MLflow 追踪集成

MLflow 跟踪与一系列常用的生成式 AI 库和框架集成，为所有库和框架提供 单行自动跟踪 体验。 这样，就可以在最少的设置下立即获得 GenAI 应用程序的可观测性。

自动跟踪根据特定库或 SDK 的实现方式捕获应用程序逻辑和中间步骤，例如 LLM 调用、工具使用情况和代理交互。

若要深入了解自动跟踪的工作原理、其先决条件以及将其与手动跟踪相结合的示例，请参阅主要的 自动跟踪 指南。 下面的快速示例突出显示了一些顶级集成。 本部分各自页面上提供了每个受支持的库的详细指南，涵盖先决条件、高级示例和特定行为。

启用多个自动跟踪集成

由于 GenAI 应用程序通常合并多个库，因此 MLflow 跟踪允许同时为多个集成启用自动跟踪，从而提供统一的跟踪体验。

例如，若要启用 LangChain 和直接 OpenAI 跟踪，

import mlflow

# Enable MLflow Tracing for both LangChain and OpenAI
mlflow.langchain.autolog()
mlflow.openai.autolog()

# Your code using both LangChain and OpenAI directly...
# ... an example can be found on the Automatic Tracing page ...

MLflow 将生成一个统一的跟踪，该跟踪结合了 LangChain 和直接 OpenAI LLM 调用中的步骤，使你能够检查完整的流。 可以在 “自动跟踪 ”页上找到更多合并集成示例。

禁用自动跟踪

可以通过调用 mlflow.<library>.autolog(disable=True)来禁用任何特定库的自动跟踪。 若要一次性禁用所有自动记录集成，请使用 mlflow.autolog(disable=True)。

import mlflow

# Disable for a specific library
mlflow.openai.autolog(disable=True)

# Disable all autologging
mlflow.autolog(disable=True)
