You.com 搜索

you.com API 是一套工具，旨在帮助开发者将LLMs的输出与最新、最准确、最相关的信息联系起来，这些信息可能没有包含在他们的训练数据集中。

设置​

该工具位于 langchain-community 包中。 您还需要设置您的 you.com API 密钥。

%pip install --upgrade --quiet langchain-community
import os
os.environ["YDC_API_KEY"] = ""
# 用于链接部分
os.environ["OPENAI_API_KEY"] = ""
## 或者从.env文件中加载YDC_API_KEY
# !pip install --quiet -U python-dotenv
# import dotenv
# dotenv.load_dotenv()

设置 LangSmith 也是有帮助的，以获得最佳的可观察性。

# os.environ["LANGCHAIN_TRACING_V2"] = "true"
# os.environ["LANGCHAIN_API_KEY"] = getpass.getpass()

我们在这里展示如何将其作为[代理](/docs/tutorials/agents)的一部分。我们使用 OpenAI Functions 代理，因此需要设置并安装所需的依赖项。我们还将使用[LangSmith Hub](https://smith.langchain.com/hub)来获取提示，因此需要安装该工具。
```python
# 你需要一个模型来在链中使用
