python - Networkx: find way according to .dot file attribute -


i'm working digraph defined in dot language using networkx. need achieve this:

 x = networkx.read_dot('_t.dot')  #loads dotfile  def navigate_through_model(model, type):  #model model, type -> string of desired 'comment'     .....     return path   if \__target\__== '\__main\__':     print navigate_through_model(x, 'regression') # need return path, going through nodes comment == 'regression'  (it can other attribute, comment question)

and i'm kind lost in :(

any appreciated.

ok found (after sleep) can use weight of edges achieve same result. solution easy.. set lowest weight 'regression' path , generate shortest path.

networkx(x, 'start', 'end', weight='weight')

in order have edit networkx/algorithms/shortest_paths/weighted.py
there kind of bug on row 342.

vw_dist = dist[v] + edgedata.get(weight, 1)

you have change to:

vw_dist = dist[v] + float(edgedata.get(weight, 1))   #if want use floating number or int use integers
