pydot and graphviz error: Couldn't import dot_parser, loading of dot files will not be possible

Question

When I run a very simple code with pydot

import pydot
graph = pydot.Dot(graph_type=\'graph\')

for i in range(3):

  edge = pydot.Edge(\"king\", \"lord%d\" %         


        

Answer 1

What I did at the end after so many tries from what i saw here (pseudo sequence for it to work for networkx ) :

apt-get remove python-pydot
pip install pydotplus
apt-get install libcgraph6
apt-get install python-pygraphviz


# pip freeze | grep pydot
 pydotplus==2.0.2
# pip freeze | grep pyparsing
pyparsing==2.2.0
# pip freeze | grep graphviz
pygraphviz==1.2
# python -c 'import pydotplus'
#

Answer 2

There are now at least 2 more versions that appear to support PyParsing-2 and Python-3:

• PyDotPlus by Carlos Jenkins with a nice travis buildbot and fancy documentation. However you will need to change its folder name from site-packages\pydotplus to site-packages\pydot for it to work with existing programs that import pydot.
• pydot3k by bmcorser. Sadly, did not work!
• prologic/pydot by James Mills linked to from the official pydot Google code page as ...

  a branch for Python 3 compatibility

• and here is a working link to David Villa's pydot2 which works fine: https://pypi.python.org/pypi/pydot2/1.0.32
