4. 生成拜年图

本节将为大家演示如何使用imAgine绘图方案生成新春贺年图，以下呈现了几张效果图，祝大家龙年大吉！

Stable Diffusion (SD)是2022年发布的开源的文生图模型，通用性强，但无法满足对细节和特定内容的绘图需求，因此人们通常会对官方SD模型进行微调来得到可以应用于特定领域的定制模型。常见的SD微调技术包括Dreambooth ，LoRA ，Textual Inversion （也称为 Embedding）和Hypernetworks 等，几种技术的对比可参考此博客 。为了方便您使用，本次实验涉及到的模型均已预装入专用的AMI中。

4.1 实验环境准备

实验开始前，请确保您已完成以下事项：

• 已按照0.简介与前提条件申请了加速计算型实例资源

• 已按照1.订阅和部署解决方案订阅并部署了imAgine绘图解决方案。
