Stable Diffusion WebUI

1. Define

    # 安装

2. Register

from launcher import StableDiffusion2Launcher
from src.utils.cblauncher import CosyVoiceLauncher, GptSovitsLauncher, IndexTTSLauncher, IOPaintLauncher, LauncherProvider, StableDiffusionLauncher

class Launcher:

    @staticmethod

    ...

if __name__ == "__main__":
    project = "stable_diffusion_webui2"
    python = "3.10"

        "host": "0.0.0.0",
        "port": 9000,
        "share": False,
    }
    # 创建启动器
    launcher = Launcher.builder(project, **kwargs)
    # 执行流程
    launcher.create()
    launcher.install()
    launcher.start().wait()
