模型大小：6~7GB
推荐配置：6GB或以上显存的NVIDIA显卡,1GB/s或以上的硬盘读写速度。

用法

首先下载ConfyUI(windows用户直接下载整合包)和模型,解压后把模型放入主目录中的ComfyUI➡models➡checkpoints 文件夹中,例如：G:\Project\Stable Diffusion1.0\ComfyUI_windows_portable\ComfyUI\models\checkpoints
英伟达显卡运行run_nvidia_gpu.bat,没有可以运行run_cpu.bat(显存不足自动开启低显存模式),稍等片刻自动打开网页程序

可以看到图形界面有正面提示词和负面提示词,可以运行默认的提示词先看看效果,点击Queue Prompt生成,第一次出图一般都是下面这张：

注意第一次使用要先加载模型,加载速度和硬盘读写速度以及设备性能有关。如果配置较低请耐心等待，并没有卡住,只是比较慢罢了。
在Empty Latent Image 下可以修改生成的图像大小,最大像素为1024×1024，默认512×512
在Ksample下可以修改步数和CFG值(classifier-free guidance scale),并不是越高越好,可自行摸索。
图像生成后自动保存到ComfyUI下的output文件夹中,也可以右键图像,自定义存储位置。
想要生成复杂的图形一定要多加一些提示词,可以自行谷歌相关模板。

视频教程

视频的后半段为stable-diffusion-webui的安装教程,配置要求更高,显存≥12GB推荐试一试,可以安装额外的插件,更为方便。
