Couldn't import dot_parser on Python 3.6.4

[huyvohcmc]

>>> import pydot
Couldn't import dot_parser, loading of dot files will not be possible.
>>> 

pip3 freeze | egrep 'pydot|pyparsing'
pydot2==1.0.33
pyparsing==2.2.0

I'm using Python 3.6.4 on a Mac:

pydot2 is installed, not pydot. To install pydot:

pip uninstall pydot2
pip install pydot

With pydot >= 1.2.5 installed via pip, I wouldn't expect any issues with dot_parser (because a suitable version of pyparsing would be installed too.
