I am trying to build a webapp using StreamLit for reading documents (mainly pdf) and load the data using langchain.document_loaders.PyPDFLoader but I am ending up with an error as follows:
TypeError: stat: path should be string, bytes, os.PathLike or integer, not list File "/opt/homebrew/lib/python3.11/site-packages/streamlit/runtime/scriptrunner/script_runner.py", line 552, in _run_script exec(code, module.__dict__) File "/Users/shuhulhandoo/MetaGeeks/PDF-URL_QA/app.py", line 133, in main() File "/Users/shuhulhandoo/MetaGeeks/PDF-URL_QA/app.py", line 75, in main loader = PyPDFLoader(pdf) ^^^^^^^^^^^^^^^^ File "/opt/homebrew/lib/python3.11/site-packages/langchain/document_loaders/pdf.py", line 92, in __init__ super().__init__(file_path) File "/opt/homebrew/lib/python3.11/site-packages/langchain/document_loaders/pdf.py", line 42, in __init__ if not os.path.isfile(self.file_path) and self._is_valid_url(self.file_path): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "", line 30, in isfile import streamlit as st from langchain.document_loaders import PyPDFLoader uploaded_file = st.file_uploader("Upload PDF", type="pdf") if uploader_file is not None: loader = PyPDFLoader(uploaded_file) I am trying to use PyPDFLoader because I need the source of the documents such as page numbers to be saved up. I tried adding the texts of each page in the pdf document page-wise as follows:
from PyPDF2 import PdfReader import streamlit as st uploaded_file = st.file_uploader("Upload PDF", type="pdf") if uploaded_file is not None: texts = "" reader = PdfReader(uploaded_file) for page in reader.pages: texts += page.extract_text()
