前言

• 因为使用Stable Diffusion进行AI绘图需要GPU，这让其应用得到了限制
• 本文介绍如何在Kaggle中部署Stable Diffusion，并使用免费的P100 GPU进行推理（每周可免费使用30小时），部署好后可以在任意移动端使用。
• 本项目在stable-diffusion-webui-kaggle基础上进行改进，原作者Github项目地址
• 欢迎大家Copy and Edit我的kaggle notebook，项目地址。效果展示
  

使用教程

• 首先需要注册Kaggle账号，注册过程中可能需要科学上网，这里不展开教程了，请大家查找其他教程解决
• 新建notebook，并将下列代码放入其中

• 这里我将原始的anything-v4.5-vae-swapped模型删除了，下载了GuoFeng3主干模型和KoreanDollLikenessLora模型。
• 主干模型相当于图片的主调，比如GuoFeng3模型就是中国华丽古风风格，也可以说是一个古风游戏角色。
• Lora模型相当于微调主干模型的某一部分，KoreanDollLikeness就是主要调整面部结构，更多具体的说明可以自行查询。
• 粘贴好上面代码以后运行代码块，大约需要5~10分钟时间，中间可能会有警告和错误，不需要管，只要运行没有终止就可以（截止2023年5月24日上述代码可用）。
• 部署好后会出现如下链接：
