# LinFusion
## 论文
LinFusion: 1 GPU, 1 Minute, 16K Image
- https://arxiv.org/abs/2409.02097
## 模型结构
作者将所提出的 Generalized Linear Attention 模块集成到 SD 的架构中，替换原始的 Self-Attention 模块，生成的模型称为 LinFusion。使用知识蒸馏策略，只训练线性注意模块 50K 步，LinFusion 的性能即可与原始 SD 相当甚至更好，同时显著降低了时间和显存占用的复杂度。
<div align=center>
<img src="./assets/linfusin_overview.png"/>
</div>
## 算法原理
为了得到具有线性计算复杂度的 Diffusion Backbone，一个简单的方案是使用 Mamba2 替换所有的 Self-Attention，如图 4 (a) 所示。作者使用双向的 SSM 来确保当前位置可以从后续位置访问信息。SD 中的 Self-Attention 模块不包含 Mamba2 中的门控操作或者 RMS-Norm。作者为了保持一致性，就删除了这些结构，导致性能略有提高。

## Supported Models
1. `Yuanshi/LinFusion-1-5`: For Stable Diffusion v-1.5 and its variants. <a href="https://huggingface.co/Yuanshi/LinFusion-1-5"><img src="https://img.shields.io/badge/%F0%9F%A4%97-LinFusion for SD v1.5-yellow"></a>
1. `Yuanshi/LinFusion-2-1`: For Stable Diffusion v-2.1 and its variants. <a href="https://huggingface.co/Yuanshi/LinFusion-2-1"><img src="https://img.shields.io/badge/%F0%9F%A4%97-LinFusion for SD v2.1-yellow"></a>
1. `Yuanshi/LinFusion-XL`: For Stable Diffusion XL and its variants. <a href="https://huggingface.co/Yuanshi/LinFusion-XL"><img src="https://img.shields.io/badge/%F0%9F%A4%97-LinFusion for SD XL-yellow"></a>
## Quick Start
* If you have not, install [PyTorch](https://pytorch.org/get-started/locally/) and [diffusers](https://huggingface.co/docs/diffusers/index).
* Clone this repo to your project directory:
``` bash
git clone https://github.com/Huage001/LinFusion.git
```
* **You only need two lines!**
```diff
from diffusers import AutoPipelineForText2Image
import torch
+ from src.linfusion import LinFusion
sd_repo = "Lykon/dreamshaper-8"
pipeline = AutoPipelineForText2Image.from_pretrained(
sd_repo, torch_dtype=torch.float16, variant="fp16"
).to(torch.device("cuda"))
+ linfusion = LinFusion.construct_for(pipeline)
image = pipeline(
"An astronaut floating in space. Beautiful view of the stars and the universe in the background.",
generator=torch.manual_seed(123)
).images[0]
```
`LinFusion.construct_for(pipeline)` will return a LinFusion model that matches the pipeline's structure. And this LinFusion model will **automatically mount to** the pipeline's forward function.
* `examples/inference/basic_usage.ipynb` shows a basic text-to-image example.
## Gradio Demo
* Currently, you can try LinFusion for SD-v1.5 online [here](https://huggingface.co/spaces/Huage001/LinFusion-SD-v1.5). Text-to-image, image-to-image, and IP-Adapter are supported currently.
* We are building Gradio local demos for more base models and applications, so that everyone can deploy the demos locally.
## Ultrahigh-Resolution Generation
From the perspective of efficiency, our method supports high-resolution generation such as 16K images. Nevertheless, directly applying diffusion models trained on low resolutions for higher-resolution generation can result in content distortion and duplication. To tackle this challenge, we apply following techniques:
* [SDEdit](https://huggingface.co/docs/diffusers/v0.30.2/en/api/pipelines/stable_diffusion/img2img#image-to-image). **The basic idea is to generate a low-resolution result at first, based on which we gradually upscale the image.**
**Please refer to `examples/inference/ultra_text2image_w_sdedit.ipynb` for an example.**
* [DemoFusion](https://github.com/PRIS-CV/DemoFusion). It also generates high-resolution images from low-resolution results. Latents of the low-resolution generation are reused for high-resolution generation. Dilated convolutions are involved. Compared with the original version:
1. We can generate high-resolution directly with the help of LinFusion instead of using patch-wise strategies.
2. Insights in SDEdit are also applied here, so that the high-resolution branch does not need to go through full denoising steps.
3. Image are upscaled to 2x, 4x, 8x, ... resolutions instead of 1x, 2x, 3x, ...
**Please refer to `examples/inference/ultra_text2image_sdxl.ipynb` for an example of high-resolution text-to-image generation** (first generate 1024 resolution, then generate 2048, 4096, 8192, etc) **and `examples/inference/superres_sdxl.ipynb` for an example of image super resolution** (directly upscale to the target resolution, generally 2x is recommended and using it multiple times if you want higher scales).
* Above codes for 16K image generation require a GPU with 80G video memory. **If you encounter OOM issues, you may consider `examples/inference/superres_sdxl_low_w_mem.ipynb`, which requires only 24G video memory.** We achieve this by 1) chunked forward of classifier-free guidance inference, 2) chunked forward of feed-forward network in Transformer blocks, 3) in-placed activation functions in ResNets, and 4) caching UNet residuals on CPU.
* [DistriFusion](https://github.com/mit-han-lab/distrifuser). Alternatively, if you have multiple GPU cards, you can try integrating LinFusion to DistriFusion, which achieves **more significant acceleration due to its linearity and thus almost constant communication cost**. You can run an minimal example with:
```bash
torchrun --nproc_per_node=$N_GPUS -m examples.inference.sdxl_distrifusion_example
```
* We are working on integrating LinFusion with more advanced approaches that are dedicated on high-resolution extension! **Feel free to create pull requests if you come up with better solutions!**
## Training
* Before training, make sure you have the packages shown in `requirements.txt` installed:
```bash
pip install -r requirements.txt
```
* Training codes for Stable Diffusion v-1.5, v-2.1, and their variants are released in `src/train/distill.py`. We present an exampler running script in `examples/train/distill.sh`. You can run it on a 8-GPU machine via:
```bash
bash ./examples/training/distill.sh
```
The codes will download `bhargavsdesai/laion_improved_aesthetics_6.5plus_with_images` [dataset](https://huggingface.co/datasets/bhargavsdesai/laion_improved_aesthetics_6.5plus_with_images) automatically to `~/.cache` directory by default if there is not, which contains 169k images and requires ~75 GB disk space.
We use fp16 precision and 512 resolution for Stable Diffusion v-1.5 and bf16 precision and 768 resolution for Stable Diffusion v-2.1.
* Training codes for Stable Diffusion XL are released in `src/train/distill_xl.py`. We present an exampler running script in `examples/train/distill_xl.sh`. You can run it on a 8-GPU machine via:
```bash
bash ./examples/training/distill_xl.sh
```
## Evaluation
Following [GigaGAN](https://github.com/mingukkang/GigaGAN/tree/main/evaluation), we use 30,000 COCO captions to generate 30,000 images for evaluation. FID against COCO val2014 is reported as a metric, and CLIP text cosine similarity is used to reflect the text-image alignment.
* To evaluate LinFusion, first install the required packages:
```bash
pip install git+https://github.com/openai/CLIP.git
pip install click clean-fid open_clip_torch
```
* Download and unzip COCO val2014 to `/path/to/coco`:
```bash
wget http://images.cocodataset.org/zips/val2014.zip
unzip val2014.zip -d /path/to/coco
```
* Run `examples/eval/eval.sh` to generate images for evaluation. You may need to specify `outdir`, `repo_id`, `resolution`, etc.
```bash
bash examples/eval/eval.sh
```
* Run `examples/eval/calculate_metrics.sh` to calculate the metrics. You may need to specify `/path/to/coco`, `fake_dir`, etc.
```bash
bash examples/eval/calculate_metrics.sh
```
## ToDo
- [x] Stable Diffusion 1.5 support.
- [x] Stable Diffusion 2.1 support.
- [x] Stable Diffusion XL support.
- [x] Release training code for LinFusion.
- [x] Release evaluation code for LinFusion.
- [ ] Gradio local interface.
## Acknowledgement
* We extend our gratitude to the authors of [SDEdit](https://huggingface.co/docs/diffusers/v0.30.2/en/api/pipelines/stable_diffusion/img2img#image-to-image), [DemoFusion](https://github.com/PRIS-CV/DemoFusion), and [DistriFusion](https://github.com/mit-han-lab/distrifuser) for their contributions, which inspire us a lot on applying LinFusion for high-resolution generation.
* Our evaluation codes are adapted from [SiD-LSG](https://github.com/mingyuanzhou/SiD-LSG) and [GigaGAN](https://github.com/mingukkang/GigaGAN/tree/main/evaluation).
* We thank [@Adamdad](https://github.com/Adamdad), [@yu-rp](https://github.com/yu-rp), and [@czg1225](https://github.com/czg1225) for valuable discussions.
