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
