This is a numpy error. It indicates that your data somehow contains incorrect values, for example you try to take the square root of negative numbers, or 1/a where a (which is an array) contains zeroes.
I think this might be caused by your calculations not converging properly, perhaps to a state with no electrons left in the central region. Do you have the output log of the calculation?
