ModuleNotFoundError Traceback (most recent call last) Cell In[5], line 3 1 from langchain.chains import LLMChain 2 from langchain.chains.question_answering import load_qa_chain ----> 3 from langchain.chains.chat_index.prompts import CONDENSE_QUESTION_PROMPT

I also encountered this problem

[ghost]

can you try this from langchain.chains.conversational_retrieval.prompts import CONDENSE_QUESTION_PROMPT

[Wzy210121]

Thanks! got it from the default config "ConversationalRetrievalChain.from_llm()"

I get a similar issue:

After installing pip install langchain[all]

These two imports don't work: from langchain.chains.question_answering import load_qa_chain from langchain.callbacks import get_openai_callback

Traceback (most recent call last): File "C:\Users\valte\PycharmProjects\ChatWithPDF\main.py", line 1, in from langchain.chains.question_answering import load_qa_chain ModuleNotFoundError: No module named 'langchain.chains.question_answering'

Any advice would be much appreciated.

EDIT:

I managed to get around this in a hacky way by installing some packages with pip and langchain with conda. (other ways resulted in something not working)

I noticed it today. I have an exact problem with the above, I can't import these two anymore: from langchain.chains.question_answering import load_qa_chain from langchain.callbacks import get_openai_callback

I've tried what is suggested above and installed langchain with conda with this command: conda install -c conda-forge langchain

still not working. Any suggestions? @ValtersJZ do you have any tips? since you've fixed the exact same problem :D

I faced the same issue today. Corrected it by updating the python version to 3.11.2

[jawndiego]

tried to upgrade python to 3.11.2 no luck. still encountering:

from langchain.chains.question_answering import load_qa_chain

[ataguru]

This is probably due to some conflict in other packages in your environment. I've set up a fresh environment from scratch and it worked again.

I am facing the problem with this import from langchain.chains.openai_functions import create_qa_with_structure_chain

it is giving an error No module named 'langchain.chains.openai_functions'

[abhijithjainn]

Same here this is not working "from langchain.chains.question_answering import load_qa_chain"

I am trying to do it on a server I rent but the server has Python 3.7.3 so I cant upgrade python. Is there a way to downgrade langchain? Or buypass it in any other way?

[MannJadwani]

have the same issue, I am not able to import anything from openai_functions

Hi, @fatjoni. I'm Dosu, and I'm here to help the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.

Based on my understanding, you are experiencing a "ModuleNotFoundError" when trying to import "CONDENSE_QUESTION_PROMPT" from the "langchain.chains.chat_index" module in the latest version (0.0.123) of the software. Other users have also encountered similar import issues with different modules. Some users have suggested trying different import statements or updating the Python version, while others have resolved the issue by setting up a fresh environment. One user is unable to upgrade Python and is looking for a way to downgrade langchain or find an alternative solution.
