quote is no longer a part of base urllib but urllib.parse

[SKimble119]

Running:
graph = _rdf.Graph('rdb2rdf_dm')
results in

ImportError: cannot import name 'quote' from 'urllib' (C:\ProgramData\Anaconda3\lib\urllib_init_.py)

Possible solution:
update _common.py
from
from urllib import quote as _pct_encoded
to
from urllib.parse import quote as _pct_encoded
