How can I resolve the 'langchain.verbose' AttributeError in my chatbot code?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm trying to create a simple word-meaning chatbot using LangChain, but I'm encountering the following error when I run my code:

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

Here is my code:

PYTHON
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)

I suspect the error might be caused by a naming conflict or a circular import issue. I've read that naming your script the same as a module (like langchain.py) can often lead to this type of error. What steps can I take to resolve this?

Any guidance would be greatly appreciated.

The error you're seeing is usually caused by a circular import or a naming conflict. A common issue is naming your script (or another file in the same directory) with the same name as one of the libraries you’re importing (such as langchain). This can lead Python to import your local file instead of the actual library, causing the error.

Here’s what you can do to fix it:

Rename Your File:
Make sure your script isn't named langchain.py (or something similar). Rename it to something like my_chatbot.py.
Remove Compiled Files:
After renaming, delete any pycache directories or .pyc files in your project directory to ensure Python isn’t using cached imports:
```
BASH
find . -type d -name "__pycache__" -exec rm -r {} +
```
Check Your Imports:
Ensure that there are no circular import issues in your project. The provided code looks fine in isolation once the naming conflict is resolved.

After these changes, run your script again. Your chatbot setup should work as expected without the AttributeError.

Let me know if you encounter any further issues!

You are getting this error because you have a file named langchain.py

Please change your file name to some other name.

Also, please refrain from naming your file names to module names, keywords, etc.
