这篇帖子已经有1个月了，在Langchain年里基本上相当于1年。很多事情都发生了变化。请尝试更新到最新版本：

= to this
langchain==0.0.134
from langchain.agents import load_tools
tool_names = [...]
llm = ...
tools = load_tools(tool_names, llm=llm)

我曾经遇到一个类似的问题，尝试通过 `pip install langchain[all]` 安装 langchain 以及所有集成。

这样安装后，我得到了一个较旧的 langchain 版本，甚至无法导入 `langchain.agents.load_tools` 模块，因为它并不存在。

后来，我通过运行 `pip install langchain --upgrade` 来升级到最新版本的 langchain，问题得到了解决。

随后，我成功按预期导入了它，使用了 `from langchain.agents import load_tools`。

I had a similar issue installing langchain with all integrations via `pip install langchain[all]`.

This installed some older langchain version and I could not even import the module `langchain.agents.load_tools` since it did not exist.

I just fixed it with a langchain upgrade to the latest version using `pip install langchain --upgrade`.

After that, I was able to import it with `from langchain.agents import load_tools` as expected.
