Python PDF text extraction

Question

I am trying to extract text from a PDF file, below is my code:

file_path = "xxx.pdf"

pdfFileObj = open(file_path, 'rb') 
pdfReader = PyPDF2.PdfFileReader(pdfFileObj) 

print(pdfReader.numPages) 

pageObj = pdfReader.getPage(0) 
    
print(pageObj.extractText()) 
    
pdfFileObj.close()

After running the code, I kept getting the error message:
---> print(pageObj.extractText())
AttributeError: 'NameObject' object has no attribute 'get_data'

The output is like:

68
Output exceeds the size limit. Open the full output data in a text editor

    206     )

AttributeError: 'NameObject' object has no attribute 'get_data'

And I couldn't find any similar error, and the weird thing is that the code went well with other files but not with this specific one.

Does anyone have any idea what could happen with my code or the PDF file?

Try reinstalling the PyPDF2 library.

pip uninstall pypdf2

pip install pypdf2
