the end of each denoising steps during the inference. The function is called

with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
|
| 306 |
-
callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
|
| 307 |
-
`callback_on_step_end_tensor_inputs`.
|
| 308 |
-
callback_on_step_end_tensor_inputs (`List`, *optional*):
|
| 309 |
-
The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
|
| 310 |
-
will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
|
| 311 |
-
`._callback_tensor_inputs` attribute of your pipeline class.
|
| 312 |
-
max_sequence_length (`int` defaults to 256): Maximum sequence length to use with the `prompt`.
|
| 313 |
-
|
| 314 |
-
Examples:
|
| 315 |
-
|
| 316 |
-
Returns:
|
| 317 |
-
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] or `tuple`:
|
| 318 |
-
[`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] if `return_dict` is True, otherwise a
|
| 319 |
-
`tuple`. When returning a tuple, the first element is a list with the generated images.
