人类作为工具
人类是AGI，因此当AI代理感到困惑时，他们当然可以被用作帮助AI代理的工具。
%pip install --upgrade --quiet langchain-community
from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_openai import ChatOpenAI, OpenAI
llm = ChatOpenAI(temperature=0.0)
math_llm = OpenAI(temperature=0.0)
tools = load_tools(
["human", "llm-math"],
llm=math_llm,
)
agent_chain = initialize_agent(
tools,

)
在上面的代码中，您可以看到该工具直接从命令行获取输入。
您可以根据需要自定义prompt_func和input_func（如下所示）。
agent_chain.run("What's my friend Eric's surname?")
# Answer with 'Zhu'
[1m> Entering new AgentExecutor chain...[0m
[32;1m[1;3mI don't know Eric's surname, so I should ask a human for guidance.
Action: Human

配置输入函数
默认情况下，HumanInputRun 工具使用 python 的 input 函数从用户那里获取输入。
你可以自定义 input_func 为你想要的任何东西。
例如，如果你想接受多行输入，你可以这样做：
def get_input() -> str:
print("Insert your text. Enter 'q' or press Ctrl-D (or Ctrl-Z on Windows) to end.")
contents = []
while True:
try:
line = input()
except EOFError:
break
if line == "q":
break
contents.append(line)
return "\n".join(contents)
# You can modify the tool when loading
tools = load_tools(["human", "ddg-search"], llm=math_llm, input_func=get_input)
# Or you can directly instantiate the tool
from langchain_community.tools import HumanInputRun
tool = HumanInputRun(input_func=get_input)
