On the first run you might get :

• an ImportError from pdfminer library

ImportError: cannot import name 'uint_value' from 'pdfminer.pdftypes' (C:/.../pdfminer/pdftypes.py)

To fix this, please uninstall pdfminer3k and pdfminer.six via pip uninstall pdfminer3k pip uninstall pdfminer.six Then install them again via pip install pdfminer3k pip install pdfminer.six

• a TypeError from Slate3k library

TypeError __init__() missing 1 required positional arg 'parser' in "C:/.../slate3k/classes.py

To fix this you'll need to modify class PDF(list): in C:/.../slate3k/classes.py. In def __init__() change both if PYTHON 3:
to if not PYTHON 3: on lines 58 and 72.
