在第一次运行StableDiffussion的webui.bat时，在installing requirements这里停留了半小时无反应，就把cmd关掉了。再打开webui.bat, 未跳出http地址或者下载库。最后通过运行 python D:\SD\sd-webui-aki-v4.8\sd-webui-aki-v4.8\webui.py，继续进入下载依赖库的流程。
然后遇到"No module 'xformers'. Proceeding without it. "的报错，是通过在webui-user.bat里设置'set COMMANDLINE_ARGS=--xformers'解决
官方ComfyUI的V0.2.7版本的包使用xformers 的方法:
https://www.reddit.com/r/comfyui/comments/1gnl352/comfyui_starting_log_errors_please_help/
即在用包内置的python.exe运行以下命令:
D:\ComfyUI_windows_portable_nvidia\ComfyUI_windows_portable\python_embeded>python.exe -s -m pip install -U xformers --index-url https://download.pytorch.org/whl/cu124

个人理解
按我的理解，
文生图的话，基本流程是: 图像先通过CLIP(Contrastive Language-Image Pre-training 对比语言-图像预训练）把文字编码成潜在空间，然后传给Sampler。Sample根据模型Model和随机生成的噪声，对此潜空间推理，得到latent格式的图像，然后通过VAE Decoder解码成常规图片格式的文件
即如下图所示:
文生图.png
图生图的话，基本流程是在文生图的基础上，再加入Load image和VAE Encode两个节点。即如下图所示
术语解释:
CFG：表示对提示词的忠诚度。值越大，输出的图像越接近提示词的描述，但可能会降低图像质量，显得不真实或者不自然。0表示忽略提示词。一般在6~8之间。模型也会有推荐值，比如量化表的Flux 模型就是1.0
降噪(denoise): 表示去噪过程中不保留原图的程度 1.0 表示完全重新生成; 较低的值会保留更多原始图像的特征，太低的话会导致画面模糊。图生图建议值为0.5-0.7。文生图的话，填1就可以了。
