add_edge function is broken

[Leticia-maria]

Input:

for i in 1:ncol(df), j in i+1:ncol(df) # iterate over all combinations of columns
           w = dot(df[!, i], df[!, j])        # calculate how many times (i,j) occurs
           if w > 0
               push!(ew, w)
               add_edge!(g, i, j, w)
               push!(pairings,[i,j])
           end
       end

Output:

Hi @davibarreira, very nice work with Julia Tutorials. I suggest you to modify the external packages called in your code. I may provide help, if wanted.

[davibarreira]

Hey @Leticia-maria , thanks. I just tried the notebook here, and everything worked. 😕
I updated the packages to Graphs.jl, which is now the new LightGraphs.jl. Just to be sure, this is about the "Graph with Julia", right?

[Leticia-maria]

Right. Oh, I have tested on REPL, not on Jupyter

[Leticia-maria]

@davibarreira Have you tested using REPL environment?

[davibarreira]

I tested in the REPL, and it worked. What version of the packages are you using?
