如何实现NodeRAG与本地大语言模型的高效集成?

2025-08-24 1.1 K

集成本地LLM需要分步骤配置:

  1. 模型准备阶段::
    – 确认模型格式为GGUF或HuggingFace标准格式
    – 推荐最低配置:7B参数模型+16GB内存
  2. Configuration file modification::
    编辑config.yaml的llm_module部分:
    llm_module:
    local_path: "/path/to/your/model"
    model_type: "llama" # or "gpt", "mistral"等
    context_window: 4096
    temperature: 0.65
  3. test connection::
    Run commandpython -m NodeRAG.llm_test验证模型加载是否正常
  4. performance optimization::
    – 启用uv加速:uv pip install llama-cpp-python
    – 在GPU机器上添加CMAKE_ARGS="-DLLAMA_CUBLAS=on"environment variable

注意:首次运行会较慢(需要加载模型权重),后续查询会缓存中间结果提升速度。如果响应延迟>5秒,建议降低max_tokens参数或切换轻量级模型。
