没有名为verbose[closed]的属性

这是我的代码:

from langchain_core.prompts import ChatPromptTemplate
from langchain_ollama import ChatOllama

llm = ChatOllama(
    model = 'llama3.2',
    temperature = 0
)

chat_template = ChatPromptTemplate.from_messages(
    [
        ('system', "you have to give two line definition of the word given by user"),
        ('human', 'the word is {user_input}')
    ]
)

message = chat_template.format_messages(user_input = 'backlog')
print(message)

response = llm.invoke(message)
print(message)

显示属性错误:

AttributeError: partially initialized module 'langchain' has no attribute 'verbose' (most likely due to a circular import)

我该怎么解决这个问题? 我试图使用langchain创建基本的单词含义聊天机器人。
