1、Stable Diffusion是什么
- Stable Diffusion是2022年发布的深度学习文本到图像生成模型。它主要用于根据文本的描述产生详细图像，尽管它也可以应用于其他任务，如内补绘制、外补绘制，以及在提示词（英语）指导下产生图生图的翻译。
- Stable Diffusion是由德国慕尼黑大学机器视觉与学习研究小组和Runway的研究人员基于CVPR2022的一篇论文：《High-Resolution Image Synthesis with Latent Diffusion Models》，并与其他社区团队合作开发的一款开源模型。
2、深度学习环境搭建
- Anaconda下载与安装：地址
- Pycharm（IDE）下载与安装：地址
- CUDA、CuDNN下载与安装：地址
3、Stable Diffusion环境搭建（可跳过）
参考资料：地址
程序下载：地址
模型下载：地址
Github下载项目并打开运行，缺一小部分库。
打开终端，安装相关库
pytorch_lightning, omegaconf, einops
或者使用conda创建虚拟环境一键安装依赖
conda env create -f environment.yaml
conda activate ldm
下载权重
地址
在项目目录models/ldm下手动创建stable-diffusion-v1文件夹，用来存放下载好的权重文件，即需要把下载文件夹里的sd-v1-4.ckpt文件改名为model.ckpt，然后粘贴到手动创建的stable-diffusion-v1文件夹下即可
遇到报错NameError: name ‘trainer’ is not defined. Did you mean: ‘Trainer’?
根据官方wiki的教程进行修补 地址
报错2

4、Stable Diffusion WebUI环境搭建（主要）
Github下载star最多的stable-diffusion-webui项目（自带图形化包）
地址
-
使用conda创建python.3.10.6虚拟环境
conda create -n stable-webui python=3.10.6
-
激活虚拟环境
conda activate stable-webui
-
进入刚刚git clone的目录，运行webui-user.bat
等待自动安装进度条
-
根据提示增加一些git配置信息
git config –global –add safe.directory xxx/stable-diffusion-webui/repositories/taming-transformers
-
修改配置文件
增加—share解决本地localhost权限问题
-
继续执行webui-user.bat，成功启动服务
-
改一下参数，网上复制一段描述性的话，使用默认模型随机生成几张图。
5、NovelAI模型的修改与调参
模型可以在网上资源贴中下载合适的模型（.ckpt），放到models\Stable-diffusion里。
比如：地址
这里我们选择NovelAI泄漏的完整版本，用于二次元绘画
使用刚才的参数直接训练一下

- 然后是img2img，我们增加结果与原图的不同程度，得到如下
6、Chilloutmix-Ni模型
模型寻找攻略：1

-
然后我们再换用常用的3D模型生成一些图
-
最后我们使用真人模型Chilloutmix-Ni进行训练
