I noticed the following:

x = zeros(1, 100)
r = kmeans(x, 5)

output:

julia> r.centers
1×5 Array{Float64,2}:
 0.0  0.0  0.0  0.0  0.0
julia> r.cweights
5-element Array{Int64,1}:
             100
 140247151137392
 140247151137440
 140247151137488
 140247151137536

The cweights value is problematic. I am using Julia 1.1.1
