r""" |
|
The call function to the pipeline for generation. |
|
|
|
Args: |
|
prompt (`str` or `List[str]`): |
|
The prompt or prompts to guide image generation. If not defined, you need to pass `prompt_embeds`. |
|
height (`int`): |
|
The height in pixels of the generated image. |
|
width (`int`): |
|
The width in pixels of the generated image. |
|
video_length (`int`): |
|
The number of frames in the generated video. |
|
num_inference_steps (`int`, *optional*, defaults to 50): |
|
The number of denoising steps. More denoising steps usually lead to a higher quality image at the |
|
expense of slower inference. |
|
timesteps (`List[int]`, *optional*): |
|
Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument |
|
in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is |
|
passed will be used. Must be in descending order. |
|
sigmas (`List[float]`, *optional*): |
|
Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in |
|
their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed |
|
will be used. |
|
guidance_scale (`float`, *optional*, defaults to 7.5): |
|
A higher guidance scale value encourages the model to generate images closely linked to the text |
|
`prompt` at the expense of lower image quality. Guidance scale is enabled when `guidance_scale > 1`. |
|
negative_prompt (`str` or `List[str]`, *optional*): |
|
The prompt or prompts to guide what to not include in image generation. If not defined, you need to |
|
pass `negative_prompt_embeds` instead. Ignored when not using guidance (`guidance_scale < 1`). |
|
num_videos_per_prompt (`int`, *optional*, defaults to 1): |
|
The number of images to generate per prompt. |
|
eta (`float`, *optional*, defaults to 0.0): |
|
Corresponds to parameter eta (η) from the [DDIM](https://arxiv.org/abs/2010.02502) paper. Only applies |
|
to the [`~schedulers.DDIMScheduler`], and is ignored in other schedulers. |
|
generator (`torch.Generator` or `List[torch.Generator]`, *optional*): |
|
A [`torch.Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) to make |
|
generation deterministic. |
|
latents (`torch.Tensor`, *optional*): |
|
Pre-generated noisy latents sampled from a Gaussian distribution, to be used as inputs for image |
|
generation. Can be used to tweak the same generation with different prompts. If not provided, a latents |
|
tensor is generated by sampling using the supplied random `generator`. |
|
prompt_embeds (`torch.Tensor`, *optional*): |
|
Pre-generated text embeddings. Can be used to easily tweak text inputs (prompt weighting). If not |
|
provided, text embeddings are generated from the `prompt` input argument. |
|
negative_prompt_embeds (`torch.Tensor`, *optional*): |
|
Pre-generated negative text embeddings. Can be used to easily tweak text inputs (prompt weighting). If |
|
not provided, `negative_prompt_embeds` are generated from the `negative_prompt` input argument. |
|
|
|
output_type (`str`, *optional*, defaults to `"pil"`): |
|
The output format of the generated image. Choose between `PIL.Image` or `np.array`. |
|
return_dict (`bool`, *optional*, defaults to `True`): |
|
Whether or not to return a [`MatrixGameVideoPipelineOutput`] instead of a |
|
plain tuple. |
|
cross_attention_kwargs (`dict`, *optional*): |
|
A kwargs dictionary that if specified is passed along to the [`AttentionProcessor`] as defined in |
|
[`self.processor`](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py). |
|
guidance_rescale (`float`, *optional*, defaults to 0.0): |
|
Guidance rescale factor from [Common Diffusion Noise Schedules and Sample Steps are |
|
Flawed](https://arxiv.org/pdf/2305.08891.pdf). Guidance rescale factor should fix overexposure when |
|
using zero terminal SNR. |
|
clip_skip (`int`, *optional*): |
|
Number of layers to be skipped from CLIP while computing the prompt embeddings. A value of 1 means that |
|
the output of the pre-final layer will be used for computing the prompt embeddings. |
|
callback_on_step_end (`Callable`, `PipelineCallback`, `MultiPipelineCallbacks`, *optional*): |
|
A function or a subclass of `PipelineCallback` or `MultiPipelineCallbacks` that is called at the end of |
|
each denoising step during the inference. with the following arguments: `callback_on_step_end(self: |
|
DiffusionPipeline, step: int, timestep: int, callback_kwargs: Dict)`. `callback_kwargs` will include a |
|
list of all tensors as specified by `callback_on_step_end_tensor_inputs`. |
|
callback_on_step_end_tensor_inputs (`List`, *optional*): |
|
The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list |
|
will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the |
|
`._callback_tensor_inputs` attribute of your pipeline class. |
|
|
|
Examples: |
|
|
|
Returns: |
|
[`~MatrixGameVideoPipelineOutput`] or `tuple`: |
|
If `return_dict` is `True`, [`MatrixGameVideoPipelineOutput`] is returned, |
|
otherwise a `tuple` is returned where the first element is a list with the generated images and the |
|
second element is a list of `bool`s indicating whether the corresponding generated image contains |
|
"not-safe-for-work" (nsfw) content. |
