Hi! We discovered that the can't concat str to bytes error on load() can be fixed :
you must fix a bug on line 271 of pdfquery version 0.4.3 by adding .encode() to the end of page_label
Current:
if 'P' in label_format:
page_label = label_format['P']+page_label
Update to:
if 'P' in label_format:
page_label = label_format['P']+page_label.encode()
Note to newbies: to find where pdfquery.py is installed, reinstall it and read the path
python -m pip install pdfquery
