pydot has not been updated to Python 3

Trying to plot an exec graph, this error showed up:
ImportError: pydot could not be loaded: http://code.google.com/p/pydot/

I found pydot2: https://pypi.python.org/pypi/pydot2/1.0.33
Maybe nipype could be moved to use it? I will check if this works.

Yes, it worked without any changes.
pip install pydot2 and it worked the same.

Maybe a change in the error message would be helpful?

Sorry, the error message comes from networkx.
