版本v2.5.41

Stable Diffusion 图像生成工具是一种基于深度学习的技术，可以从随机噪声中生成高质量的图像，利用 Diffusion Probabilistic Models 的概率模型，逐步地将噪声转化为目标图像，同时保持图像的稳定性和多样性。Stable Diffusion 图像生成工具的优点是，不需要预先训练一个生成器网络，而是可以直接从数据分布中采样图像，也可以适应不同的图像域，例如人脸、动物、风景等。Stable Diffusion 图像生成工具是一种创新的图像合成技术，可以为各种应用场景提供高效和实用的解决方案。

安装网页：https://stable-diffusion-ui.github.io/docs/installation/
GitHub：https://github.com/AUTOMATIC1111/stable-diffusion-webui

在系统中，需要包含 conda 环境，不需要额外创建，在运行过程中，在文件夹中，就会创建默认的环境。

软件下载路径：

下载 Easy-Diffusion-Linux 压缩包。
解压压缩包，cd easy-diffusion。
运行 bash start.sh。

### Linux

1. [**Download** for Linux](https://github.com/cmdr2/stable-diffusion-ui/releases/download/v2.5.24/Easy-Diffusion-Linux.zip)
2. Extract:
   - Extract the file with your favourite file manager, or use `unzip Easy-Diffusion-Linux.zip` in a terminal.
   - After extracting the .zip file, please open a terminal, and go to the `easy-diffusion` directory.
3. Run:
   - In the terminal, run `./start.sh` (or `bash start.sh`)

This will automatically install Easy Diffusion, set it up, and start the interface. No additional steps are needed.

执行 bash start.sh ，开始安装环境，遇到 Git 工程无法下载，手动下载即可。需要注意的点，如下：

因国内网速问题，部分包无法安装，需要手动安装，参考Bug 2~5。
GitHub 工程无法下载，也需要手动下载，建议使用 git ssh 方式。
GitHub 模型无法下载，手动下载之后，放入相应的文件夹，即 easy-diffusion/models，具体参考源码。

遇到 Bug，则需要重新安装 Python 包，先激活 Conda 环境 conda activate easy-diffusion/installer_files/env ，再安装相应的 Python 包，即可。

conda activate stable_diffusion/easy-diffusion/installer_files/env

pip install facexlib==0.3.0 tb-nightly==2.14.0a20230702 sdkit==1.0.112 xformers==0.0.20 -i https://mirrors.aliyun.com/pypi/simple

模型手动下载地址，参考 stable-diffusion-webui 源码：

Bug1: 遇到 Bug “Failed to connect to github.com port 443: Connection timed out”

即：

fatal: unable to access 'https://github.com/cmdr2/stable-diffusion-ui.git/': Failed to connect to github.com port 443: Connection timed out

EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

ERROR: git clone failed

Error downloading Stable Diffusion UI. Sorry about that, please try to:
 1. Run this installer again.
 2. If that doesn't fix it, please try the common troubleshooting steps at https://github.com/cmdr2/stable-diffusion-ui/wiki/Troubleshooting
 3. If those steps don't help, please copy *all* the error messages in this window, and ask the community at https://discord.com/invite/u9yhsFmEkB
 4. If that doesn't solve the problem, please file an issue at https://github.com/cmdr2/stable-diffusion-ui/issues

Thanks!

位于：on_env_start.sh 脚本，进入 easy-diffusion/scripts 文件夹，手动下载 https://github.com/cmdr2/stable-diffusion-ui.git/，即可，推荐使用 git ssh 下载

git clone [email protected]:easydiffusion/easydiffusion.git

Bug2: 遇到 Bug “No module named facexlib”

这个问题，在安装sdkit时，也会遇到，即：

  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [17 lines of output]
      Traceback (most recent call last):
        File "/tmp/pip-install-ftrx1th1/gfpgan_051d13278c764431bd5491fa888528ee/setup.py", line 48, in get_hash
          from facexlib.version import __version__
      ModuleNotFoundError: No module named 'facexlib'
...

直接手动安装即可，即pip install facexlib==0.3.0

Bug3: 遇到 Bug “gfpgan 1.3.8 depends on tb-nightly”

切换安装源至 aliyun 即可：

pip install tb-nightly==2.14.0a20230702 -i https://mirrors.aliyun.com/pypi/simple

Bug4：遇到 Bug “No module named sdkit”

这个是关键安装包，即

  File "easy-diffusion/ui/easydiffusion/utils/save_utils.py", line 10, in <module>
    from sdkit.utils import save_dicts, save_images
ModuleNotFoundError: No module named 'sdkit'

先安装facexlib和tb-nightly，再直接 pip install sdkit==1.0.112 ，即可。

Bug5: 遇到 Bug “No module ‘xformers’. Proceeding without it.”

即

No module 'xformers'. Proceeding without it.

切换安装源至 aliyun 即可：

pip install xformers==0.0.20 -i https://mirrors.aliyun.com/pypi/simple

运行成功，日志如下：
