### TypeError: Computation failed since Maxima requested additional constraints

I have the following code: N, n, f = var('N, n, f') assume(N>0) sum(binomial(N, n)f^n(1-f)^(N-n), n, (N+1)/2, N)

It gives me the following error message: TypeError: Computation failed since Maxima requested additional constraints (try the command 'assume(N+1>0)' before integral or limit evaluation, for example): Is N+1 positive, negative, or zero?
