It seems you're encountering an issue with importing PDFDocument from pdfminer.pdfparser. Let's rephrase your request for clarity and correctness: "I need to extract text from PDF files, and I've been successful using pdfminer.six to extract both text paragraphs and tables. 
However, I'm now encountering an error related to the line 
ImportError: cannot import name 'PDFDocument' from 'pdfminer.pdfparser' (C:\Users\ashok\python\lib\site-packages\pdfminer\ 
I've attempted to uninstall and reinstall Anaconda, pdfminer.six, and other related packages multiple times. About 2-3 days ago, the code suddenly worked, but now the error has resurfaced. Since I'm using Windows 10, I also tried using Linux Ubuntu but encountered the error.
After struggling for hours, I've managed to fix the problem. In this post, we're going to discuss possible solutions for this error.

We made the following changes to address the issue:

We updated our import statements as follows:

from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfpage import PDFPage

Additionally, we adjusted the instantiation of the PDFDocument object to include the PDFParser:

parser = PDFParser(pdf_file)
doc = PDFDocument(parser)

Furthermore, we modified the loop to create pages using the PDFPage module:

for page in PDFPage.create_pages(doc):

It's important to note that according to the pdfminer documentation, the PDFDocument should be imported from pdfminer.pdfdocument.

By correctly importing the required modules and adjusting the instantiation of the PDFDocument object, we ensure compatibility and proper functioning of the code.
