Error when importing model with aggregate section

[ezgioz]

Can not import the CS model:

mc = exogenous.discretize(to='mc', options=[{}, discretization_options])
to='mc' should be corrected

Error message:
~/EconForge/dolARK/dolark/perturbation.py in init(self, model, dr0, discretization_options, exo_grid, endo_grid)
39 # by default grids for the distribution are taken from model/d.r.
40 exogenous = copy.deepcopy(model.exogenous)
---> 41 mc = exogenous.discretize(to='mc', options=[{}, discretization_options])
42 exo_grid = mc.grid
43 endo_grid = model.get_grid()
