高清人像生成 Stable Diffusion on Colab
本文介绍由基于Stable-diffusion的Chilloutmix模型（以及最新的ControlNet）生成高清真实人像的方法及Demo。
- 利用免费的Google Colab的在线环境创建Stable Diffusion WebUI，可以免去配置环境的麻烦。
身处内地的朋友：由于Colab是Google的服务，如果你在内地，需要一点上网的技巧（个人用的Renzhe.Cloud，还比较稳）
1. 可以一键运行的Google Colab环境
-
Chilloutmix模型（通用的人物生成）：Colab运行环境
-
Korean Doll Likeness LoRA模型（主要为韩国女生风）：Colab运行环境、Civitai效果图
-
图生图ControlNet模型（主要为以图生图）： Colab运行环境
2. YouTube小白教程
