关于 SD异常 NansException: A tensor with all NaNs was produced in Unet. 显卡1660ti 6GB-526互联

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.

装好 SD webui 最新版后，重装xformers

办法是直接添加启动参数：

--reinstall-xformers --xformers
