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, )
In the above code you can see the tool takes input directly from command line.
You can customize
input_func according to your need (as shown below).
agent_chain.run("What's my friend Eric's surname?") # Answer with 'Zhu'

By default, the
HumanInputRun tool uses the python
input function to get input from the user.
You can customize the input_func to be anything you’d like.
For instance, if you want to accept multi-line input, you could do the following:
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")
