Bases: BaseLlamaPack
Arize-Phoenix LlamaPack 演示了如何使用追踪来检测您的 LlamaIndex 查询引擎。它在后台启动 Phoenix，在一个输入的节点列表上构建索引，并实例化和检测该索引上的查询引擎，以便每次查询的追踪数据发送到 Phoenix。
注意：使用此 LlamaPack 需要通过 OPENAI_API_KEY 环境变量设置您的 OpenAI API 密钥。

The Arize-Phoenix LlamaPack show how to instrument your LlamaIndex query
engine with tracing. It launches Phoenix in the background, builds an index
over an input list of nodes, and instantiates and instruments a query engine
over that index so that trace data from each query is sent to Phoenix.
Note: Using this LlamaPack requires that your OpenAI API key is set via the
OPENAI_API_KEY environment variable.
