Hi,

Is there a way to store the solution obtained from Gurobi in one dictionary, where the dictionary key would be the variable name? 

Gurobi has the command Model.getVarByName that can be used inside a for loop, but for our case, we found that this is a very slow process.

  You could use Model.getAttr() to retrieve all of the variable names and values at once:

  mvars = m.getVars()
  names = m.getAttr('VarName', mvars)
  values = m.getAttr('X', mvars)
  result = dict(zip(names, values))

  This should be a bit faster.
