-## Introduction
-
-Welcome to the magic world of Diffusion models! DiffSynth-Studio is an open-source Diffusion model engine developed and maintained by [ModelScope](https://www.modelscope.cn/) team. We aim to foster technical innovation through framework development, bring together the power of the open-source community, and explore the limits of generative models!
-
-DiffSynth currently includes two open-source projects:
-* [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio): Focused on aggressive technical exploration, for academia, providing support for more cutting-edge model capabilities.
-* [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine): Focused on stable model deployment, for industry, offering higher computing performance and more stable features.
-
-[DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) and [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine) are the core projects behind ModelScope [AIGC zone](https://modelscope.cn/aigc/home), offering powerful AI content generation abilities. Come and try our carefully designed features and start your AI creation journey!
-
-## Installation
-
-Install from source (recommended):
-
-```
-git clone https://github.com/modelscope/DiffSynth-Studio.git
-cd DiffSynth-Studio
-pip install -e .
-```
-
-
-Other installation methods
-
-Install from PyPI (version updates may be delayed; for latest features, install from source)
-
-```
-pip install diffsynth
-```
-
-If you meet problems during installation, they might be caused by upstream dependencies. Please check the docs of these packages:
-
-* [torch](https://pytorch.org/get-started/locally/)
-* [sentencepiece](https://github.com/google/sentencepiece)
-* [cmake](https://cmake.org)
-* [cupy](https://docs.cupy.dev/en/stable/install.html)
-
-
-
-## Basic Framework
-
-DiffSynth-Studio redesigns the inference and training pipelines for mainstream Diffusion models (including FLUX, Wan, etc.), enabling efficient memory management and flexible model training.
-
-### Qwen-Image Series (🔥New Model)
-
-Details: [./examples/qwen_image/](./examples/qwen_image/)
-
-
-
-
-
-Quick Start
-
-```python
-from diffsynth.pipelines.qwen_image import QwenImagePipeline, ModelConfig
-from PIL import Image
-import torch
-
-pipe = QwenImagePipeline.from_pretrained(
- torch_dtype=torch.bfloat16,
- device="cuda",
- model_configs=[
- ModelConfig(model_id="Qwen/Qwen-Image", origin_file_pattern="transformer/diffusion_pytorch_model*.safetensors"),
- ModelConfig(model_id="Qwen/Qwen-Image", origin_file_pattern="text_encoder/model*.safetensors"),
- ModelConfig(model_id="Qwen/Qwen-Image", origin_file_pattern="vae/diffusion_pytorch_model.safetensors"),
- ],
- tokenizer_config=ModelConfig(model_id="Qwen/Qwen-Image", origin_file_pattern="tokenizer/"),
-)
-prompt = "A detailed portrait of a girl underwater, wearing a blue flowing dress, hair gently floating, clear light and shadow, surrounded by bubbles, calm expression, fine details, dreamy and beautiful."
-image = pipe(
- prompt, seed=0, num_inference_steps=40,
- # edit_image=Image.open("xxx.jpg").resize((1328, 1328)) # For Qwen-Image-Edit
-)
-image.save("image.jpg")

-- **Nov 15, 2023.** We propose FastBlend, a powerful video deflickering algorithm.
- - The sd-webui extension is released on [GitHub](https://github.com/Artiprocher/sd-webui-fastblend).
- - Demo videos are shown on Bilibili, including three tasks.
- - [Video deflickering](https://www.bilibili.com/video/BV1d94y1W7PE)
- - [Video interpolation](https://www.bilibili.com/video/BV1Lw411m71p)
- - [Image-driven video rendering](https://www.bilibili.com/video/BV1RB4y1Z7LF)
- - The technical report is released on [arXiv](https://arxiv.org/abs/2311.09265).
- - An unofficial ComfyUI extension developed by other users is released on [GitHub](https://github.com/AInseven/ComfyUI-fastblend).
-
-- **Oct 1, 2023.** We release an early version of this project, namely FastSDXL. A try for building a diffusion engine.
- - The source codes are released on [GitHub](https://github.com/Artiprocher/FastSDXL).
- - FastSDXL includes a trainable OLSS scheduler for efficiency improvement.
- - The original repo of OLSS is [here](https://github.com/alibaba/EasyNLP/tree/master/diffusion/olss_scheduler).
- - The technical report (CIKM 2023) is released on [arXiv](https://arxiv.org/abs/2305.14677).
- - A demo video is shown on [Bilibili](https://www.bilibili.com/video/BV1w8411y7uj).
- - Since OLSS requires additional training, we don't implement it in this project.
-
-- **Aug 29, 2023.** We propose DiffSynth, a video synthesis framework.
- - [Project Page](https://ecnu-cilab.github.io/DiffSynth.github.io/).
- - The source codes are released in [EasyNLP](https://github.com/alibaba/EasyNLP/tree/master/diffusion/DiffSynth).
- - The technical report (ECML PKDD 2024) is released on [arXiv](https://arxiv.org/abs/2308.03463).

-## 简介
-
-欢迎来到 Diffusion 模型的魔法世界!DiffSynth-Studio 是由[魔搭社区](https://www.modelscope.cn/)团队开发和维护的开源 Diffusion 模型引擎。我们期望以框架建设孵化技术创新,凝聚开源社区的力量,探索生成式模型技术的边界!
-
-DiffSynth 目前包括两个开源项目:
-* [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio): 聚焦于激进的技术探索,面向学术界,提供更前沿的模型能力支持。
-* [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine): 聚焦于稳定的模型部署,面向工业界,提供更高的计算性能与更稳定的功能。
-
-[DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) 与 [DiffSynth-Engine](https://github.com/modelscope/DiffSynth-Engine) 作为魔搭社区 [AIGC 专区](https://modelscope.cn/aigc/home) 的核心技术支撑,提供了强大的AI生成内容能力。欢迎体验我们精心打造的产品化功能,开启您的AI创作之旅!
-

- Calculate the 3D rope index based on image and video's temporal, height and width in LLM.
-
- Explanation:
- Each embedding sequence contains vision embedding and text embedding or just contains text embedding.
-
- For pure text embedding sequence, the rotary position embedding has no difference with modern LLMs.
- Examples:
- input_ids: [T T T T T], here T is for text.
- temporal position_ids: [0, 1, 2, 3, 4]
- height position_ids: [0, 1, 2, 3, 4]
- width position_ids: [0, 1, 2, 3, 4]
-
- For vision and text embedding sequence, we calculate 3D rotary position embedding for vision part
- and 1D rotary position embedding for text part.
- Examples:
- Temporal (Time): 3 patches, representing different segments of the video in time.
- Height: 2 patches, dividing each frame vertically.
- Width: 2 patches, dividing each frame horizontally.
- We also have some important parameters:
- fps (Frames Per Second): The video's frame rate, set to 1. This means one frame is processed each second.
- tokens_per_second: This is a crucial parameter. It dictates how many "time-steps" or "temporal tokens" are conceptually packed into a one-second interval of the video. In this case, we have 25 tokens per second. So each second of the video will be represented with 25 separate time points. It essentially defines the temporal granularity.
- temporal_patch_size: The number of frames that compose one temporal patch. Here, it's 2 frames.
- interval: The step size for the temporal position IDs, calculated as tokens_per_second * temporal_patch_size / fps. In this case, 25 * 2 / 1 = 50. This means that each temporal patch will be have a difference of 50 in the temporal position IDs.
- input_ids: [V V V V V V V V V V V V T T T T T], here V is for vision.
- vision temporal position_ids: [0, 0, 0, 0, 50, 50, 50, 50, 100, 100, 100, 100]
- vision height position_ids: [0, 0, 1, 1, 0, 0, 1, 1, 0, 0, 1, 1]
- vision width position_ids: [0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1]
- text temporal position_ids: [101, 102, 103, 104, 105]
- text height position_ids: [101, 102, 103, 104, 105]
- text width position_ids: [101, 102, 103, 104, 105]
- Here we calculate the text start position_ids as the max vision position_ids plus 1.
