Stable Diffusion WebUI 是一款基于深度学习的图像生成工具,根据用户的输入文本或图像,生成高质量的新图像,特点如下:
- 支持多种图像生成任务,如人脸生成、风格迁移、图像修复、图像超分辨率等。
- 使用稳定扩散模型(Stable Diffusion Model)作为图像生成的核心算法,该模型具有高效、稳定、可控的优势。
- 提供友好的 Web 界面,用户可以通过浏览器访问和使用,无需安装任何软件或插件。
- 支持自定义参数和模型,用户可以根据自己的需求和喜好,调整图像生成的效果和风格。
Stable Diffusion WebUI 是一款适合各类用户的图像生成工具,无论你是专业的设计师、艺术家、摄影师,还是普通的爱好者、学习者,都可以在这里发挥你的创意和想象力,生成你想要的图像。
运行 WebUI 环境 :
source venv/bin/activate
python -u launch.py --listen--port9301--xformers --no-half-vae --enable-insecure-extension-access --theme dark --gradio-queue
nohup python -u launch.py --listen--port9301--xformers --no-half-vae --enable-insecure-extension-access --theme dark --gradio-queue > nohup.62.out &

1. 环境配置
下载工程(工程文件约 23118 个,下载速度较慢):
git clone [email protected]:AUTOMATIC1111/stable-diffusion-webui.git
自动配置环境(需要安装的 Python 环境较多,下载速度较慢):
cd stable-diffusion-webui
bash webui.sh # 自动安装环境
日志如下:

默认配置的 Python 环境位于:
stable-diffusion-webui/venv/bin/activate
,即使用虚拟环境
virtualenv
,即:
conda deactivate # 取消 condasource venv/bin/activate # 激活
遇到 PyTorch GPU 错误,重新安装 PyTorch 即可。
遇到问题,在虚拟环境中,手动安装一些包,注意解决 Python 包的版本冲突:
pip installeinops==0.3.0 kornia==0.6omegaconf==2.1.1 pytorch-lightning==1.4.2 torchmetrics==0.6.0 transformers==4.26.1 torch==2.0.1 torchvision==0.15.2 google-auth==2.22.0rc1 urllib3==1.26.16
pip installfacexlib==0.3.0 tb-nightly==2.14.0a20230702 sdkit==1.0.112 opencv-python==4.6.0.66 -i https://mirrors.aliyun.com/pypi/simple
# 需要安装# pip install git+https://ghproxy.com/https://github.com/mlfoundations/open_clip.git --prefer-binary
pip install open-clip-torch==2.0.2 deepspeed==0.9.5
pip install opencv-python-headless==4.8.0.74 opencv-python==4.8.0.74
默认配置的工程环境位于:
stable-diffusion-webui/repositories
,手动下载依赖工程:
cd repositories/
git clone https://ghproxy.com/https://github.com/Stability-AI/stablediffusion.git stable-diffusion-stability-ai
git clone https://ghproxy.com/https://github.com/crowsonkb/k-diffusion.git/ k-diffusion
git clone https://ghproxy.com/https://github.com/sczhou/CodeFormer.git
git clone https://ghproxy.com/https://github.com/salesforce/BLIP.git
git clone https://ghproxy.com/https://github.com/CompVis/taming-transformers
最终 5 个文件夹:
BLIP/
CodeFormer/
k-diffusion/
stable-diffusion-stability-ai/
taming-transformers/
运行 WebUI 环境 :
conda deactivate
source venv/bin/activate
python launch.py --port9301--xformers
启动成功:
Bug1: 遇到Bug “AttributeError: module ‘open_clip’ has no attribute ‘transformer’”
从源码安装
open_clip
,即可:
pip install git+https://github.com/mlfoundations/open_clip.git --prefer-binary
**Bug2: 遇到Bug “FileNotFoundError: No checkpoints found. When searching for checkpoints for Stable-diffusion” **
Stable-diffusion模型没有下载完成,即:
FileNotFoundError: No checkpoints found. When searching for checkpoints, looked at:
- file stable_diffusion/stable-diffusion-webui/model.ckpt
- directory stable_diffusion/stable-diffusion-webui/models/Stable-diffusion
Can't run without a checkpoint. Find and place a .ckpt or .safetensors file into any of those locations.
手动下载,大约4个G
cd models/Stable-diffusion
wget https://huggingface.co/runwayml/stable-diffusion-v1-5/resolve/main/v1-5-pruned-emaonly.safetensors
Bug3: 遇到Bug “No module ‘xformers’. Proceeding without it.”
已经安装 xformers,不是Bug,因为没有启动命令参数所导致,
launch.py
增加
--xformers
参数,即可:
python launch.py --port9301--listen--xformers
Bug4: 遇到Bug “Cannot locate TCMalloc”
缺少安装包
google-perftools
,安装即可。
sudoaptinstall --no-install-recommends google-perftools
**Bug5: 遇到
RuntimeError: Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check
**
原因是 PyTorch 安装异常,在 Python 中,调用
import torch
时,同样出现异常:
ImportError: cannot import name '_get_cpp_backtrace' from 'torch._C'
。
重新安装 PyTorch 即可,即先查看并卸载 PyTorch,再安装:
pip list |grep torch
pip uninstall torch torchvision
pip installtorch==2.0.1 torchvision==0.15.2
测试命令,确保 PyTorch 运行正常:
import torch
print(torch.__version__)# 2.0.1+cu117import torchvision
print(torchvision.__version__)# 0.15.2+cu117
也可使用,如下命令验证:
python -c"import torchvision; print(torchvision.__version__)"
python -c"import torch; print(torch.__version__)"
Bug6: 遇到
AttributeError: partially initialized module 'cv2' has no attribute '_registerMatType'
参考:AttributeError: partially initialized module ‘cv2’ has no attribute ‘_registerMatType’ (most likely due to a circular import)
pip install opencv-python-headless==4.8.0.74 opencv-python==4.8.0.74
2. 测试工程

Restore faces(面部修复) 需要下载模型:
Downloading: "https://github.com/xinntao/facexlib/releases/download/v0.1.0/detection_Resnet50_Final.pth" to stable-diffusion-webui/repositories/CodeFormer/weights/facelib/detection_Resnet50_Final.pth
# 下载失败,手动下载cd repositories/CodeFormer/weights/facelib/
wget https://github.com/xinntao/facexlib/releases/download/v0.1.0/detection_Resnet50_Final.pth
配置信息如下:Sampling method,Restore faces,CFG Scale
