This means that you are passing a matrix (an `Array{Int64, 2}` which is the same as a `Matrix{Int64}`) to a function which expects a vector (an `Array{Int64, 1}` which is the same as a `Vector{Int64}`).

However, without being able to see the full inputs or error message, it’s difficult to say how to fix it. Please take a look at [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)
