VQModel The VQ-VAE model was introduced in Neural Discrete Representation Learning by Aaron van den Oord, Oriol Vinyals and Koray Kavukcuoglu. The model is used in πŸ€— Diffusers to decode latent representations into images. Unlike AutoencoderKL, the VQModel works in a quantized latent space. The abstract from the paper ...
Tuple of downsample block types. up_block_types (Tuple[str], optional, defaults to ("UpDecoderBlock2D",)) β€”
Tuple of upsample block types. block_out_channels (Tuple[int], optional, defaults to (64,)) β€”
Tuple of block output channels. layers_per_block (int, optional, defaults to 1) β€” Number of layers per block. act_fn (str, optional, defaults to "silu") β€” The activation function to use. latent_channels (int, optional, defaults to 3) β€” Number of channels in the latent space. sample_size (int, optional, defaults...
The component-wise standard deviation of the trained latent space computed using the first batch of the
training set. This is used to scale the latent space to have unit variance when training the diffusion
model. The latents are scaled with the formula z = z * scaling_factor before being passed to the
diffusion model. When decoding, the latents are scaled back to the original scale with the formula: z = 1 / scaling_factor * z. For more details, refer to sections 4.3.2 and D.1 of the High-Resolution Image
Synthesis with Latent Diffusion Models paper. norm_type (str, optional, defaults to "group") β€”
Type of normalization layer to use. Can be one of "group" or "spatial". A VQ-VAE model for decoding latent representations. This model inherits from ModelMixin. Check the superclass documentation for it’s generic methods implemented
for all models (such as downloading or saving). forward < source > ( sample: FloatTensor return_dict: bool = True ) β†’ VQEncoderOutput or tuple Parameters sample (torch.FloatTensor) β€” Input sample. return_dict (bool, optional, defaults to True) β€”
Whether or not to return a models.vq_model.VQEncoderOutput instead of a plain tuple. Returns
VQEncoderOutput or tuple
If return_dict is True, a VQEncoderOutput is returned, otherwise a plain tuple
is returned.
The VQModel forward method. VQEncoderOutput class diffusers.models.vq_model.VQEncoderOutput < source > ( latents: FloatTensor ) Parameters latents (torch.FloatTensor of shape (batch_size, num_channels, height, width)) β€”
The encoded output sample from the last layer of the model. Output of VQModel encoding method.
Paint by Example Paint by Example: Exemplar-based Image Editing with Diffusion Models is by Binxin Yang, Shuyang Gu, Bo Zhang, Ting Zhang, Xuejin Chen, Xiaoyan Sun, Dong Chen, Fang Wen. The abstract from the paper is: Language-guided image editing has achieved great success recently. In this paper, for the first time, ...
Variational Auto-Encoder (VAE) model to encode and decode images to and from latent representations. image_encoder (PaintByExampleImageEncoder) β€”
Encodes the example input image. The unet is conditioned on the example image instead of a text prompt. tokenizer (CLIPTokenizer) β€”
A CLIPTokenizer to tokenize text. unet (UNet2DConditionModel) β€”
A UNet2DConditionModel to denoise the encoded image latents. scheduler (SchedulerMixin) β€”
A scheduler to be used in combination with unet to denoise the encoded image latents. Can be one of
DDIMScheduler, LMSDiscreteScheduler, or PNDMScheduler. safety_checker (StableDiffusionSafetyChecker) β€”
Classification module that estimates whether generated images could be considered offensive or harmful.
Please refer to the model card for more details
about a model’s potential harms. feature_extractor (CLIPImageProcessor) β€”
A CLIPImageProcessor to extract features from generated images; used as inputs to the safety_checker. πŸ§ͺ This is an experimental feature! Pipeline for image-guided image inpainting using Stable Diffusion. This model inherits from DiffusionPipeline. Check the superclass documentation for the generic methods
implemented for all pipelines (downloading, saving, running on a particular device, etc.). __call__ < source > ( example_image: Union image: Union mask_image: Union height: Optional = None width: Optional = None num_inference_steps: int = 50 guidance_scale: float = 5.0 negative_prompt: Union = None num_images_per_pro...
An example image to guide image generation. image (torch.FloatTensor or PIL.Image.Image or List[PIL.Image.Image]) β€”
Image or tensor representing an image batch to be inpainted (parts of the image are masked out with
mask_image and repainted according to prompt). mask_image (torch.FloatTensor or PIL.Image.Image or List[PIL.Image.Image]) β€”
Image or tensor representing an image batch to mask image. White pixels in the mask are repainted,
while black pixels are preserved. If mask_image is a PIL image, it is converted to a single channel
(luminance) before use. If it’s a tensor, it should contain one color channel (L) instead of 3, so the
expected shape would be (B, H, W, 1). height (int, optional, defaults to self.unet.config.sample_size * self.vae_scale_factor) β€”
The height in pixels of the generated image. width (int, optional, defaults to self.unet.config.sample_size * self.vae_scale_factor) β€”
The width in pixels of the generated image. num_inference_steps (int, optional, defaults to 50) β€”
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
expense of slower inference. guidance_scale (float, optional, defaults to 7.5) β€”
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) β€”
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_images_per_prompt (int, optional, defaults to 1) β€”
The number of images to generate per prompt. eta (float, optional, defaults to 0.0) β€”
Corresponds to parameter eta (Ξ·) from the DDIM paper. Only applies
to the DDIMScheduler, and is ignored in other schedulers. generator (torch.Generator or List[torch.Generator], optional) β€”
A torch.Generator to make
generation deterministic. latents (torch.FloatTensor, optional) β€”
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. output_type (str, optional, defaults to "pil") β€”
The output format of the generated image. Choose between PIL.Image or np.array. return_dict (bool, optional, defaults to True) β€”
Whether or not to return a StableDiffusionPipelineOutput instead of a
plain tuple. callback (Callable, optional) β€”
A function that calls every callback_steps steps during inference. The function is called with the
following arguments: callback(step: int, timestep: int, latents: torch.FloatTensor). callback_steps (int, optional, defaults to 1) β€”
The frequency at which the callback function is called. If not specified, the callback is called at
every step. Returns
StableDiffusionPipelineOutput or tuple
If return_dict is True, StableDiffusionPipelineOutput 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 bools indicating whether the corresponding generated image contains
β€œnot-safe-for-work” (nsfw) content.
The call function to the pipeline for generation. Example: Copied >>> import PIL

... response = requests.get(url)
... return PIL.Image.open(BytesIO(response.content)).convert("RGB")

... )
>>> example_url = "https://raw.githubusercontent.com/Fantasy-Studio/Paint-by-Example/main/examples/reference/example_1.jpg"
