人类AGI工具
人类具有AGI，因此当AI代理处于困惑状态时，它们可以作为工具来帮助。
from langchain.chat_models import ChatOpenAI
from langchain.llms import OpenAI
from langchain.agents import load_tools, initialize_agent
from langchain.agents import AgentType
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,
llm,
agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
verbose=True,
)
在上面的代码中，您可以看到工具直接从命令行接收输入。您可以根据需要自定义 prompt_func 和 input_func（如下所示)。
agent_chain.run("When's my friend Eric's surname?")
# Answer with 'Zhu'
> Entering new AgentExecutor chain...
我不知道Eric的姓氏，所以我需要向人类寻求帮助。
行动: 人类
行动输入："Eric的姓氏是什么？"
Eric的姓氏是什么？
观察结果: Zhu
想法：我现在知道Eric的姓氏是Zhu。
最终答案：Eric的姓氏是Zhu。
> 完成链式结构。
"Eric的姓氏是Zhu。"
配置输入函数
默认情况下，HumanInputRun工具使用Python的input函数从用户处获取输入。您可以自定义input_func。例如，如果您想接受多行输入，则可以执行以下操作：
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.tools import HumanInputRun
tool = HumanInputRun(input_func=get_input)
agent_chain = initialize_agent(
tools,
llm,
agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
verbose=True,
)
agent_chain.run("I need help attributing a quote")
> Entering new AgentExecutor chain...
