多环境适配指南

HippoRAG通过统一接口设计支持灵活切换推理后端,主要操作如下:

  • 云端OpenAI服务::
    1. set upexport OPENAI_API_KEY=sk-xxx
    2. 初始化时指定llm_model_name='gpt-4o-mini'
  • 本地vLLM部署::
    1. Starting servicesvllm serve meta-llama/Llama-3.3-70B-Instruct
    2. configurellm_base_url='http://localhost:8000/v1'
  • hybrid model: By--llm_namecap (a poem)--llm_base_url参数动态选择

关键调试技巧::

  • 测试连接性:运行hipporag.check_llm_connection()
  • 性能调优:
    • OpenAI模型建议添加--max_tokens 512限制响应长度
    • vLLM模型调整--gpu-memory-utilization 0.9提高吞吐量
