QPDF giving file not found error in python

Question

I am using qpdf to decrpyt pdf files (encrytpted but without password) as pypdf2 decryption doesn't work. It is working on command line but with python giving FileNotFoundError

qpdf --decrypt --replace-input test.pdf # it's working; replacing test.pdf with the absolute path

But with python it doesn't

inp_file = open(self.path, "rb")
inp_pdf = PdfFileReader(inp_file)
if inp_pdf.isEncrypted:
    try:
        inp_pdf.decrypt('')
    except:
        subprocess.run(["qpdf", "--decrypt", "--replace-input", self.path)])

With a debugger, you should investigate if "FileNotFoundError" is related to qpdf or to self.path. — AndrewQ, Apr 13 '20 at 10:51

I switched to pikepdf. It is built on top of QPDF; brief description in quotes below. It's very simple to create new pdfs based on exisiting pdfs. Also, it handles decryption on the fly.

Pikepdf provides a Pythonic wrapper around the C++ PDF content transformation library, QPDF.

It doesn't implement text extraction from pdfs; I used tika for text extraction.
