is: + +*Significant advancements have been made in the field of video generation, with the open-source community contributing a wealth of research papers and tools for training high-quality models. However, despite these efforts, the available information and resources remain insufficient for achieving commercial-level performance. In this report, we open the black box and introduce Allegro, an advanced video generation model that excels in both quality and temporal consistency. We also highlight the current limitations in the field and present a comprehensive methodology for training high-performance, commercial-level video generation models, addressing key aspects such as data, model architecture, training pipeline, and evaluation. Our user study shows that Allegro surpasses existing open-source models and most commercial models, ranking just behind Hailuo and Kling.

If not defined, you need to pass `prompt_embeds`. + image (`PIL.Image.Image`): + `Image` or tensor representing an image batch to be inpainted (which parts of the image to be masked + out with `default_mask_image` and repainted according to `prompt`). + default_mask_image (`PIL.Image.Image`): + `Image` or tensor representing an image batch to mask `image`. White pixels in the mask are repainted + while black pixels are preserved. If `default_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`): + The height in pixels of the generated image. + width (`int`, *optional*, defaults to `self.unet.config.sample_size * self.vae_scale_factor`): + The width in pixels of the generated image. + strength (`float`, *optional*, defaults to 1.0): + Indicates extent to transform the reference `image`. Must be between 0 and 1. `image` is used as a + starting point and more noise is added the higher the `strength`. The number of denoising steps depends + on the amount of noise initially added. When `strength` is 1, added noise is maximum and the denoising + process runs for the full number of iterations specified in `num_inference_steps`. A value of 1 + essentially ignores `image`. + 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. This parameter is modulated by `strength`. + 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_images_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.FloatTensor`, *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.FloatTensor`, *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.FloatTensor`, *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 [`~pipelines.stable_diffusion.StableDiffusionPipelineOutput`] instead of a + plain tuple. + callback (`Callable`, *optional*): + 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): + The frequency at which the `callback` function is called. If not specified, the callback is called at + every step. + 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). + + Examples: + + ```py + >>> import PIL + >>> import requests + >>> import torch + >>> from io import BytesIO + + >>> from diffusers import AdaptiveMaskInpaintPipeline + + + >>> def download_image(url): + ... response = requests.get(url) + ... return PIL.Image.open(BytesIO(response.content)).convert("RGB") + + + >>> img_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo.png" + >>> mask_url = "https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo_mask.png" + + >>> init_image = download_image(img_url).resize((512, 512)) + >>> default_mask_image = download_image(mask_url).resize((512, 512)) + + >>> pipe = AdaptiveMaskInpaintPipeline.from_pretrained( + ...

Unlike traditional methods that rely solely on complex text prompts, IP Adapter introduces the concept of using image prompts, leveraging the idea that "an image is worth a thousand words." By decoupling cross-attention layers for text and image features, IP Adapter effectively integrates image prompts into the generation process without the need for extensive fine-tuning or large computing resources. + +## Training locally with PyTorch + +### Installing the dependencies + +Before running the scripts, make sure to install the library's training dependencies: + +**Important** + +To make sure you can successfully run the latest versions of the example scripts, we highly recommend **installing from source** and keeping the install up to date as we update the example scripts frequently and install some example-specific requirements.

If it is a numpy array or a + list of arrays, the expected shape should be `(B, H, W, C)` or `(H, W, C)` It can also accept image + latents as `image`, but if passing latents directly it is not encoded again. + strength (`float`, *optional*, defaults to 0.8): + Indicates extent to transform the reference `image`. Must be between 0 and 1. `image` is used as a + starting point and more noise is added the higher the `strength`. The number of denoising steps depends + on the amount of noise initially added. When `strength` is 1, added noise is maximum and the denoising + process runs for the full number of iterations specified in `num_inference_steps`. A value of 1 + essentially ignores `image`. + 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. + guidance_scale (`float`, *optional*, defaults to 7.0): + 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). Guidance scale is enabled by setting `guidance_scale > + 1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`, + usually at the expense of lower image quality. + negative_prompt (`str` or `List[str]`, *optional*): + The prompt or prompts not to guide the image generation. If not defined, one has to pass + `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is + less than `1`). + negative_prompt_2 (`str` or `List[str]`, *optional*): + The prompt or prompts not to guide the image generation to be sent to `tokenizer_2` and + `text_encoder_2`. If not defined, `negative_prompt` is used instead + negative_prompt_3 (`str` or `List[str]`, *optional*): + The prompt or prompts not to guide the image generation to be sent to `tokenizer_3` and + `text_encoder_3`. If not defined, `negative_prompt` is used instead + num_images_per_prompt (`int`, *optional*, defaults to 1): + The number of images to generate per prompt. + generator (`torch.Generator` or `List[torch.Generator]`, *optional*): + One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html) + to make generation deterministic. + latents (`torch.FloatTensor`, *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 will ge generated by sampling using the supplied random `generator`. + prompt_embeds (`torch.FloatTensor`, *optional*): + Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not + provided, text embeddings will be generated from `prompt` input argument. + negative_prompt_embeds (`torch.FloatTensor`, *optional*): + Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt + weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input + argument. + pooled_prompt_embeds (`torch.FloatTensor`, *optional*): + Pre-generated pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. + If not provided, pooled text embeddings will be generated from `prompt` input argument. + negative_pooled_prompt_embeds (`torch.FloatTensor`, *optional*): + Pre-generated negative pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt + weighting. If not provided, pooled negative_prompt_embeds will be generated from `negative_prompt` + input argument. + output_type (`str`, *optional*, defaults to `"pil"`): + The output format of the generate image. Choose between + [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`. + return_dict (`bool`, *optional*, defaults to `True`): + Whether or not to return a [`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] instead + of a plain tuple. + joint_attention_kwargs (`dict`, *optional*): + A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under + `self.processor` in + [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py). + callback_on_step_end (`Callable`, *optional*): + 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, + 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. + max_sequence_length (`int` defaults to 256): Maximum sequence length to use with the `prompt`. + pag_scale (`float`, *optional*, defaults to 3.0): + The scale factor for the perturbed attention guidance. If it is set to 0.0, the perturbed attention + guidance will not be used. + pag_adaptive_scale (`float`, *optional*, defaults to 0.0): + The adaptive scale factor for the perturbed attention guidance. If it is set to 0.0, `pag_scale` is + used. + + Examples: + + Returns: + [`~pipelines.stable_diffusion_3.StableDiffusion3PipelineOutput`] or `tuple`: + [`~pipelines.stable_diffusion_3.StableDiffusion3PipelineOutput`] if `return_dict` is True, otherwise a + `tuple`.

Existing autoencoder models have demonstrated impressive results at a moderate spatial compression ratio (e.g., 8x), but fail to maintain satisfactory reconstruction accuracy for high spatial compression ratios (e.g., 64x). We address this challenge by introducing two key techniques: (1) Residual Autoencoding, where we design our models to learn residuals based on the space-to-channel transformed features to alleviate the optimization difficulty of high spatial-compression autoencoders; (2) Decoupled High-Resolution Adaptation, an efficient decoupled three-phases training strategy for mitigating the generalization penalty of high spatial-compression autoencoders. With these designs, we improve the autoencoder's spatial compression ratio up to 128 while maintaining the reconstruction quality. Applying our DC-AE to latent diffusion models, we achieve significant speedup without accuracy drop. For example, on ImageNet 512x512, our DC-AE provides 19.1x inference speedup and 17.9x training speedup on H100 GPU for UViT-H while achieving a better FID, compared with the widely used SD-VAE-f8 autoencoder. Our code is available at [this https URL](https://github.com/mit-han-lab/efficientvit).* + +The following DCAE models are released and supported in Diffusers. + +| Diffusers format | Original format |

Sana can synthesize high-resolution, high-quality images with strong text-image alignment at a remarkably fast speed, deployable on laptop GPU. Core designs include: (1) Deep compression autoencoder: unlike traditional AEs, which compress images only 8×, we trained an AE that can compress images 32×, effectively reducing the number of latent tokens. (2) Linear DiT: we replace all vanilla attention in DiT with linear attention, which is more efficient at high resolutions without sacrificing quality. (3) Decoder-only text encoder: we replaced T5 with modern decoder-only small LLM as the text encoder and designed complex human instruction with in-context learning to enhance the image-text alignment. (4) Efficient training and sampling: we propose Flow-DPM-Solver to reduce sampling steps, with efficient caption labeling and selection to accelerate convergence. As a result, Sana-0.6B is very competitive with modern giant diffusion model (e.g. Flux-12B), being 20 times smaller and 100+ times faster in measured throughput.

However, the leading video generation models remain closed-source, resulting in a notable performance gap between industry capabilities and those available to the public. In this report, we introduce HunyuanVideo, an innovative open-source video foundation model that demonstrates performance in video generation comparable to, or even surpassing, that of leading closed-source models. HunyuanVideo encompasses a comprehensive framework that integrates several key elements, including data curation, advanced architectural design, progressive model scaling and training, and an efficient infrastructure tailored for large-scale model training and inference. As a result, we successfully trained a video generative model with over 13 billion parameters, making it the largest among all open-source models. We conducted extensive experiments and implemented a series of targeted designs to ensure high visual quality, motion dynamics, text-video alignment, and advanced filming techniques. According to evaluations by professionals, HunyuanVideo outperforms previous state-of-the-art models, including Runway Gen-3, Luma 1.6, and three top-performing Chinese video generative models. By releasing the code for the foundation model and its applications, we aim to bridge the gap between closed-source and open-source communities. This initiative will empower individuals within the community to experiment with their ideas, fostering a more dynamic and vibrant video generation ecosystem. The code is publicly available at [this https URL](https://github.com/Tencent/HunyuanVideo).* + + + +Make sure to check out the Schedulers [guide](../../using-diffusers/schedulers.md) to learn how to explore the tradeoff between scheduler speed and quality, and see the [reuse components across pipelines](../../using-diffusers/loading.md#reuse-a-pipeline) section to learn how to efficiently load the same components into multiple pipelines. + + + +Recommendations for inference: +- Both text encoders should be in `torch.float16`. +- Transformer should be in `torch.bfloat16`. +- VAE should be in `torch.float16`. +- `num_frames` should be of the form `4 * k + 1`, for example `49` or `129`. +- For smaller resolution images, try lower values of `shift` (between `2.0` to `5.0`) in the [Scheduler](https://huggingface.co/docs/diffusers/main/en/api/schedulers/flow_match_euler_discrete#diffusers.FlowMatchEulerDiscreteScheduler.shift). For larger resolution images, try higher values (between `7.0` and `12.0`). The default value is `7.0` for HunyuanVideo. +- For more information about supported resolutions and other details, please refer to the original repository

Autoquantization determines the best quantization strategy applicable to a model by comparing the performance of each technique on chosen input types and shapes. Currently, this can be used directly on the underlying modeling components.

For example, to not perform any quantization of the [`FluxTransformer2DModel`]'s first block, one would specify: `modules_to_not_convert=["single_transformer_blocks.0"]`. +- `kwargs`: A dict of keyword arguments to pass to the underlying quantization method which will be invoked based on `quant_type`. + +## Supported quantization types + +torchao supports weight-only quantization and weight and dynamic-activation quantization for int8, float3-float8, and uint1-uint7. + +Weight-only quantization stores the model weights in a specific low-bit data type but performs computation with a higher-precision data type, like `bfloat16`.

This lowers the memory requirements from model weights, while also lowering the memory overhead from activation computations.

With this change, we may also want to explore From 12fbe3f7dc1c11b74aa8fd4b190bd8216d8037fd Mon Sep 17 00:00:00 2001 From: hlky Date: Fri, 10 Jan 2025 04:45:42 +0000 Subject: [PATCH 333/639] Use Pipelines without unet (#10440) * Use Pipelines without unet * unet.config.in_channels * default_sample_size * is_unet_version_less_0_9_0 --------- Co-authored-by: Sayak Paul --- examples/community/adaptive_mask_inpainting.py | 14 +++++++++----- examples/community/composable_stable_diffusion.py | 12 ++++++++---- examples/community/instaflow_one_step.py | 12 ++++++++---- examples/community/ip_adapter_face_id.py | 12 ++++++++---- examples/community/llm_grounded_diffusion.py | 12 ++++++++---- examples/community/lpw_stable_diffusion.py | 12 ++++++++---- examples/community/lpw_stable_diffusion_xl.py | 6 +++++- examples/community/matryoshka.py | 12 ++++++++---- examples/community/pipeline_demofusion_sdxl.py | 6 +++++- examples/community/pipeline_fabric.py | 12 ++++++++---- .../pipeline_kolors_differential_img2img.py | 6 +++++- examples/community/pipeline_prompt2prompt.py | 12 ++++++++---- examples/community/pipeline_sdxl_style_aligned.py | 6 +++++- .../community/pipeline_stable_diffusion_boxdiff.py | 12 ++++++++---- .../community/pipeline_stable_diffusion_pag.py | 12 ++++++++---- ...eline_stable_diffusion_xl_controlnet_adapter.py | 6 +++++- ...able_diffusion_xl_controlnet_adapter_inpaint.py | 6 +++++- .../community/pipeline_stable_diffusion_xl_ipex.py | 6 +++++- examples/community/pipeline_zero1to3.py | 12 ++++++++---- examples/community/stable_diffusion_ipex.py | 12 ++++++++---- examples/community/stable_diffusion_reference.py | 14 +++++++++----- examples/community/stable_diffusion_repaint.py | 14 +++++++++----- .../community/stable_diffusion_tensorrt_img2img.py | 12 ++++++++---- .../community/stable_diffusion_tensorrt_inpaint.py | 12 ++++++++---- .../community/stable_diffusion_tensorrt_txt2img.py | 12 ++++++++---- .../animatediff/pipeline_animatediff_sdxl.py | 6 +++++- .../pipeline_if_img2img_superresolution.py | 2 +- .../pipeline_if_inpainting_superresolution.py | 2 +- .../deepfloyd_if/pipeline_if_superresolution.py | 2 +- .../alt_diffusion/pipeline_alt_diffusion.py | 12 ++++++++---- .../pipeline_alt_diffusion_img2img.py | 12 ++++++++---- .../pipeline_cycle_diffusion.py | 12 ++++++++---- .../pipeline_stable_diffusion_inpaint_legacy.py | 12 ++++++++---- src/diffusers/pipelines/kolors/pipeline_kolors.py | 6 +++++- .../pipelines/kolors/pipeline_kolors_img2img.py | 6 +++++- .../pipeline_leditspp_stable_diffusion.py | 12 ++++++++---- .../pipeline_leditspp_stable_diffusion_xl.py | 6 +++++- src/diffusers/pipelines/pag/pipeline_pag_kolors.py | 6 +++++- src/diffusers/pipelines/pag/pipeline_pag_sd.py | 12 ++++++++---- .../pipelines/pag/pipeline_pag_sd_img2img.py | 12 ++++++++---- .../pipelines/pag/pipeline_pag_sd_inpaint.py | 12 ++++++++---- src/diffusers/pipelines/pag/pipeline_pag_sd_xl.py | 6 +++++- .../pipeline_flax_stable_diffusion.py | 12 ++++++++---- .../pipeline_flax_stable_diffusion_inpaint.py | 12 ++++++++---- .../stable_diffusion/pipeline_stable_diffusion.py | 13 ++++++++----- .../pipeline_stable_diffusion_depth2img.py | 12 ++++++++---- .../pipeline_stable_diffusion_image_variation.py | 12 ++++++++---- .../pipeline_stable_diffusion_img2img.py | 12 ++++++++---- .../pipeline_stable_diffusion_inpaint.py | 14 +++++++++----- .../pipeline_stable_diffusion_diffedit.py | 12 ++++++++---- .../pipeline_stable_diffusion_xl_k_diffusion.py | 6 +++++- .../pipeline_stable_diffusion_safe.py | 12 ++++++++---- .../pipeline_stable_diffusion_xl.py | 6 +++++- ...ipeline_stable_diffusion_xl_instruct_pix2pix.py | 6 +++++- .../pipeline_stable_diffusion_xl_adapter.py | 6 +++++- .../pipeline_text_to_video_zero_sdxl.py | 6 +++++- 56 files changed, 377 insertions(+), 166 deletions(-) diff --git a/examples/community/adaptive_mask_inpainting.py b/examples/community/adaptive_mask_inpainting.py index b4f6b6ef668f..df736956485b 100644 --- a/examples/community/adaptive_mask_inpainting.py +++ b/examples/community/adaptive_mask_inpainting.py @@ -416,10 +416,14 @@ def __init__( " checker.

According to evaluations by professionals, HunyuanVideo outperforms previous state-of-the-art models, including Runway Gen-3, Luma 1.6, and three top-performing Chinese video generative models. By releasing the code for the foundation model and its applications, we aim to bridge the gap between closed-source and open-source communities.

+ + +Large image and video generation models, such as [FLUX.1-dev](https://huggingface.co/black-forest-labs/FLUX.1-dev) and [HunyuanVideo](https://huggingface.co/tencent/HunyuanVideo), can be an inference challenge for real-time applications and deployment because of their size. + +[ParaAttention](https://github.com/chengzeyi/ParaAttention) is a library that implements **context parallelism** and **first block cache**, and can be combined with other techniques (torch.compile, fp8 dynamic quantization), to accelerate inference. + +This guide will show you how to apply ParaAttention to FLUX.1-dev and HunyuanVideo on NVIDIA L20 GPUs. +No optimizations are applied for our baseline benchmark, except for HunyuanVideo to avoid out-of-memory errors. + +Our baseline benchmark shows that FLUX.1-dev is able to generate a 1024x1024 resolution image in 28 steps in 26.36 seconds, and HunyuanVideo is able to generate 129 frames at 720p resolution in 30 steps in 3675.71 seconds. + +> [!TIP] +> For even faster inference with context parallelism, try using NVIDIA A100 or H100 GPUs (if available) with NVLink support, especially when there is a large number of GPUs. + +## First Block Cache + +Caching the output of the transformers blocks in the model and reusing them in the next inference steps reduces the computation cost and makes inference faster. + +However, it is hard to decide when to reuse the cache to ensure quality generated images or videos. ParaAttention directly uses the **residual difference of the first transformer block output** to approximate the difference among model outputs. When the difference is small enough, the residual difference of previous inference steps is reused. In other words, the denoising step is skipped. + +This achieves a 2x speedup on FLUX.1-dev and HunyuanVideo inference with very good quality. + +

It is an important task in video generation but remains an open problem for generative models. This paper pushes the technical frontier of IPT2V in two directions that have not been resolved in the literature: (1) A tuning-free pipeline without tedious case-by-case finetuning, and (2) A frequency-aware heuristic identity-preserving Diffusion Transformer (DiT)-based control scheme. To achieve these goals, we propose **ConsisID**, a tuning-free DiT-based controllable IPT2V model to keep human-**id**entity **consis**tent in the generated video. Inspired by prior findings in frequency analysis of vision/diffusion transformers, it employs identity-control signals in the frequency domain, where facial features can be decomposed into low-frequency global features (e.g., profile, proportions) and high-frequency intrinsic features (e.g., identity markers that remain unaffected by pose changes). First, from a low-frequency perspective, we introduce a global facial extractor, which encodes the reference image and facial key points into a latent space, generating features enriched with low-frequency information. These features are then integrated into the shallow layers of the network to alleviate training challenges associated with DiT. Second, from a high-frequency perspective, we design a local facial extractor to capture high-frequency details and inject them into the transformer blocks, enhancing the model's ability to preserve fine-grained features. To leverage the frequency information for identity preservation, we propose a hierarchical training strategy, transforming a vanilla pre-trained video generation model into an IPT2V model. Extensive experiments demonstrate that our frequency-aware heuristic scheme provides an optimal control solution for DiT-based models. Thanks to this scheme, our **ConsisID** achieves excellent results in generating high-quality, identity-preserving videos, making strides towards more effective IPT2V.

+ + ## Running FP16 inference Flux can generate high-quality images with FP16 (i.e. to accelerate inference on Turing/Volta GPUs) but produces different outputs compared to FP32/BF16. The issue is that some activations in the text encoders have to be clipped when running in FP16, which affects the overall image. Forcing text encoders to run with FP32 inference thus removes this output difference. See [here](https://github.com/huggingface/diffusers/pull/9097#issuecomment-2272292516) for details.

The attention states are not very different between successive inference steps. The most prominent difference is in the spatial attention blocks, not as much in the temporal attention blocks, and finally the least in the cross attention blocks. Therefore, many cross attention computation blocks can be skipped, followed by the temporal and spatial attention blocks.

language +generation tasks and revolutionized human-machine interaction. +However, in the realm of image generation, a unified model capable of handling various tasks +within a single framework remains largely unexplored. In +this work, we introduce OmniGen, a new diffusion model +for unified image generation. OmniGen is characterized +by the following features: 1) Unification: OmniGen not +only demonstrates text-to-image generation capabilities but +also inherently supports various downstream tasks, such +as image editing, subject-driven generation, and visual conditional generation. 2) Simplicity: The architecture of +OmniGen is highly simplified, eliminating the need for additional plugins. Moreover, compared to existing diffusion +models, it is more user-friendly and can complete complex +tasks end-to-end through instructions without the need for +extra intermediate steps, greatly simplifying the image generation workflow. 3) Knowledge Transfer: Benefit from +learning in a unified format, OmniGen effectively transfers +knowledge across different tasks, manages unseen tasks and +domains, and exhibits novel capabilities. We also explore +the model’s reasoning capabilities and potential applications of the chain-of-thought mechanism. +This work represents the first attempt at a general-purpose image generation model, +and we will release our resources at https: +//github.com/VectorSpaceLab/OmniGen to foster future advancements.* + + + +Make sure to check out the Schedulers [guide](../../using-diffusers/schedulers.md) to learn how to explore the tradeoff between scheduler speed and quality, and see the [reuse components across pipelines](../../using-diffusers/loading.md#reuse-a-pipeline) section to learn how to efficiently load the same components into multiple pipelines. + + + +This pipeline was contributed by [staoxiao](https://github.com/staoxiao).

+ + +## Optimization when inputting multiple images + +For text-to-image task, OmniGen requires minimal memory and time costs (9GB memory and 31s for a 1024x1024 image on A800 GPU). +However, when using input images, the computational cost increases. + +Here are some guidelines to help you reduce computational costs when inputting multiple images. The experiments are conducted on an A800 GPU with two input images. + +Like other pipelines, you can reduce memory usage by offloading the model: `pipe.enable_model_cpu_offload()` or `pipe.enable_sequential_cpu_offload() `. +In OmniGen, you can also decrease computational overhead by reducing the `max_input_image_size`. +The memory consumption for different image sizes is shown in the table below: + +| Method | Memory Usage | +|---------------------------|--------------| +| max_input_image_size=1024 | 40GB | +| max_input_image_size=512 | 17GB | +| max_input_image_size=256 |

Lumina-Image 2.0 exhibits three key properties: (1) Unification – it adopts a unified architecture that treats text and image tokens as a joint sequence, enabling natural cross-modal interactions and facilitating task expansion. Besides, since high-quality captioners can provide semantically better-aligned text-image training pairs, we introduce a unified captioning system, UniCaptioner, which generates comprehensive and precise captions for the model. This not only accelerates model convergence but also enhances prompt adherence, variable-length prompt handling, and task generalization via prompt templates. (2) Efficiency – to improve the efficiency of the unified architecture, we develop a set of optimization techniques that improve semantic learning and fine-grained texture generation during training while incorporating inference-time acceleration strategies without compromising image quality. (3) Transparency – we open-source all training details, code, and models to ensure full reproducibility, aiming to bridge the gap between well-resourced closed-source research teams and independent developers.* + + + +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. + + + +## Lumina2Text2ImgPipeline + +[[autodoc]] Lumina2Text2ImgPipeline + -

Like other pipelines, you can reduce memory usage by offloading the model: `pipe.enable_model_cpu_offload()` or `pipe.enable_sequential_cpu_offload() `. In OmniGen, you can also decrease computational overhead by reducing the `max_input_image_size`. @@ -310,5 +315,3 @@ The memory consumption for different image sizes is shown in the table below: | max_input_image_size=512 | 17GB | | max_input_image_size=256 | 14GB | - - diff --git a/src/diffusers/models/embeddings.py b/src/diffusers/models/embeddings.py index bd3237c24c1c..c42fbbc9f0a3 100644 --- a/src/diffusers/models/embeddings.py +++ b/src/diffusers/models/embeddings.py @@ -1199,7 +1199,7 @@ def apply_rotary_emb( x_real, x_imag = x.reshape(*x.shape[:-1], -1, 2).unbind(-1) # [B, S, H, D//2] x_rotated = torch.stack([-x_imag, x_real], dim=-1).flatten(3) elif use_real_unbind_dim == -2: - # Used for Stable Audio + # Used for Stable Audio and OmniGen x_real, x_imag = x.reshape(*x.shape[:-1], 2, -1).unbind(-2) # [B, S, H, D//2] x_rotated = torch.cat([-x_imag, x_real], dim=-1) else: diff --git a/src/diffusers/models/transformers/transformer_omnigen.py b/src/diffusers/models/transformers/transformer_omnigen.py index 0774a3f2a6ee..8d5d1b3f8fea 100644 --- a/src/diffusers/models/transformers/transformer_omnigen.py +++ b/src/diffusers/models/transformers/transformer_omnigen.py @@ -13,17 +13,15 @@ # limitations under the License. import math -from typing import Any, Dict, List, Optional, Tuple, Union +from typing import Dict, List, Optional, Tuple, Union import torch +import torch.nn as nn import torch.nn.functional as F -import torch.utils.checkpoint -from torch import nn from ...configuration_utils import ConfigMixin, register_to_config -from ...loaders import PeftAdapterMixin -from ...utils import USE_PEFT_BACKEND, logging, scale_lora_layers -from ..attention_processor import Attention, AttentionProcessor +from ...utils import logging +from ..attention_processor import Attention from ..embeddings import TimestepEmbedding, Timesteps, get_2d_sincos_pos_embed from ..modeling_outputs import Transformer2DModelOutput from ..modeling_utils import ModelMixin @@ -34,39 +32,21 @@ class OmniGenFeedForward(nn.Module): - r""" - A feed-forward layer for OmniGen. - - Parameters: - hidden_size (`int`): - The dimensionality of the hidden layers in the model.

To understand what group offloading is, and + where it is beneficial, we need to first provide some context on how other supported offloading methods work. + + Typically, offloading is done at two levels: + - Module-level: In Diffusers, this can be enabled using the `ModelMixin::enable_model_cpu_offload()` method. It + works by offloading each component of a pipeline to the CPU for storage, and onloading to the accelerator device + when needed for computation. This method is more memory-efficient than keeping all components on the accelerator, + but the memory requirements are still quite high. For this method to work, one needs memory equivalent to size of + the model in runtime dtype + size of largest intermediate activation tensors to be able to complete the forward + pass. + - Leaf-level: In Diffusers, this can be enabled using the `ModelMixin::enable_sequential_cpu_offload()` method. It + works by offloading the lowest leaf-level parameters of the computation graph to the CPU for storage, and + onloading only the leafs to the accelerator device for computation. This uses the lowest amount of accelerator + memory, but can be slower due to the excessive number of device synchronizations. + + Group offloading is a middle ground between the two methods. It works by offloading groups of internal layers, + (either `torch.nn.ModuleList` or `torch.nn.Sequential`). This method uses lower memory than module-level + offloading. It is also faster than leaf-level/sequential offloading, as the number of device synchronizations is + reduced. + + Another supported feature (for CUDA devices with support for asynchronous data transfer streams) is the ability to + overlap data transfer and computation to reduce the overall execution time compared to sequential offloading. This + is enabled using layer prefetching with streams, i.e., the layer that is to be executed next starts onloading to + the accelerator device while the current layer is being executed - this increases the memory requirements slightly. + Note that this implementation also supports leaf-level offloading but can be made much faster when using streams. + + Args: + module (`torch.nn.Module`): + The module to which group offloading is applied. + onload_device (`torch.device`): + The device to which the group of modules are onloaded. + offload_device (`torch.device`, defaults to `torch.device("cpu")`): + The device to which the group of modules are offloaded.

However, the leading video generation models remain closed-source, resulting in a notable performance gap between industry capabilities and those available to the public. In this report, we introduce HunyuanVideo, an innovative open-source video foundation model that demonstrates performance in video generation comparable to, or even surpassing, that of leading closed-source models. HunyuanVideo encompasses a comprehensive framework that integrates several key elements, including data curation, advanced architectural design, progressive model scaling and training, and an efficient infrastructure tailored for large-scale model training and inference. As a result, we successfully trained a video generative model with over 13 billion parameters, making it the largest among all open-source models. We conducted extensive experiments and implemented a series of targeted designs to ensure high visual quality, motion dynamics, text-video alignment, and advanced filming techniques. According to evaluations by professionals, HunyuanVideo outperforms previous state-of-the-art models, including Runway Gen-3, Luma 1.6, and three top-performing Chinese video generative models. By releasing the code for the foundation model and its applications, we aim to bridge the gap between closed-source and open-source communities. This initiative will empower individuals within the community to experiment with their ideas, fostering a more dynamic and vibrant video generation ecosystem.

This model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and can run on consumer GPUs. Latent diffusion is the research on top of which Stable Diffusion was built. It was proposed in [High-Resolution Image Synthesis with Latent Diffusion Models](https://huggingface.co/papers/2112.10752) by Robin Rombach, Andreas Blattmann, Dominik Lorenz, Patrick Esser, Björn Ommer.

Recovering 3D depth from a single image is geometrically ill-posed and requires scene understanding, so it is not surprising that the rise of deep learning has led to a breakthrough. The impressive progress of monocular depth estimators has mirrored the growth in model capacity, from relatively modest CNNs to large Transformer architectures. Still, monocular depth estimators tend to struggle when presented with images with unfamiliar content and layout, since their knowledge of the visual world is restricted by the data seen during training, and challenged by zero-shot generalization to new domains. This motivates us to explore whether the extensive priors captured in recent generative diffusion models can enable better, more generalizable depth estimation. We introduce Marigold, a method for affine-invariant monocular depth estimation that is derived from Stable Diffusion and retains its rich prior knowledge. The estimator can be fine-tuned in a couple of days on a single GPU using only synthetic training data. It delivers state-of-the-art performance across a wide range of datasets, including over 20% performance gains in specific cases.

It is also higher in shaded regions and at discontinuities. + +## Conclusion + +We hope Marigold proves valuable for your downstream tasks, whether as part of a broader generative workflow or for +perception-based applications like 3D reconstruction. \ No newline at end of file diff --git a/src/diffusers/__init__.py b/src/diffusers/__init__.py index f4d395c7d011..71dd49886f6f 100644 --- a/src/diffusers/__init__.py +++ b/src/diffusers/__init__.py @@ -345,6 +345,7 @@ "Lumina2Text2ImgPipeline", "LuminaText2ImgPipeline", "MarigoldDepthPipeline", + "MarigoldIntrinsicsPipeline", "MarigoldNormalsPipeline", "MochiPipeline", "MusicLDMPipeline", @@ -845,6 +846,7 @@ Lumina2Text2ImgPipeline, LuminaText2ImgPipeline, MarigoldDepthPipeline, + MarigoldIntrinsicsPipeline, MarigoldNormalsPipeline, MochiPipeline, MusicLDMPipeline, diff --git a/src/diffusers/pipelines/__init__.py b/src/diffusers/pipelines/__init__.py index 0410fef30e7e..8e7f9d68a5d4 100644 --- a/src/diffusers/pipelines/__init__.py +++ b/src/diffusers/pipelines/__init__.py @@ -261,6 +261,7 @@ _import_structure["marigold"].extend( [ "MarigoldDepthPipeline", + "MarigoldIntrinsicsPipeline", "MarigoldNormalsPipeline", ] ) @@ -603,6 +604,7 @@ from .lumina2 import Lumina2Text2ImgPipeline from .marigold import ( MarigoldDepthPipeline, + MarigoldIntrinsicsPipeline, MarigoldNormalsPipeline, ) from .mochi import MochiPipeline diff --git a/src/diffusers/pipelines/marigold/__init__.py b/src/diffusers/pipelines/marigold/__init__.py index b5ae03adfc11..168a8276be4e 100644 --- a/src/diffusers/pipelines/marigold/__init__.py +++ b/src/diffusers/pipelines/marigold/__init__.py @@ -23,6 +23,7 @@ else: _import_structure["marigold_image_processing"] = ["MarigoldImageProcessor"] _import_structure["pipeline_marigold_depth"] = ["MarigoldDepthOutput", "MarigoldDepthPipeline"] + _import_structure["pipeline_marigold_intrinsics"] = ["MarigoldIntrinsicsOutput", "MarigoldIntrinsicsPipeline"] _import_structure["pipeline_marigold_normals"] = ["MarigoldNormalsOutput", "MarigoldNormalsPipeline"] if TYPE_CHECKING or DIFFUSERS_SLOW_IMPORT: @@ -35,6 +36,7 @@ else: from .marigold_image_processing import MarigoldImageProcessor from .pipeline_marigold_depth import MarigoldDepthOutput, MarigoldDepthPipeline + from .pipeline_marigold_intrinsics import MarigoldIntrinsicsOutput, MarigoldIntrinsicsPipeline from .pipeline_marigold_normals import MarigoldNormalsOutput, MarigoldNormalsPipeline else: diff --git a/src/diffusers/pipelines/marigold/marigold_image_processing.py b/src/diffusers/pipelines/marigold/marigold_image_processing.py index 51b9983db6f6..0723014ad37b 100644 --- a/src/diffusers/pipelines/marigold/marigold_image_processing.py +++ b/src/diffusers/pipelines/marigold/marigold_image_processing.py @@ -1,4 +1,22 @@ -from typing import List, Optional, Tuple, Union +# Copyright 2023-2025 Marigold Team, ETH Zürich.

Code + +```python +image = remote_decode( + endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=torch.randn([1, 4, 64, 64], dtype=torch.float16), + scaling_factor=0.18215, +) +``` + +
+ +
+ +
+ +Usage for Flux is slightly different. Flux latents are packed so we need to send the `height` and `width`. + +
Code + +```python +image = remote_decode( + endpoint="https://whhx50ex1aryqvw6.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=torch.randn([1, 4096, 64], dtype=torch.float16), + height=1024, + width=1024, + scaling_factor=0.3611, + shift_factor=0.1159, +) +``` + +
+ +
+ +
+ +Finally, an example for HunyuanVideo. + +
Code + +```python +video = remote_decode( + endpoint="https://o7ywnmrahorts457.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=torch.randn([1, 16, 3, 40, 64], dtype=torch.float16), + output_type="mp4", +) +with open("video.mp4", "wb") as f: + f.write(video) +``` + +
+ +
+ +
+ + +### Generation + +But we want to use the VAE on an actual pipeline to get an actual image, not random noise. The example below shows how to do it with SD v1.5. + +
Code + +```python +from diffusers import StableDiffusionPipeline + +pipe = StableDiffusionPipeline.from_pretrained( + "stable-diffusion-v1-5/stable-diffusion-v1-5", + torch_dtype=torch.float16, + variant="fp16", + vae=None, +).to("cuda") + +prompt = "Strawberry ice cream, in a stylish modern glass, coconut, splashing milk cream and honey, in a gradient purple background, fluid motion, dynamic movement, cinematic lighting, Mysterious" + +latent = pipe( + prompt=prompt, + output_type="latent", +).images +image = remote_decode( + endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=latent, + scaling_factor=0.18215, +) +image.save("test.jpg") +``` + +
+ +
+ +
+ +Here’s another example with Flux. + +
Code + +```python +from diffusers import FluxPipeline + +pipe = FluxPipeline.from_pretrained( + "black-forest-labs/FLUX.1-schnell", + torch_dtype=torch.bfloat16, + vae=None, +).to("cuda") + +prompt = "Strawberry ice cream, in a stylish modern glass, coconut, splashing milk cream and honey, in a gradient purple background, fluid motion, dynamic movement, cinematic lighting, Mysterious" + +latent = pipe( + prompt=prompt, + guidance_scale=0.0, + num_inference_steps=4, + output_type="latent", +).images +image = remote_decode( + endpoint="https://whhx50ex1aryqvw6.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=latent, + height=1024, + width=1024, + scaling_factor=0.3611, + shift_factor=0.1159, +) +image.save("test.jpg") +``` + +
+ +
+ +
+ +Here’s an example with HunyuanVideo. + +
Code + +```python +from diffusers import HunyuanVideoPipeline, HunyuanVideoTransformer3DModel + +model_id = "hunyuanvideo-community/HunyuanVideo" +transformer = HunyuanVideoTransformer3DModel.from_pretrained( + model_id, subfolder="transformer", torch_dtype=torch.bfloat16 +) +pipe = HunyuanVideoPipeline.from_pretrained( + model_id, transformer=transformer, vae=None, torch_dtype=torch.float16 +).to("cuda") + +latent = pipe( + prompt="A cat walks on the grass, realistic", + height=320, + width=512, + num_frames=61, + num_inference_steps=30, + output_type="latent", +).frames + +video = remote_decode( + endpoint="https://o7ywnmrahorts457.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=latent, + output_type="mp4", +) + +if isinstance(video, bytes): + with open("video.mp4", "wb") as f: + f.write(video) +``` + +
+ +
+ +
+ + +### Queueing + +One of the great benefits of using a remote VAE is that we can queue multiple generation requests. While the current latent is being processed for decoding, we can already queue another one. This helps improve concurrency. + + +
Code + +```python +import queue +import threading +from IPython.display import display +from diffusers import StableDiffusionPipeline + +def decode_worker(q: queue.Queue): + while True: + item = q.get() + if item is None: + break + image = remote_decode( + endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/", + tensor=item, + scaling_factor=0.18215, + ) + display(image) + q.task_done() + +q = queue.Queue() +thread = threading.Thread(target=decode_worker, args=(q,), daemon=True) +thread.start() + +def decode(latent: torch.Tensor): + q.put(latent) + +prompts = [ + "Blueberry ice cream, in a stylish modern glass , ice cubes, nuts, mint leaves, splashing milk cream, in a gradient purple background, fluid motion, dynamic movement, cinematic lighting, Mysterious", + "Lemonade in a glass, mint leaves, in an aqua and white background, flowers, ice cubes, halo, fluid motion, dynamic movement, soft lighting, digital painting, rule of thirds composition, Art by Greg rutkowski, Coby whitmore", + "Comic book art, beautiful, vintage, pastel neon colors, extremely detailed pupils, delicate features, light on face, slight smile, Artgerm, Mary Blair, Edmund Dulac, long dark locks, bangs, glowing, fashionable style, fairytale ambience, hot pink.", + "Masterpiece, vanilla cone ice cream garnished with chocolate syrup, crushed nuts, choco flakes, in a brown background, gold, cinematic lighting, Art by WLOP", + "A bowl of milk, falling cornflakes, berries, blueberries, in a white background, soft lighting, intricate details, rule of thirds, octane render, volumetric lighting", + "Cold Coffee with cream, crushed almonds, in a glass, choco flakes, ice cubes, wet, in a wooden background, cinematic lighting, hyper realistic painting, art by Carne Griffiths, octane render, volumetric lighting, fluid motion, dynamic movement, muted colors,", +] + +pipe = StableDiffusionPipeline.from_pretrained( + "Lykon/dreamshaper-8", + torch_dtype=torch.float16, + vae=None, +).to("cuda") + +pipe.unet = pipe.unet.to(memory_format=torch.channels_last) +pipe.unet = torch.compile(pipe.unet, mode="reduce-overhead", fullgraph=True) + +_ = pipe( + prompt=prompts[0], + output_type="latent", +) + +for prompt in prompts: + latent = pipe( + prompt=prompt, + output_type="latent", + ).images + decode(latent) + +q.put(None) +thread.join() +``` + +

2001 From: Teriks Date: Mon, 3 Mar 2025 07:30:39 -0600 Subject: [PATCH 518/639] Fix SD2.X clip single file load projection_dim (#10770) * Fix SD2.X clip single file load projection_dim Infer projection_dim from the checkpoint before loading from pretrained, override any incorrect hub config. Hub configuration for SD2.X specifies projection_dim=512 which is incorrect for SD2.X checkpoints loaded from civitai and similar. Exception was previously thrown upon attempting to load_model_dict_into_meta for SD2.X single file checkpoints. Such LDM models usually require projection_dim=1024 * convert_open_clip_checkpoint use hidden_size for text_proj_dim * convert_open_clip_checkpoint, revert checkpoint[text_proj_key].shape[1] -> [0]

To make sure offloading works as expected, you should consider moving the pipeline back to CPU: `pipeline.to('cpu')` or removing the move altogether if you use offloading." ) diff --git a/src/diffusers/quantizers/bitsandbytes/bnb_quantizer.py b/src/diffusers/quantizers/bitsandbytes/bnb_quantizer.py index f4aa1504534c..689d8e4256c2 100644 --- a/src/diffusers/quantizers/bitsandbytes/bnb_quantizer.py +++ b/src/diffusers/quantizers/bitsandbytes/bnb_quantizer.py @@ -61,7 +61,7 @@ def __init__(self, quantization_config, **kwargs): self.modules_to_not_convert = self.quantization_config.llm_int8_skip_modules def validate_environment(self, *args, **kwargs): - if not torch.cuda.is_available(): + if not (torch.cuda.is_available() or torch.xpu.is_available()): raise RuntimeError("No GPU found.

+ +[SANA-Sprint: One-Step Diffusion with Continuous-Time Consistency Distillation](https://huggingface.co/papers/2503.09641) from NVIDIA, MIT HAN Lab, and Hugging Face by Junsong Chen, Shuchen Xue, Yuyang Zhao, Jincheng Yu, Sayak Paul, Junyu Chen, Han Cai, Enze Xie, Song Han + +The abstract from the paper is: + +*This paper presents SANA-Sprint, an efficient diffusion model for ultra-fast text-to-image (T2I) generation. SANA-Sprint is built on a pre-trained foundation model and augmented with hybrid distillation, dramatically reducing inference steps from 20 to 1-4. We introduce three key innovations: (1) We propose a training-free approach that transforms a pre-trained flow-matching model for continuous-time consistency distillation (sCM), eliminating costly training from scratch and achieving high training efficiency. Our hybrid distillation strategy combines sCM with latent adversarial distillation (LADD): sCM ensures alignment with the teacher model, while LADD enhances single-step generation fidelity. (2) SANA-Sprint is a unified step-adaptive model that achieves high-quality generation in 1-4 steps, eliminating step-specific training and improving efficiency. (3) We integrate ControlNet with SANA-Sprint for real-time interactive image generation, enabling instant visual feedback for user interaction. SANA-Sprint establishes a new Pareto frontier in speed-quality tradeoffs, achieving state-of-the-art performance with 7.59 FID and 0.74 GenEval in only 1 step — outperforming FLUX-schnell (7.94 FID / 0.71 GenEval) while being 10× faster (0.1s vs 1.1s on H100). It also achieves 0.1s (T2I) and 0.25s (ControlNet) latency for 1024×1024 images on H100, and 0.31s (T2I) on an RTX 4090, showcasing its exceptional efficiency and potential for AI-powered consumer applications (AIPC). Code and pre-trained models will be open-sourced.* + + + +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. + + + +This pipeline was contributed by [lawrence-cj](https://github.com/lawrence-cj), [shuchen Xue](https://github.com/scxue) and [Enze Xie](https://github.com/xieenze).

This is enabled using layer prefetching with CUDA streams. The next layer to be executed is loaded onto the accelerator device while the current layer is being executed - this increases the memory requirements slightly. Group offloading also supports leaf-level offloading (equivalent to sequential CPU offloading) but can be made much faster when using streams. + + +- Group offloading may not work with all models out-of-the-box. If the forward implementations of the model contain weight-dependent device-casting of inputs, it may clash with the offloading mechanism's handling of device-casting. +- The `offload_type` parameter can be set to either `block_level` or `leaf_level`. `block_level` offloads groups of `torch::nn::ModuleList` or `torch::nn:Sequential` modules based on a configurable attribute `num_blocks_per_group`. For example, if you set `num_blocks_per_group=2` on a standard transformer model containing 40 layers, it will onload/offload 2 layers at a time for a total of 20 onload/offloads. This drastically reduces the VRAM requirements. `leaf_level` offloads individual layers at the lowest level, which is equivalent to sequential offloading. However, unlike sequential offloading, group offloading can be made much faster when using streams, with minimal compromise to end-to-end generation time. +- The `use_stream` parameter can be used with CUDA devices to enable prefetching layers for onload. It defaults to `False`. Layer prefetching allows overlapping computation and data transfer of model weights, which drastically reduces the overall execution time compared to other offloading methods. However, it can increase the CPU RAM usage significantly. Ensure that available CPU RAM that is at least twice the size of the model when setting `use_stream=True`. You can find more information about CUDA streams [here](https://pytorch.org/docs/stable/generated/torch.cuda.Stream.html) +- If specifying `use_stream=True` on VAEs with tiling enabled, make sure to do a dummy forward pass (possibly with dummy inputs) before the actual inference to avoid device-mismatch errors.

Please open an issue if you encounter any problems. +- The parameter `low_cpu_mem_usage` can be set to `True` to reduce CPU memory usage when using streams for group offloading. This is useful when the CPU memory is the bottleneck, but it may counteract the benefits of using streams and increase the overall execution time. The CPU memory savings come from creating pinned-tensors on-the-fly instead of pre-pinning them.

Sometimes, the forward implementations of the model might contain internal typecasting of weight values. Such implementations are not supported due to the currently simplistic implementation of layerwise casting, which assumes that the forward pass is independent of the weight precision and that the input dtypes are always in `compute_dtype`. An example of an incompatible implementation can be found [here](https://github.com/huggingface/transformers/blob/7f5077e53682ca855afc826162b204ebf809f1f9/src/transformers/models/t5/modeling_t5.py#L294-L299). +- Layerwise casting may fail on custom modeling implementations that make use of [PEFT](https://github.com/huggingface/peft) layers. Some minimal checks to handle this case is implemented but is not extensively tested or guaranteed to work in all cases. +- It can be also be applied partially to specific layers of a model. Partially applying layerwise casting can either be done manually by calling the `apply_layerwise_casting` function on specific internal modules, or by specifying the `skip_modules_pattern` and `skip_modules_classes` parameters for a root module. These parameters are particularly useful for layers such as normalization and modulation. + + + ## Channels-last memory format The channels-last memory format is an alternative way of ordering NCHW tensors in memory to preserve dimension ordering. Channels-last tensors are ordered in such a way that the channels become the densest dimension (storing images pixel-per-pixel).
