x = solver.NumVar(0, 1, 'x')
y = solver.NumVar(0, 2, 'y')
objective = solver.Objective()
objective.SetCoefficient(x, 1)
objective.SetCoefficient(y, 1)
objective.SetMaximization()
solver.Solve()
print('Solution:')
print('x = ', x.solution_value())

And I get this error

I'm having trouble importing the nlopt library in Python 3.7.4.
I'm using anaconda, but as nlopt isn't available through conda install, I've installed nlopt with pip.
Here is the error message:
