LangChain - Agents

This code snippet throws an error:

agent = OpenAIFunctionsAgent.from_llm_and_functions(model, functions=["not_a_function"])
response = agent.invoke("Hello")

What is the error and how to fix it?

AImportError because OpenAIFunctionsAgent is not imported; fix by importing

BValueError because function list is empty; fix by adding functions

CTypeError because strings are not callable; fix by passing actual functions

DNo error; code runs fine

Step-by-Step Solution

Solution:

Step 1: Identify cause of error
Passing a string instead of a callable function causes TypeError when agent tries to call it.
Step 2: Fix the error
Replace string with actual function objects in the functions list.
Final Answer:
TypeError because strings are not callable; fix by passing actual functions -> Option C
Quick Check:
Functions must be callable, not strings = TypeError because strings are not callable; fix by passing actual functions [OK]

Quick Trick: Functions list must contain callable functions, not strings [OK]
