Python Kernel died when using Gurobi in Enthought Canopy on Win 7 -


i trying use gurobi python solve mixed integer optimization problem, every time run code wrote according gurobi tutorial, message popped up, saying: "the kernel has died, restart it? if not restart kernel, able save notebook, running code nor work until notebook reopened."

i used enthought canopy python 2.7 , gurobipy gurobi on win 7.

here small trial optimization problem tried solve, , message above showed after run it:

import gurobipy import numpy gurobipy import *   def minvol(n1,solution):     model=model()    x=model.addvar(lb=0.0,ub=1.0,vtype=grb.continuous)    y=model.addvar(lb=0.0,ub=1.0,vtype=grb.continuous)     model.update()    varibles=model.getvars()     model.setobjective(2*x+y,grb.maximize)    model.update()     model.optimize()     if model.status==grb.optimal:        s=model.getattr('s',varibles)        in range(n1):            solution[i]=s[i]        return true    else:        return false n1=2 solution=[0]*(n1) success=minvol(n1,solution) if success:    print solution 

anyone me this? thank much!
