1. 调试
如果您正在使用LLMs构建，那么某个时刻会出现问题，您需要进行调试。模型调用将失败，或者模型输出格式不正确，或者存在一些嵌套的模型调用，不清楚在哪个位置创建了不正确的输出。
以下是几种不同的工具和功能，可用于帮助调试。
2. 跟踪 Tracing
具有类似LangSmith和WandB的跟踪能力的平台是调试的最全面解决方案。这些平台不仅可以轻松记录和可视化LLM应用程序，还可以积极地进行调试、测试和改进。
对于任何构建生产级LLM应用程序的人，我们强烈建议使用这样的平台。
3. set_debug设置调试和set_verbose设置详细
如果您在Jupyter笔记本中进行原型设计或运行Python脚本，打印出链式运行的中间步骤可能会有所帮助。
有许多方法可以以不同程度的详细程度启用打印。
假设我们有一个简单的代理，并希望可视化它所采取的操作和接收到的工具输出。 没有任何调试，这就是我们所看到的：
from langchain.agents import AgentType, initialize_agent, load_tools
from langchain.chat_models import ChatOpenAI
llm = ChatOpenAI(model_name="gpt-4", temperature=0)
tools = load_tools(["ddg-search", "llm-math"], llm=llm)
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)
agent.run("Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?")
输出
'The director of the 2023 film Oppenheimer is Christopher Nolan and he is approximately 19345 days old in 2023.'
3.1 set_debug(True)设置调试为True
设置全局调试标志将导致所有具有回调支持的LangChain组件（链、模型、代理、工具、检索器）打印它们接收的输入和生成的输出。这是最详细的设置，并将完全记录原始输入和输出。
