Errors while processing files

[Janarthananvt07]

Followed your step by creating environment, installed requirement.txt and created .env(without a file name, just the extension).

Ran the command streamlit run app.py

Scenario 1 (Some files were unable to process)

While testing theSubmit and proccess functionality on the local host page, I encountered an issue with processing certain PDF files. Upon attempting to submit and process them, I received the following error.

LangChainDeprecationWarning: Importing vector stores from langchain is deprecated. Importing from langchain will no longer be supported as of langchain==0.2.0. Please import from langchain-community instead:

`from langchain_community.vectorstores import FAISS`.

To install langchain-community run `pip install -U langchain-community`.
  warnings.warn(

Even after installing langchain-community using the pip install command, I'm still unable to import it.

import langchain-community
  Cell In[2], line 1
    import langchain-community
                    ^
SyntaxError: invalid syntax

Scenario 2 (Some files were able to be processed)

Upon opening the localhost page, I immediately receive a warning regarding the langchain_community module. However, when attempting to submit and process a simple PDF file, there are no errors displayed on the webpage or the terminal. However, when I begin to ask a question, I encounter the following error on the webpage

and in the terminal

Am i following the right steps as mentioned by you?

• Is the .env file naming convention is right, just the extension without the file name.
• Are any other packages (versions) or modules to be installed to the environment.
  Can you please help me?
  Thanks.
