先记录了一些坑和解决办法，后面再更新搭建步骤，争取尝试做个一键安装脚本试试

• 不行，太激动了，总算可以跑了。最开始安装好之后，加载的 v1_5 模型，可以跑没问题，但后面更换了 v2_1 模型后跑出来始终是报错

  modules.devices.NansException: A tensor with all NaNs was produced in Unet. This could be either because there's not enough precision to represent the picture, or because your video card does not support half type. Try setting the "Upcast cross attention layer to float32" option in Settings > Stable Diffusion or using the --no-half commandline argument to fix this. Use --disable-nan-check commandline argument to disable this check.

  看不太懂，是不支持半精度浮点数的意思吗？加上 --no-half 参数启动直接 gg。参考了 Github 上的讨论链接。先是下了个 toolkit 工具 然后修复了下模型，最开始还是不行，我也不知道是不是没加载好的原因，但我后面又添加了 --xformers 启动参数，查了下，这是个优化内存和显存的工具，确实有用，我的内存直接降了 3 个多G，显存降了进 2 个G，这优化确实给力。然后就加载修复好的模型就可以跑了

• 尝试了下，官方的 model 用着。。。一言难尽。但网上的模型真的好美，比如下面的描述词
