PyPDF2.PdfFileReader hangs indefinitely - pypdf

Question

I'm trying to read this pdf file (https://www.accessdata.fda.gov/cdrh_docs/pdf14/K141693.pdf) and am following these suggestions from SO
Opening pdf urls with pyPdf
I have actually downloaded the file locally and am running the following code
import PyPDF2
pdf_file = open("K141693.pdf")
pdf_read = PyPDF2.PdfFileReader(pdf_file)
but my code hangs indefinitely. I'm running Python 2.7 and here is the stacktrace.
Traceback (most recent call last):
File "", line 1, in
runfile('C:/PoC/pdf_reader.py', wdir='C:/PoC')

KeyboardInterrupt
I came across another post here PyPDF2 hangs on processing but that too doesn't have a response.

Answer 1

You need to parse the file in binary ('rb') mode. (This works in Python 3:)
import PyPDF2
pdf_file = open("K141693.pdf", "rb")
read_pdf = PyPDF2.PdfFileReader(pdf_file)
