At a glance

The community member is trying to load PDF tables using PDFTableReader() from the llama-hub library, but is encountering an error related to the deprecated PdfFileReader class in the PyPDF2 library. The community member is wondering if they should replace PDFTableReader() with PyPDF to properly read the tables.

In the comments, other community members suggest that the issue might be related to the Camelot library, which is used by the loader. They recommend checking if Camelot is properly installed and upgrading it if necessary. One community member mentions that the issue works fine on their machine, while another suggests starting with a fresh virtual environment if the problem persists.

hmm thats weird, the loader uses camelot -- maybe an issue with the camelot package? https://github.com/emptycrown/llama-hub/blob/00f82de29cdf9c631d872a5c209a3fe9237fd3ab/llama_hub/pdf_table/base.py#L42

i can't do anything without you updating the package, right? can you check please if it generates a similar error on your side?

LLogan M

It works fine on my machine

LLogan M

maybe double check you installed camelot properly

And if you aren't using download_loader, you also have to

Plain Text

pip install --upgrade camelot-py opencv-python ghostscript

I would start with a fresh venv if you have troubles after that
