Databricks Databricks-Generative-AI-Engineer-Associate Question Answer

A Generative AI Engineer is testing a simple prompt template in LangChain using the code below, but is getting an error:

Python

from langchain.chains import LLMChain

from langchain_community.llms import OpenAI

from langchain_core.prompts import PromptTemplate

prompt_template = " Tell me a {adjective} joke "

prompt = PromptTemplate(input_variables=[ " adjective " ], template=prompt_template)

# ... (Error-prone section)

Assuming the API key was properly defined, what change does the Generative AI Engineer need to make to fix their chain?

(Incorrect structure)

prompt_template = " Tell me a {adjective} joke "

prompt = PromptTemplate(input_variables=[ " adjective " ], template=prompt_template)

llm = OpenAI()

llm_chain = LLMChain(prompt=prompt, llm=llm)

llm_chain.generate([{ " adjective " : " funny " }])

(Incorrect structure)
