记录更新版本问题，更新目前最新测试版 StableSwarmUI-0.6.4-Beta。
进入控制台界面，定位错误日志：

出现问题原因，日志已经提醒了，可能找不到对应 API 所在路径。由于个人更新版本时出现疏忽，未及时执行更新脚本 update-windows.bat。如果你是 Unix 或者 Linux 平台，请尝试执行 update-linuxmac.sh。
如果做完以上尝试，依旧存在提醒“无法向服务器发送请求，服务器是否崩溃？”。问题不大，不影响正常
Windows 平台，解决方案如下。
如果出现提醒：“无法向服务器发送请求，服务器是否崩溃”。请尝试执行更新脚本 .\StableSwarmUI-0.6.4-Beta\update-windows.bat，再次执行关闭服务器或者更新和重启服务器。
如果有你幸访问本教程，可以看到文初使用 sd_xl_base_1.0.safetensors 模型生成的图片样张。参数如下：

友情提醒 ：如果你将 seed 参数（图像种子）值设置为 -1 则会生成随机图像。如果你想强化学习，可以参考官方文档参数设置，这是一个不错的选择。
获取 StableSwarmUI：StableSwarmUI ，你需要部署 Python 环境。如果你访问 Python 官网有困难，可以从 Python中文网 获取资源。当然也可以从国内各大开源软件镜像网站获取。如果实在有困难，文末我也会给出自己上传的 Windows 平台 Python 安装包。
我个人 Python 环境，仅供参考：
1 2 PS D:\work> python -V Python 3.10 .6
Windows 平台打开 powershell 使用 expand-archive StableSwarmUI-0.6.1-Beta：
1 Expand-Archive .\StableSwarmUI-0 .6.1 -Beta .zip -DestinationPath E:\AI\
进入 StableSwarmUI 根目录：
1 cd E:\AI\StableSwarmUI-0 .6.1 -Beta \
让我们一起愉快的开启 StableSwarmUI 体验之旅吧，在这之前，再次友情提醒安装好 Python 环境哟。
StableSwarmUI 安装与启动 启动 StableSwarmUI 之前我想介绍一下，个人硬件环境（笔电）。不算太新，不算太老，将将能玩（学习）：
CPU：R7-7735H（实际上是 R7-6800H的马甲U，苏妈挤了多少次牙膏了，升级命名鬼才）。8 个纯大核 u，平时也够用了。
显卡(GPU)：NVIDIA GeForce RTX 4060 Laptop GPU, 8.00 GiB
上了独立显卡，这种搭配，AMD 强劲的核显显得有点浪费了。
大学新生开学季，怎么套路换电脑？新思路，老爸啊，你儿子想学 Ai，需要高配一丢丢的 N 卡作为生产力。千万别说是我教的 ，问就是生产力需要。
有点跑题了，继续 StableSwarmUI 介绍， 目前处于 Beta 版本
A Modular Stable Diffusion Web-User-Interface, with an emphasis on making powertools easily accessible, high performance, and extensibility.
安装与启动，Windows 平台执行 launch-windows.bat 脚本，安装过程可能比较缓慢，也许你需要科学上网。

初次安装 ，从官方渠道获取比较缓慢，优先访问 https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors，看到报错或者警告信息是正常状态。在国内无法访问进去，可以前往第三方网站或者社区，比如魔搭社区获取他人上传的模型数据。
sd_xl_base_1.0 模型获取 魔搭社区，获取 sd_xl_base_1.0.safetensors
如果你使用 git 获取，默认你已经部署并配置好 Git 环境，可以直接获取完整模型训练仓库 git clone https://www.modelscope.cn/AI-ModelScope/stable-diffusion-xl-base-1.0.git。当然，你也可以点击文件 sd_xl_base_1.0.safetensors 直接下载。如果急需体验，个人推荐直接下载模型文件。完整模型仓库所占空间较大，存在版本库迭代，每个作者提交同步的内容有所不同。
如果本地没有模型数据 ，需要获取别人培养的模型数据，复制到 StableSwarmUI 指定的 \StableSwarmUI-0.6.1-Beta\Models\Stable-Diffusion\OfficialStableDiffusion 目录。
传入模型数据后，进入 web UI 界面点击模型，刷新即可看到模型。个人建议，最好还是在服务器功能模块选择服务器信息功能，点击关闭服务（Shutdown Server），然后再次执行 launch-windows.bat 启动 web 应用程序。
本地启动完成后，会自动跳转到默认设置浏览器，访问 http://localhost:7801
