From the exception, you ought to take two actions.

  1. pip install pypdf
  2. The file_path is not correctly specified. Try this
from langchain_community.document_loaders import PyPDFLoader

loader = PyPDFLoader("example_path/layout-parser-paper.pdf")  # Don't forget the double-quote
pages = loader.load_and_split()
