cannot parse dot data

[IARI]

  File "/usr/local/lib/python3.4/dist-packages/pydot/dot_parser.py", line 511, in parse_dot_data
    if data.startswith(codecs.BOM_UTF8):
TypeError: startswith first arg must be str or a tuple of str, not bytes

I believe this has been addressed before
pydot/pydot#76

but somehow apparently it is not in pydot3 (I do not understand where and why what version of pydot is - but i am assuming I have this one having installed pydot via pip3 install pydot3)
