Hello team!

At a glance

The community member is trying to read documents using SimpleDirectoryReader, but is encountering an error with a PPTX file that contains images. They have tried converting the PPTX file to PDF, but that also gives an error. The issue seems to be related to the PIL library's inability to read the WMF image format. Community members have suggested running a code to list the image formats supported by PIL, and checking if WMF is present. They have also suggested using a different library, such as the PptxReader from the llama_index package, which appears to have worked for one of the community members.

Hello team!
i'm trying to read documents using SimpleDirectoryReader but it gives this error.
The error is coming from a pptx file that contains images.

def get_file_metadata(filename: str) -> Dict:
    file_name = os.path.basename(filename)
    file_name_without_extension = os.path.splitext(file_name)[0]
    metadata = {"file_name": file_name_without_extension}
    return metadata

chatbot_data = SimpleDirectoryReader("data/", file_metadata=get_file_metadata).load_data()

Here is my code for Reading Data folder

@Ahsan Mirza seems like the issue is with PIL while reading image.

rravitheja

If you are converting it to PDF and trying with SimpleDirectoryReader not sure if the images in pdf will be read by 'pypdf'

rravitheja

from PIL import Image

print(Image.registered_extensions())

rravitheja

can you try running this code?
This will list the image formats PIL supports on your system. Check if WMF format is present in the output. If not that is the issue here.

AAhsan Mirza

please guide me where should i run this code?

rravitheja

python shell/ jupyter notebook

@Logan M @ravitheja

rravitheja

Okay. Interesting, PIL supports WMF but it seems its unable to recognize the format. Weird.

AAhsan Mirza

AAhsan Mirza

@Ahsan Mirza If you can share the pptx on DM, I can try checking on my end.

AAhsan Mirza

@ravitheja check your dm

rravitheja

from pathlib import Path
from llama_index import download_loader

PptxReader = download_loader("PptxReader")

loader = PptxReader()
documents = loader.load_data(file=Path('./Bank_book_PP_draft.pptx'))

rravitheja
