Web1 You should modify x >= lower and x <= upper to (x >= lower) & (x <= upper) . The problem is that logical evaluations with SymPy objects can return an another symbolic logic that cannot be deduced to True or False. You can see how (x >= lower).__class__ returns an another sympy inequality instance.
