Archipelago crashes in Linux.

[arita37]

When running in linux, this problem,
--> Island went fine
--> Archipelageo crashes

How to make Archipelago runs under Linux ?

class problem1(pyg.problem.base):     
    def __init__(self, dim=29):
        super(problem1,self).__init__(dim)
        self.__dim= dim

        lbound= list(np.zeros(dim))
        ubound= list(np.ones(dim))
        self.set_bounds(lbound, ubound)

    def _objfun_impl(self, x):
        x= np.array(x, dtype=np.float)
        f= np.sum(x*x-5*x+6)       
        return (f, )

    def human_readable_extra(self):
        return "\n\t Problem dimension: " + str(self.__dim)
