shortest_path() got an unexpected keyword argument 'weighted' (Version 1.8.1)

[LN]

Hi All,

I just started going through the basic of NetworkX as I intend to use if for networks definitions corresponding to constrained shortest path problems. I was playing with one of the initial examples (this is the piece of code I have:)

from networkx import *

g = DiGraph()

g.add_edge('a','b',weight=0.1)

g.add_edge('b','c',weight=1.5)

g.add_edge('a','c',weight=0.1)

g.add_edge('c','d',weight=1.0)

print shortest_path(g,'b','d')

print shortest_path(g,'b','d',weighted=True)

I am getting: "TypeError: shortest_path() got an unexpected keyword argument 'weighted'". I checked in past posts and basically the comments point to a version related issue. I verified and the version installed in my laptop is 1.8.1.

Thanks in advance for any help.

Hey,

Docs: http://networkx.github.io/documentation/latest/reference/generated/networkx.algorithms.shortest_paths.generic.shortest_path.html#networkx.algorithms.shortest_paths.generic.shortest_path

Your argument should be weight="weight".

Thanks in advance for any help.
