本文分享自华为云社区《重磅！【支持中文】stable-diffusion-3安装部署教程-SD3 来了》，作者：码上开花_Lancer。
正如承诺的那样，Stability AI在6月12日正式开源了Stable Diffusion 3（Medium版本）！不愧是AI生图领域的“开源英雄”。最近一段时间，正当所有人都在为OpenAI发布Sora狂欢时，Stability AI更是推出了Stable Diffusion 3的技术报告。这两项技术不约而同都采用了Diffusion Transformer的架构设计。
值得注意的是，Stable Diffusion 3的强大性能其实并不仅限于Diffusion Transformer在架构上所带来的增益，其在提示词、图像质量、文字拼写方面的能力都得到了极大的提升。那么究竟是什么让Stable Diffusion 3如此强大？今天我们就从Stable Diffusion 3的技术报告中解读stable diffusion 3强大背后的技术原理。
接下来就讲讲，怎么在本地部署最新的Stable Diffusion 3，大致分为以下几步（开始操作前，请确保你有“畅通”的网络）：
一、前期准备
1.登录华为云官方账号：
点击右上角“控制台”，搜索栏输入“ModelArts”
点击“开发环境”-“notebook”,“创建”：
进入创建notebook，名称“notebook-LangChain”,选择GPU规格，“GPU: 1*T4(16GB)|CPU: 8核 32GB”，点击“立即创建”，磁盘规格选择“50G”,点击“创建”
点击返回“任务中心”，点击notebook进入
以上步骤是从ModelArts上自己创建notebook，也可以直接点击案例进入体验--stable-diffusion-3重磅来袭。
二、下载模型
[Stable Diffusion 3 Medium](https://stability.ai/news/stable-diffusion-3-medium) 是一种多模态扩散转换器 (MMDiT) 文本到图像模型，其特点是在图像质量、排版、复杂提示理解和资源效率方面大大提高了性能。有关更多技术细节，请参阅[研究报告](https://stability.ai/news/stable-diffusion-3-research-paper)。
🔹 本案例需使用 Pytorch-2.0.1 GPU-V100 及以上规格运行
🔹 点击Run in ModelArts，将会进入到ModelArts CodeLab中，这时需要你登录华为云账号，如果没有账号，则需要注册一个，且要进行实名认证，参考[《如何创建华为云账号并且实名认证》](https://bbs.huaweicloud.com/blogs/427460) 即可完成账号注册和实名认证。 登录之后，等待片刻，即可进入到CodeLab的运行环境
🔹 出现 Out Of Memory ，请检查是否为您的参数配置过高导致，修改参数配置，重启kernel或更换更高规格资源进行规避❗❗❗
首先切换kernrl，
1. 下载代码和模型
