So i pip installed pdfminer3k for python 3.6. I was trying to follow some examples in opening and converting PDF files to text and they all require a PDFPage import. This does not exist for me. Is there any work around for this? I tried copying a PDFPage.py from online and saving to the directory where python searches pdfminer but I just got... "Import Error: cannot import name PDFObjectNotFound".

Thanks!

Ah. I guess the PDFPage is not meant for python 3.6. Following example from How to read pdf file using pdfminer3k? solved my issues!
