Stable Diffusion安装 Stable Diffusion简介stable diffusion是一种能够根据文本描述生成图像的深度学习模型，于2022年发布，由创业公司Stability AI开发和维护。它可以用来生成各种风格和主题的图像，也可以用来修改已有的图像或者填补低分辨率或者缺失细节的图像。它的代码和模型权重都是公开的，可以在大多数配备了至少8GB显存的GPU上运行。stable diffusion是一种潜在扩散模型（latent diffusion model），这是一种深度生成神经网络。它的原理是通过不断地去噪随机噪声，直到达到设定的步数，从而生成目标图像。在这个过程中，它会受到一个文本编码器（text encoder）的指导，这个编码器可以将文本描述转换成图像的语义信息。stable diffusion有三个主要部分：变分自编码器（variational autoencoder），U-Net和一个可选的文本编码器。变分自编码器可以将图像从像素空间压缩到一个更小维度的潜在空间，捕捉图像的更本质的语义含义。U-Net是一种卷积神经网络，可以将潜在空间中的向量还原成图像。文本编码器可以根据文本描述生成一个向量，作为潜在空间中的先验分布，引导U-Net生成符合文本描述的图像。要使用stable diffusion生成图像，你需要给它一个文本描述，例如“一只猫坐在沙发上”或者“一幅风景画”。你也可以给它一些风格或者细节上的指示，例如“卡通风格”或者“有雪山和湖泊”。stable diffusion会根据你给出的文本描述，在潜在空间中寻找一个最合适的向量，并用U-Net将它转换成图像。你可以看到生成过程中每一步的结果，也可以调整参数来改变生成效果。stable diffusion是一个非常强大和灵活的图像生成模型，它可以让你用语言来创造你想象中的任何图像。你可以用它来做艺术创作、设计、教育、娱乐等各种用途。如果你想了解更多关于stable diffusion的信息，你可以访问它的官方网站或者查看它的源代码。硬件配置硬件配置操作系统windows11CPUi5-10400F内存64G显卡RTX 2070（8G）最低显卡2G显卡的大小对跑图的速度影响较大部署采用秋葉大佬的整合包v4秋葉大佬官方链接：https://pan.baidu.com/s/1_ibEk2OpKHxmEg4AnFOpSA 提取码 b145 秋葉大佬B站地址快速开始使用 → https://www.bilibili.com/read/cv22661198 新手最全教程 → https://www.bilibili.com/read/cv22159609 开始安装 下载下来这几个包如图解压sd-webui-aki-v4.1安装环境依赖启动器运行依赖-dotnet-6.0.11.exe安装完成后打开sd-webui-aki-v4sd-webui-aki-v4 目录打开用户协议进行编辑，输入我已阅读并同意用户协议后保存退出点击A启动器.exe运行软件等待检测完成后进入界面启动器设置打开启动器，进入界面2.点击设置，进行配置3.点击高级选项进行配置4.查看自己显卡信息方法一：快捷按键 win+r 输入cmd 方法二：点击win图标，选择windows终端，输入nvidia-smi如图5.高级选择——环境维护配置6.下载一个模型如图7.进入高级模式点击一键启动8.第一次启动会比较慢，等待出现127.0.0.1:7860,启动成功 9.浏览器输入地址，进入sdStable Diffusion安装结束/system/bin/device_config set_sync_disabled_for_tests persistent; /system/bin/device_config put activity_manager max_phantom_processes 2147483647Y08C53C65EF898E4FA3ECE35EBE456F5 -
