如何实现Nunchaku与现有ComfyUI工作流的无缝集成?

2025-08-23 513

整合操作指南

实现ComfyUI与Nunchaku的深度集成需要完成以下关键步骤:

  • Plug-in Installation::
    • 通过ComfyUI Manager安装官方插件:comfy node registry-install ComfyUI-nunchaku
    • 或手动克隆仓库到custom_nodescatalogs
  • 模型路径配置::
    • 标准化目录结构:
      • models/text_encoders/存放clip_l.safetensors
      • models/vae/存放ae.safetensors
    • Using Environment VariablesNUNCHAKU_MODEL_ROOT指定全局路径
  • 工作流迁移::
    • 导入示例JSON工作流(如nunchaku-flux.1-dev-pulid.json)
    • 替换原有KSampler节点为NunchakuQuantSampler
    • 在CLIPTextEncode节点前插入T5-4bit量化选项

性能优化技巧:
• 启用t5_min_length=512提升长文本理解质量
• 设置end_timestep=0.7可加速图像编辑流程
• 通过PuLID节点的strength=0.3平衡细节保留与编辑强度
