If `"auto"` is passed, the + dtype is automatically derived from the model's weights. + force_download (`bool`, *optional*, defaults to `False`): + Whether or not to force the (re-)download of the model weights and configuration files, overriding the + cached versions if they exist. + proxies (`Dict[str, str]`, *optional*): + A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128', + 'http://hostname': 'foo.bar:4012'}`.

If you are using an older version of PyTorch, setting this + argument to `True` will raise an error. + variant (`str`, *optional*): + Load weights from a specified `variant` filename such as `"fp16"` or `"ema"`. This is ignored when + loading `from_flax`. + use_safetensors (`bool`, *optional*, defaults to `None`): + If set to `None`, the `safetensors` weights are downloaded if they're available **and** if the + `safetensors` library is installed. If set to `True`, the model is forcibly loaded from `safetensors` + weights. If set to `False`, `safetensors` weights are not loaded. + disable_mmap ('bool', *optional*, defaults to 'False'): + Whether to disable mmap when loading a Safetensors model.

ControlNet uses this input condition to generate guidance to Unet. If + the type is specified as `torch.Tensor`, it is passed to ControlNet as is. `PIL.Image.Image` can also + be accepted as an image. The dimensions of the output image defaults to `image`'s dimensions. If height + and/or width are passed, `image` is resized according to them.

If `padding_mask_crop` is not `None`, it will first find a rectangular region + with the same aspect ration of the image and contains all masked area, and then expand that area based + on `padding_mask_crop`.

This is useful when the masked area is small while + the image is large and contain information irrelevant for inpainting, such as background. + strength (`float`, *optional*, defaults to 0.9999): + Conceptually, indicates how much to transform the masked portion of the reference `image`. Must be + between 0 and 1. `image` will be used as a starting point, adding more noise to it the larger the + `strength`. The number of denoising steps depends on the amount of noise initially added. When + `strength` is 1, added noise will be maximum and the denoising process will run for the full number of + iterations specified in `num_inference_steps`.

Note that in the case of `denoising_start` being declared as an + integer, the value of `strength` will be ignored. + 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.

Consequently, the initial part of the denoising process is skipped and + it is assumed that the passed `image` is a partly denoised image. Note that when this is specified, + strength will be ignored. The `denoising_start` parameter is particularly beneficial when this pipeline + is integrated into a "Mixture of Denoisers" multi-pipeline setup, as detailed in [**Refining the Image + Output**](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/stable_diffusion_xl#refining-the-image-output). + denoising_end (`float`, *optional*): + When specified, determines the fraction (between 0.0 and 1.0) of the total denoising process to be + completed before it is intentionally prematurely terminated. As a result, the returned sample will + still retain a substantial amount of noise (ca. final 20% of timesteps still needed) and should be + denoised by a successor pipeline that has `denoising_start` set to 0.8 so that it only denoises the + final 20% of the scheduler. The denoising_end parameter should ideally be utilized when this pipeline + forms a part of a "Mixture of Denoisers" multi-pipeline setup, as elaborated in [**Refining the Image + Output**](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/stable_diffusion_xl#refining-the-image-output). + guidance_scale (`float`, *optional*, defaults to 7.5): + Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598). + `guidance_scale` is defined as `w` of equation 2. of [Imagen + Paper](https://arxiv.org/pdf/2205.11487.pdf).

There are many types of conditioning inputs (canny edge, user sketching, human pose, depth, and more) you can use to control a diffusion model. This is hugely useful because it affords you greater control over image generation, making it easier to generate specific images without experimenting with different text prompts or denoising values as much. +[ControlNet](https://huggingface.co/papers/2302.05543) is an adapter that enables controllable generation such as generating an image of a cat in a *specific pose* or following the lines in a sketch of a *specific* cat. It works by adding a smaller network of "zero convolution" layers and progressively training these to avoid disrupting with the original model. The original model parameters are frozen to avoid retraining it. - +A ControlNet is conditioned on extra visual information or "structural controls" (canny edge, depth maps, human pose, etc.) that can be combined with text prompts to generate images that are guided by the visual input. -Check out Section 3.5 of the [ControlNet](https://huggingface.co/papers/2302.05543) paper v1 for a list of ControlNet implementations on various conditioning inputs.

-## Image-to-image -For image-to-image, you'd typically pass an initial image and a prompt to the pipeline to generate a new image. With ControlNet, you can pass an additional conditioning input to guide the model. Let's condition the model with a depth map, an image which contains spatial information. This way, the ControlNet can use the depth map as a control to guide the model to generate an image that preserves spatial information. + + -You'll use the [`StableDiffusionControlNetImg2ImgPipeline`] for this task, which is different from the [`StableDiffusionControlNetPipeline`] because it allows you to pass an initial image as the starting point for the image generation process. - -Load an image and use the `depth-estimation` [`~transformers.Pipeline`] from 🤗 Transformers to extract the depth map of an image: +Generate a depth map with a depth estimation pipeline from Transformers. ```py import torch import numpy as np +from PIL import Image +from transformers import DPTImageProcessor, DPTForDepthEstimation +from diffusers import ControlNetModel, StableDiffusionXLControlNetImg2ImgPipeline, AutoencoderKL +from diffusers.utils import load_image -from transformers import pipeline -from diffusers.utils import load_image, make_image_grid -image = load_image( - "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/controlnet-img2img.jpg" -) +depth_estimator = DPTForDepthEstimation.from_pretrained("Intel/dpt-hybrid-midas").to("cuda") +feature_extractor = DPTImageProcessor.from_pretrained("Intel/dpt-hybrid-midas") -def get_depth_map(image, depth_estimator): - image = depth_estimator(image)["depth"] - image = np.array(image) - image = image[:, :, None] - image = np.concatenate([image, image, image], axis=2) - detected_map = torch.from_numpy(image).float() / 255.0 - depth_map = detected_map.permute(2, 0, 1) - return depth_map +def get_depth_map(image): + image = feature_extractor(images=image, return_tensors="pt").pixel_values.to("cuda") + with torch.no_grad(), torch.autocast("cuda"): + depth_map = depth_estimator(image).predicted_depth -depth_estimator = pipeline("depth-estimation") -depth_map = get_depth_map(image, depth_estimator).unsqueeze(0).half().to("cuda") -``` - -Next, load a ControlNet model conditioned on depth maps and pass it to the [`StableDiffusionControlNetImg2ImgPipeline`].

Furthermore, this adapter can be reused with other models finetuned from the same base model and it can be combined with other adapters like [ControlNet](../using-diffusers/controlnet). The key idea behind IP-Adapter is the *decoupled cross-attention* mechanism which adds a separate cross-attention layer just for image features instead of using the same cross-attention layer for both text and image features. This allows the model to learn more image-specific features. +[IP-Adapter](https://huggingface.co/papers/2308.06721) is a lightweight adapter designed to integrate image-based guidance with text-to-image diffusion models. The adapter uses an image encoder to extract image features that are passed to the newly added cross-attention layers in the UNet and fine-tuned. The original UNet model and the existing cross-attention layers corresponding to text features is frozen. Decoupling the cross-attention for image and text features enables more fine-grained and controllable generation. + +IP-Adapter files are typically ~100MBs because they only contain the image embeddings.

-## Configure parameters +## Model variants -There are a couple of IP-Adapter parameters that are useful to know about and can help you with your image generation tasks. These parameters can make your workflow more efficient or give you more control over image generation. +There are two variants of IP-Adapter, Plus and FaceID. The Plus variant uses patch embeddings and the ViT-H image encoder. FaceID variant uses face embeddings generated from InsightFace. -### Image embeddings - -IP-Adapter enabled pipelines provide the `ip_adapter_image_embeds` parameter to accept precomputed image embeddings.

### Instant generation -[Latent Consistency Models (LCM)](../using-diffusers/inference_with_lcm_lora) are diffusion models that can generate images in as little as 4 steps compared to other diffusion models like SDXL that typically require way more steps. This is why image generation with an LCM feels "instantaneous". IP-Adapters can be plugged into an LCM-LoRA model to instantly generate images with an image prompt. +[Latent Consistency Models (LCM)](../api/pipelines/latent_consistency_models) can generate images 4 steps or less, unlike other diffusion models which require a lot more steps, making it feel "instantaneous".

### Structural control -To control image generation to an even greater degree, you can combine IP-Adapter with a model like [ControlNet](../using-diffusers/controlnet). A ControlNet is also an adapter that can be inserted into a diffusion model to allow for conditioning on an additional control image. The control image can be depth maps, edge maps, pose estimations, and more. +For structural control, combine IP-Adapter with [ControlNet](../api/pipelines/controlnet) conditioned on depth maps, edge maps, pose estimations, and more. -Load a [`ControlNetModel`] checkpoint conditioned on depth maps, insert it into a diffusion model, and load the IP-Adapter. +The example below loads a [`ControlNetModel`] checkpoint conditioned on depth maps and combines it with a IP-Adapter. ```py -from diffusers import StableDiffusionControlNetPipeline, ControlNetModel import torch from diffusers.utils import load_image +from diffusers import StableDiffusionControlNetPipeline, ControlNetModel -controlnet_model_path = "lllyasviel/control_v11f1p_sd15_depth" -controlnet = ControlNetModel.from_pretrained(controlnet_model_path, torch_dtype=torch.float16) +controlnet = ControlNetModel.from_pretrained( + "lllyasviel/control_v11f1p_sd15_depth", + torch_dtype=torch.float16 +) pipeline = StableDiffusionControlNetPipeline.from_pretrained( - "stable-diffusion-v1-5/stable-diffusion-v1-5", controlnet=controlnet, torch_dtype=torch.float16) -pipeline.to("cuda") -pipeline.load_ip_adapter("h94/IP-Adapter", subfolder="models", weight_name="ip-adapter_sd15.bin") + "stable-diffusion-v1-5/stable-diffusion-v1-5", + controlnet=controlnet, + torch_dtype=torch.float16 +).to("cuda") +pipeline.load_ip_adapter( + "h94/IP-Adapter", + subfolder="models", + weight_name="ip-adapter_sd15.bin" +) ``` -Now load the IP-Adapter image and depth map. +Pass the depth map and IP-Adapter image to the pipeline. ```py -ip_adapter_image = load_image("https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/statue.png") -depth_map = load_image("https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/depth.png") -``` - -

-### Style & layout control +### Style and layout control -[InstantStyle](https://arxiv.org/abs/2404.02733) is a plug-and-play method on top of IP-Adapter, which disentangles style and layout from image prompt to control image generation. This way, you can generate images following only the style or layout from image prompt, with significantly improved diversity. This is achieved by only activating IP-Adapters to specific parts of the model. +For style and layout control, combine IP-Adapter with [InstantStyle](https://huggingface.co/papers/2404.02733). InstantStyle separates *style* (color, texture, overall feel) and *content* from each other.

This method works by using a special word in the prompt that the model learns to associate with the subject image. Of all the training methods, DreamBooth produces the largest file size (usually a few GBs) because it is a full checkpoint model. - -Let's load the [herge_style](https://huggingface.co/sd-dreambooth-library/herge-style) checkpoint, which is trained on just 10 images drawn by Hergé, to generate images in that style.

- -## Textual inversion - -[Textual inversion](https://textual-inversion.github.io/) is very similar to DreamBooth and it can also personalize a diffusion model to generate certain concepts (styles, objects) from just a few images.

As a result, the diffusion model weights stay the same and the training process produces a relatively tiny (a few KBs) file. - -Because textual inversion creates embeddings, it cannot be used on its own like DreamBooth and requires another model. - -```py -from diffusers import AutoPipelineForText2Image -import torch - -pipeline = AutoPipelineForText2Image.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", torch_dtype=torch.float16).to("cuda") -``` - -Now you can load the textual inversion embeddings with the [`~loaders.TextualInversionLoaderMixin.load_textual_inversion`] method and generate some images.

- -## LoRA - -[Low-Rank Adaptation (LoRA)](https://huggingface.co/papers/2106.09685) is a popular training technique because it is fast and generates smaller file sizes (a couple hundred MBs). Like the other methods in this guide, LoRA can train a model to learn new styles from just a few images. It works by inserting new weights into the diffusion model and then only the new weights are trained instead of the entire model. This makes LoRAs faster to train and easier to store. - - - -LoRA is a very general training technique that can be used with other training methods. For example, it is common to train a model with DreamBooth and LoRA. It is also increasingly common to load and merge multiple LoRAs to create new and unique images. You can learn more about it in the in-depth [Merge LoRAs](merge_loras) guide since merging is outside the scope of this loading guide. - - - -LoRAs also need to be used with another model: - -```py -from diffusers import AutoPipelineForText2Image -import torch - -pipeline = AutoPipelineForText2Image.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16).to("cuda") -``` - -Then use the [`~loaders.StableDiffusionLoraLoaderMixin.load_lora_weights`] method to load the [ostris/super-cereal-sdxl-lora](https://huggingface.co/ostris/super-cereal-sdxl-lora) weights and specify the weights filename from the repository: - -```py -pipeline.load_lora_weights("ostris/super-cereal-sdxl-lora", weight_name="cereal_box_sdxl_v1.safetensors") -prompt = "bears, pizza bites" -image = pipeline(prompt).images[0] -image -``` - -
- -
- -The [`~loaders.StableDiffusionLoraLoaderMixin.load_lora_weights`] method loads LoRA weights into both the UNet and text encoder. It is the preferred way for loading LoRAs because it can handle cases where: - -- the LoRA weights don't have separate identifiers for the UNet and text encoder -- the LoRA weights have separate identifiers for the UNet and text encoder - -To directly load (and save) a LoRA adapter at the *model-level*, use [`~loaders.PeftAdapterMixin.load_lora_adapter`], which builds and prepares the necessary model configuration for the adapter. Like [`~loaders.StableDiffusionLoraLoaderMixin.load_lora_weights`], [`~loaders.PeftAdapterMixin.load_lora_adapter`] can load LoRAs for both the UNet and text encoder. For example, if you're loading a LoRA for the UNet, [`~loaders.PeftAdapterMixin.load_lora_adapter`] ignores the keys for the text encoder. - -Use the `weight_name` parameter to specify the specific weight file and the `prefix` parameter to filter for the appropriate state dicts (`"unet"` in this case) to load. - -```py -from diffusers import AutoPipelineForText2Image -import torch - -pipeline = AutoPipelineForText2Image.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16).to("cuda") -pipeline.unet.load_lora_adapter("jbilcke-hf/sdxl-cinematic-1", weight_name="pytorch_lora_weights.safetensors", prefix="unet") - -# use cnmt in the prompt to trigger the LoRA -prompt = "A cute cnmt eating a slice of pizza, stunning color scheme, masterpiece, illustration" -image = pipeline(prompt).images[0] -image -``` - -
- -
- -Save an adapter with [`~loaders.PeftAdapterMixin.save_lora_adapter`]. - -To unload the LoRA weights, use the [`~loaders.StableDiffusionLoraLoaderMixin.unload_lora_weights`] method to discard the LoRA weights and restore the model to its original weights: - -```py -pipeline.unload_lora_weights() -``` - -### Adjust LoRA weight scale - -For both [`~loaders.StableDiffusionLoraLoaderMixin.load_lora_weights`] and [`~loaders.UNet2DConditionLoadersMixin.load_attn_procs`], you can pass the `cross_attention_kwargs={"scale": 0.5}` parameter to adjust how much of the LoRA weights to use. A value of `0` is the same as only using the base model weights, and a value of `1` is equivalent to using the fully finetuned LoRA. - -For more granular control on the amount of LoRA weights used per layer, you can use [`~loaders.StableDiffusionLoraLoaderMixin.set_adapters`] and pass a dictionary specifying by how much to scale the weights in each layer by. -```python -pipe = ... # create pipeline -pipe.load_lora_weights(..., adapter_name="my_adapter") -scales = { - "text_encoder": 0.5, - "text_encoder_2": 0.5, # only usable if pipe has a 2nd text encoder - "unet": { - "down": 0.9, # all transformers in the down-part will use scale 0.9 - # "mid" # in this example "mid" is not given, therefore all transformers in the mid part will use the default scale 1.0 - "up": { - "block_0": 0.6, # all 3 transformers in the 0th block in the up-part will use scale 0.6 - "block_1": [0.4, 0.8, 1.0], # the 3 transformers in the 1st block in the up-part will use scales 0.4, 0.8 and 1.0 respectively - } - } -} -pipe.set_adapters("my_adapter", scales) -``` - -This also works with multiple adapters - see [this guide](https://huggingface.co/docs/diffusers/tutorials/using_peft_for_inference#customize-adapters-strength) for how to do it. - - - -Currently, [`~loaders.StableDiffusionLoraLoaderMixin.set_adapters`] only supports scaling attention weights. If a LoRA has other parts (e.g., resnets or down-/upsamplers), they will keep a scale of 1.0. - - - -### Hotswapping LoRA adapters - -A common use case when serving multiple adapters is to load one adapter first, generate images, load another adapter, generate more images, load another adapter, etc. This workflow normally requires calling [`~loaders.StableDiffusionLoraLoaderMixin.load_lora_weights`], [`~loaders.StableDiffusionLoraLoaderMixin.set_adapters`], and possibly [`~loaders.peft.PeftAdapterMixin.delete_adapters`] to save memory. Moreover, if the model is compiled using `torch.compile`, performing these steps requires recompilation, which takes time. - -To better support this common workflow, you can "hotswap" a LoRA adapter, to avoid accumulating memory and in some cases, recompilation. It requires an adapter to already be loaded, and the new adapter weights are swapped in-place for the existing adapter. - -Pass `hotswap=True` when loading a LoRA adapter to enable this feature. It is important to indicate the name of the existing adapter, (`default_0` is the default adapter name), to be swapped. If you loaded the first adapter with a different name, use that name instead. - -```python -pipe = ... -# load adapter 1 as normal -pipeline.load_lora_weights(file_name_adapter_1) -# generate some images with adapter 1 -... -# now hot swap the 2nd adapter -pipeline.load_lora_weights(file_name_adapter_2, hotswap=True, adapter_name="default_0") -# generate images with adapter 2 -``` - - - - -Hotswapping is not currently supported for LoRA adapters that target the text encoder. - - - -For compiled models, it is often (though not always if the second adapter targets identical LoRA ranks and scales) necessary to call [`~loaders.lora_base.LoraBaseMixin.enable_lora_hotswap`] to avoid recompilation. Use [`~loaders.lora_base.LoraBaseMixin.enable_lora_hotswap`] _before_ loading the first adapter, and `torch.compile` should be called _after_ loading the first adapter. - -```python -pipe = ... -# call this extra method -pipe.enable_lora_hotswap(target_rank=max_rank) -# now load adapter 1 -pipe.load_lora_weights(file_name_adapter_1) -# now compile the unet of the pipeline -pipe.unet = torch.compile(pipeline.unet, ...) -# generate some images with adapter 1 -... -# now hot swap adapter 2 -pipeline.load_lora_weights(file_name_adapter_2, hotswap=True, adapter_name="default_0") -# generate images with adapter 2 -``` - -The `target_rank=max_rank` argument is important for setting the maximum rank among all LoRA adapters that will be loaded. If you have one adapter with rank 8 and another with rank 16, pass `target_rank=16`. You should use a higher value if in doubt. By default, this value is 128. - -However, there can be situations where recompilation is unavoidable. For example, if the hotswapped adapter targets more layers than the initial adapter, then recompilation is triggered. Try to load the adapter that targets the most layers first. Refer to the PEFT docs on [hotswapping](https://huggingface.co/docs/peft/main/en/package_reference/hotswap#peft.utils.hotswap.hotswap_adapter) for more details about the limitations of this feature. - - - -Move your code inside the `with torch._dynamo.config.patch(error_on_recompile=True)` context manager to detect if a model was recompiled.

It works by fine-tuning a models word embeddings on 3-5 images of the concept (for example, pixel art) that is associated with a unique token (``). This allows you to use the `` token in your prompt to trigger the model to generate pixel art images. -The [`StableDiffusionPipeline`] supports textual inversion, a technique that enables a model like Stable Diffusion to learn a new concept from just a few sample images. This gives you more control over the generated images and allows you to tailor the model towards specific concepts. You can get started quickly with a collection of community created concepts in the [Stable Diffusion Conceptualizer](https://huggingface.co/spaces/sd-concepts-library/stable-diffusion-conceptualizer). - -This guide will show you how to run inference with textual inversion using a pre-learned concept from the Stable Diffusion Conceptualizer.

Our platform covers a video curation pipeline, pre-trained world foundation models, examples of post-training of pre-trained world foundation models, and video tokenizers. To help Physical AI builders solve the most critical problems of our society, we make our platform open-source and our models open-weight with permissive licenses available via

+ +[Packing Input Frame Context in Next-Frame Prediction Models for Video Generation](https://arxiv.org/abs/2504.12626) by Lvmin Zhang and Maneesh Agrawala. + +*We present a neural network structure, FramePack, to train next-frame (or next-frame-section) prediction models for video generation. The FramePack compresses input frames to make the transformer context length a fixed number regardless of the video length. As a result, we are able to process a large number of frames using video diffusion with computation bottleneck similar to image diffusion. This also makes the training video batch sizes significantly higher (batch sizes become comparable to image diffusion training). We also propose an anti-drifting sampling method that generates frames in inverted temporal order with early-established endpoints to avoid exposure bias (error accumulation over iterations). Finally, we show that existing video diffusion models can be finetuned with FramePack, and their visual quality may be improved because the next-frame prediction supports more balanced diffusion schedulers with less extreme flow shift timesteps.* + + + +Make sure to check out the Schedulers [guide](../../using-diffusers/schedulers) to learn how to explore the tradeoff between scheduler speed and quality, and see the [reuse components across pipelines](../../using-diffusers/loading#reuse-a-pipeline) section to learn how to efficiently load the same components into multiple pipelines. + + + +## Available models + +| Model name | Description | +|:---|:---| +- [`lllyasviel/FramePackI2V_HY`](https://huggingface.co/lllyasviel/FramePackI2V_HY) | Trained with the "inverted anti-drifting" strategy as described in the paper.

However, the current mainstream approach remains focused on building task-specific models, which have limited efficiency when supporting a wide range of different needs. While universal models attempt to address this limitation, they face critical challenges, including generalizable task instruction, appropriate task distributions, and unified architectural design. To tackle these challenges, we propose VisualCloze, a universal image generation framework, which supports a wide range of in-domain tasks, generalization to unseen ones, unseen unification of multiple tasks, and reverse generation. Unlike existing methods that rely on language-based task instruction, leading to task ambiguity and weak generalization, we integrate visual in-context learning, allowing models to identify tasks from visual demonstrations. Meanwhile, the inherent sparsity of visual task distributions hampers the learning of transferable knowledge across tasks. To this end, we introduce Graph200K, a graph-structured dataset that establishes various interrelated tasks, enhancing task density and transferable knowledge. Furthermore, we uncover that our unified image generation formulation shared a consistent objective with image infilling, enabling us to leverage the strong generative priors of pre-trained infilling models without modifying the architectures. The codes, dataset, and models are available at https://visualcloze.github.io.* + +## Inference + +### Model loading + +VisualCloze is a two-stage cascade pipeline, containing `VisualClozeGenerationPipeline` and `VisualClozeUpsamplingPipeline`. +- In `VisualClozeGenerationPipeline`, each image is downsampled before concatenating images into a grid layout, avoiding excessively high resolutions. VisualCloze releases two models suitable for diffusers, i.e., [VisualClozePipeline-384](https://huggingface.co/VisualCloze/VisualClozePipeline-384) and [VisualClozePipeline-512](https://huggingface.co/VisualCloze/VisualClozePipeline-384), which downsample images to resolutions of 384 and 512, respectively. +- `VisualClozeUpsamplingPipeline` uses [SDEdit](https://arxiv.org/abs/2108.01073) to enable high-resolution image synthesis. + +The `VisualClozePipeline` integrates both stages to support convenient end-to-end sampling, while also allowing users to utilize each pipeline independently as needed. + +### Input Specifications + +#### Task and Content Prompts +- Task prompt: Required to describe the generation task intention +- Content prompt: Optional description or caption of the target image +- When content prompt is not needed, pass `None` +- For batch inference, pass `List[str|None]` + +#### Image Input Format +- Format: `List[List[Image|None]]` +- Structure: + - All rows except the last represent in-context examples + - Last row represents the current query (target image set to `None`) +- For batch inference, pass `List[List[List[Image|None]]]` + +#### Resolution Control +- Default behavior: + - Initial generation in the first stage: area of ${pipe.resolution}^2$ + - Upsampling in the second stage: 3x factor +- Custom resolution: Adjust using `upsampling_height` and `upsampling_width` parameters + +### Examples + +For comprehensive examples covering a wide range of tasks, please refer to the [Online Demo](https://huggingface.co/spaces/VisualCloze/VisualCloze) and [GitHub Repository](https://github.com/lzyhha/VisualCloze).

When applying group offloading with quantization on image generation models at typical resolutions (1024x1024, for example), it is usually not possible to *fully* overlap weight transfers if the compute kernel finishes faster, making it communication bound between CPU/GPU (due to device synchronizations). + + + ## Layerwise casting Layerwise casting stores weights in a smaller data format (for example, `torch.float8_e4m3fn` and `torch.float8_e5m2`) to use less memory and upcasts those weights to a higher precision like `torch.float16` or `torch.bfloat16` for computation. Certain layers (normalization and modulation related weights) are skipped because storing them in fp8 can degrade generation quality.

AudioLDM 2 takes a text prompt as input and predicts the corresponding audio. It can generate text-conditional sound effects, human speech and music. Inspired by [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/overview), AudioLDM 2 is a text-to-audio _latent diffusion model (LDM)_ that learns continuous audio representations from text embeddings. Two text encoder models are used to compute the text embeddings from a prompt input: the text-branch of [CLAP](https://huggingface.co/docs/transformers/main/en/model_doc/clap) and the encoder of [Flan-T5](https://huggingface.co/docs/transformers/main/en/model_doc/flan-t5).

A [GPT2](https://huggingface.co/docs/transformers/main/en/model_doc/gpt2) _language model (LM)_ is used to auto-regressively predict eight new embedding vectors, conditional on the projected CLAP and Flan-T5 embeddings. The generated embedding vectors and Flan-T5 text embeddings are used as cross-attention conditioning in the LDM.

The FramePack compresses input frames to make the transformer context length a fixed number regardless of the video length. As a result, we are able to process a large number of frames using video diffusion with computation bottleneck similar to image diffusion. This also makes the training video batch sizes significantly higher (batch sizes become comparable to image diffusion training). We also propose an anti-drifting sampling method that generates frames in inverted temporal order with early-established endpoints to avoid exposure bias (error accumulation over iterations). Finally, we show that existing video diffusion models can be finetuned with FramePack, and their visual quality may be improved because the next-frame prediction supports more balanced diffusion schedulers with less extreme flow shift timesteps.* diff --git a/docs/source/en/api/pipelines/hunyuandit.md b/docs/source/en/api/pipelines/hunyuandit.md index d593259a09..9260206f4f 100644 --- a/docs/source/en/api/pipelines/hunyuandit.md +++ b/docs/source/en/api/pipelines/hunyuandit.md @@ -13,7 +13,7 @@ specific language governing permissions and limitations under the License. # Hunyuan-DiT ![chinese elements understanding](https://github.com/gnobitab/diffusers-hunyuan/assets/1157982/39b99036-c3cb-4f16-bb1a-40ec25eda573) -[Hunyuan-DiT : A Powerful Multi-Resolution Diffusion Transformer with Fine-Grained Chinese Understanding](https://arxiv.org/abs/2405.08748) from Tencent Hunyuan. +[Hunyuan-DiT : A Powerful Multi-Resolution Diffusion Transformer with Fine-Grained Chinese Understanding](https://huggingface.co/papers/2405.08748) from Tencent Hunyuan.

Latte first extracts spatio-temporal tokens from input videos and then adopts a series of Transformer blocks to model video distribution in the latent space. In order to model a substantial number of tokens extracted from videos, four efficient variants are introduced from the perspective of decomposing the spatial and temporal dimensions of input videos. To improve the quality of generated videos, we determine the best practices of Latte through rigorous experimental analysis, including video clip patch embedding, model variants, timestep-class information injection, temporal positional embedding, and learning strategies. Our comprehensive evaluation demonstrates that Latte achieves state-of-the-art performance across four standard video generation datasets, i.e., FaceForensics, SkyTimelapse, UCF101, and Taichi-HD. In addition, we extend Latte to text-to-video generation (T2V) task, where Latte achieves comparable results compared to recent T2V models. We strongly believe that Latte provides valuable insights for future research on incorporating Transformers into diffusion models for video generation.* -**Highlights**: Latte is a latent diffusion transformer proposed as a backbone for modeling different modalities (trained for text-to-video generation here).

We introduce LDM3D-VR, a suite of diffusion models targeting virtual reality development that includes LDM3D-pano and LDM3D-SR. These models enable the generation of panoramic RGBD based on textual prompts and the upscaling of low-resolution inputs to high-resolution RGBD, respectively.

However, controlling these models to ensure consistent style remains challenging, with existing methods necessitating fine-tuning and manual intervention to disentangle content and style. In this paper, we introduce StyleAligned, a novel technique designed to establish style alignment among a series of generated images. By employing minimal `attention sharing' during the diffusion process, our method maintains style consistency across images within T2I models. This approach allows for the creation of style-consistent images using a reference style through a straightforward inversion operation. Our method's evaluation across diverse styles and text prompts demonstrates high-quality synthesis and fidelity, underscoring its efficacy in achieving consistent style across various inputs. @@ -4729,7 +4729,7 @@ image = pipe( ### UFOGen Scheduler -[UFOGen](https://arxiv.org/abs/2311.09257) is a generative model designed for fast one-step text-to-image generation, trained via adversarial training starting from an initial pretrained diffusion model such as Stable Diffusion. `scheduling_ufogen.py` implements a onestep and multistep sampling algorithm for UFOGen models compatible with pipelines like `StableDiffusionPipeline`.

- -## torch.compile - -PyTorch 2 includes `torch.compile` which uses fast and optimized kernels. In Diffusers, the UNet and VAE are usually compiled because these are the most compute-intensive modules. First, configure a few compiler flags (refer to the [full list](https://github.com/pytorch/pytorch/blob/main/torch/_inductor/config.py) for more options): - -```python -from diffusers import StableDiffusionXLPipeline -import torch - -torch._inductor.config.conv_1x1_as_mm = True -torch._inductor.config.coordinate_descent_tuning = True -torch._inductor.config.epilogue_fusion = False -torch._inductor.config.coordinate_descent_check_all_directions = True -``` - -It is also important to change the UNet and VAE's memory layout to "channels_last" when compiling them to ensure maximum speed. - -```python -pipe.unet.to(memory_format=torch.channels_last) -pipe.vae.to(memory_format=torch.channels_last) -``` - -Now compile and perform inference: - -```python -# Compile the UNet and VAE. -pipe.unet = torch.compile(pipe.unet, mode="max-autotune", fullgraph=True) -pipe.vae.decode = torch.compile(pipe.vae.decode, mode="max-autotune", fullgraph=True) - -prompt = "Astronaut in a jungle, cold color palette, muted colors, detailed, 8k" - -# First call to `pipe` is slow, subsequent ones are faster. -image = pipe(prompt, num_inference_steps=30).images[0] -``` - -`torch.compile` offers different backends and modes. For maximum inference speed, use "max-autotune" for the inductor backend. “max-autotune” uses CUDA graphs and optimizes the compilation graph specifically for latency. CUDA graphs greatly reduces the overhead of launching GPU operations by using a mechanism to launch multiple GPU operations through a single CPU operation. - -Using SDPA attention and compiling both the UNet and VAE cuts the latency from 3.31 seconds to 2.54 seconds. - -
- -
- -> [!TIP] -> From PyTorch 2.3.1, you can control the caching behavior of `torch.compile()`. This is particularly beneficial for compilation modes like `"max-autotune"` which performs a grid-search over several compilation flags to find the optimal configuration. Learn more in the [Compile Time Caching in torch.compile](https://pytorch.org/tutorials/recipes/torch_compile_caching_tutorial.html) tutorial. - -### Prevent graph breaks - -Specifying `fullgraph=True` ensures there are no graph breaks in the underlying model to take full advantage of `torch.compile` without any performance degradation. For the UNet and VAE, this means changing how you access the return variables. - -```diff -- latents = unet( -- latents, timestep=timestep, encoder_hidden_states=prompt_embeds --).sample - -+ latents = unet( -+ latents, timestep=timestep, encoder_hidden_states=prompt_embeds, return_dict=False -+)[0] -``` - -### Remove GPU sync after compilation - -During the iterative reverse diffusion process, the `step()` function is [called](https://github.com/huggingface/diffusers/blob/1d686bac8146037e97f3fd8c56e4063230f71751/src/diffusers/pipelines/stable_diffusion_xl/pipeline_stable_diffusion_xl.py#L1228) on the scheduler each time after the denoiser predicts the less noisy latent embeddings. Inside `step()`, the `sigmas` variable is [indexed](https://github.com/huggingface/diffusers/blob/1d686bac8146037e97f3fd8c56e4063230f71751/src/diffusers/schedulers/scheduling_euler_discrete.py#L476) which when placed on the GPU, causes a communication sync between the CPU and GPU. This introduces latency and it becomes more evident when the denoiser has already been compiled. - -But if the `sigmas` array always [stays on the CPU](https://github.com/huggingface/diffusers/blob/35a969d297cba69110d175ee79c59312b9f49e1e/src/diffusers/schedulers/scheduling_euler_discrete.py#L240), the CPU and GPU sync doesn’t occur and you don't get any latency. In general, any CPU and GPU communication sync should be none or be kept to a bare minimum because it can impact inference latency. - -## Combine the attention block's projection matrices - -The UNet and VAE in SDXL use Transformer-like blocks which consists of attention blocks and feed-forward blocks. - -In an attention block, the input is projected into three sub-spaces using three different projection matrices – Q, K, and V. These projections are performed separately on the input. But we can horizontally combine the projection matrices into a single matrix and perform the projection in one step. This increases the size of the matrix multiplications of the input projections and improves the impact of quantization. - -You can combine the projection matrices with just a single line of code: - -```python -pipe.fuse_qkv_projections() -``` - -This provides a minor improvement from 2.54 seconds to 2.52 seconds. - -
- -
- - - -Support for [`~StableDiffusionXLPipeline.fuse_qkv_projections`] is limited and experimental. It's not available for many non-Stable Diffusion pipelines such as [Kandinsky](../using-diffusers/kandinsky). You can refer to this [PR](https://github.com/huggingface/diffusers/pull/6179) to get an idea about how to enable this for the other pipelines. - - - -## Dynamic quantization - -You can also use the ultra-lightweight PyTorch quantization library, [torchao](https://github.com/pytorch-labs/ao) (commit SHA `54bcd5a10d0abbe7b0c045052029257099f83fd9`), to apply [dynamic int8 quantization](https://pytorch.org/tutorials/recipes/recipes/dynamic_quantization.html) to the UNet and VAE. Quantization adds additional conversion overhead to the model that is hopefully made up for by faster matmuls (dynamic quantization). If the matmuls are too small, these techniques may degrade performance. - -First, configure all the compiler tags: - -```python -from diffusers import StableDiffusionXLPipeline -import torch - -# Notice the two new flags at the end. -torch._inductor.config.conv_1x1_as_mm = True -torch._inductor.config.coordinate_descent_tuning = True -torch._inductor.config.epilogue_fusion = False -torch._inductor.config.coordinate_descent_check_all_directions = True -torch._inductor.config.force_fuse_int_mm_with_mul = True -torch._inductor.config.use_mixed_mm = True -``` - -Certain linear layers in the UNet and VAE don’t benefit from dynamic int8 quantization.

However, users may want to apply -quantization on-the-fly when initializing a pipeline from a pre-trained and non-quantized checkpoint.

Typically, you should quantize the most compute intensive components like the transformer. The text encoder is another component to consider quantizing if a pipeline has more than one such as [`FluxPipeline`]. The example below quantizes the T5 text encoder in [`FluxPipeline`] while keeping the CLIP model intact. ```py import torch from diffusers import DiffusionPipeline -from diffusers.quantizers.quantization_config import QuantoConfig from diffusers.quantizers import PipelineQuantizationConfig -from transformers import BitsAndBytesConfig pipeline_quant_config = PipelineQuantizationConfig( - quant_mapping={ - "transformer": QuantoConfig(weights_dtype="int8"), - "text_encoder_2": BitsAndBytesConfig( - load_in_4bit=True, compute_dtype=torch.bfloat16 - ), - } + quant_backend="bitsandbytes_4bit", + quant_kwargs={"load_in_4bit": True, "bnb_4bit_quant_type": "nf4", "bnb_4bit_compute_dtype": torch.bfloat16}, + components_to_quantize=["transformer", "text_encoder_2"], ) ``` -Then pass it to [`~DiffusionPipeline.from_pretrained`] and run inference: +Pass the `pipeline_quant_config` to [`~DiffusionPipeline.from_pretrained`] to quantize the pipeline. ```py pipe = DiffusionPipeline.from_pretrained( @@ -77,52 +56,77 @@ pipe = DiffusionPipeline.from_pretrained( image = pipe("photo of a cute dog").images[0] ``` -This method allows for more granular control over the quantization specifications of individual -model-level components of a pipeline.

SDPA is enabled by default if you're using PyTorch 2.0 and the latest version of 🤗 Diffusers, so you don't need to add anything to your code. - -However, if you want to explicitly enable it, you can set a [`DiffusionPipeline`] to use [`~models.attention_processor.AttnProcessor2_0`]: - -```diff - import torch - from diffusers import DiffusionPipeline -+ from diffusers.models.attention_processor import AttnProcessor2_0 - - pipe = DiffusionPipeline.from_pretrained("stable-diffusion-v1-5/stable-diffusion-v1-5", torch_dtype=torch.float16, use_safetensors=True).to("cuda") -+ pipe.unet.set_attn_processor(AttnProcessor2_0()) - - prompt = "a photo of an astronaut riding a horse on mars" - image = pipe(prompt).images[0] -``` - -SDPA should be as fast and memory efficient as `xFormers`; check the [benchmark](#benchmark) for more details. - -In some cases - such as making the pipeline more deterministic or converting it to other formats - it may be helpful to use the vanilla attention processor, [`~models.attention_processor.AttnProcessor`].

Models are often composed of multiple repeated blocks. [Regional compilation](https://pytorch.org/tutorials/recipes/regional_compilation.html) compiles the repeated block first (a transformer encoder block, for example), so that the Torch compiler would re-use its cached/optimized generated code for the other blocks, reducing (often massively) the cold start compilation time observed on the first inference call. - -Enabling regional compilation might require simple yet intrusive changes to the -modeling code. However, 🤗 Accelerate provides a utility [`compile_regions()`](https://huggingface.co/docs/accelerate/main/en/usage_guides/compilation#how-to-use-regional-compilation) which automatically compiles -the repeated blocks of the provided `nn.Module` sequentially, and the rest of the model separately.
