StableDiffusion-02 LoRA上手使用实测 尝试生成图片 使用多个LoRA 调整LoRA效果 10分钟上手 多图_lora生成图

准备工作

请你确保，你已经完成了 StableDiffusion-01 这一节的内容，可以顺利的运行SD，并且可以正常的生成图片。
本节我们就尝试使用LoRA并生成图片。

介绍 LoRA

Stable Diffusion中的LoRA（Low-Rank Adaptation，低秩自适应）是一种针对大型模型微调的技术，旨在加速模型的训练过程并显著减少模型文件的存储成本。这项技术通过冻结原有基础模型的权重层并重新计算，实现了快速的训练速度和较小的模型文件大小，从而提高了训练效率和降低了存储成本。

下载 LoRA

• Liblib模型下载：liblib官方
• Civitai模型下载：Civitai C站官方

这种左上角写：LoRA的，便是我们要下载的模型，你可以自己挑选喜欢的。

可以在网上下载到关于Lora的模型，相比于实际的模型，它会小很多。
选择 Lora选项卡：

可以看到我们需要把LoRA放到目录下，目前我下载了：五彩斑斓_1.0.safetensors
把该文件，放到上述的xxx/models/lora目录下即可

加载LoRA

重启你的服务，这个时候重新选择LoRA选项卡就可以看到了

使用 LoRA

此时点击该 Lora就会看到，Prompt提示词中多了：

<lora:新蜡笔:1>
1

此时，我们继续往提示词中添加内容即可：

<lora:新蜡笔:1>, xxxxx(你的提示词，:1表示占比，可以降低比如:0.7)

按照上一节，我们的配置，生成图片：

其他参数

保持和上一节一致即可，详见 StableDiffusion-01中的内容。

多LoRA

同理，我们下载多个 LoRA，放到指定的目录，即可看到：
