How to save vector of vectors with different dimensions?

Hey ! I am looking for the optimal way of saving a vector of vectors in which each vector has different dimensions. The major problem is that I cannot save it as a df then get it as a CSV file…
Thanks for your help !

You can use JLD2.jl. A quick example:

julia> import JLD2

julia> x = [[1,2,3], [1,2], [1,2,3,4]]
3-element Vector{Vector{Int64}}:
 [1, 2, 3]
 [1, 2]
 [1, 2, 3, 4]

julia> JLD2.save_object("test.jld2", x)

julia> y = JLD2.load_object("test.jld2")
3-element Vector{Vector{Int64}}:
 [1, 2, 3]
 [1, 2]
 [1, 2, 3, 4]

julia> x == y
true

Another possibility is JLSO.jl:

julia> using JLSO

julia> x = [[1, 2, 3], [1, 2], [1, 2, 3, 4]]
3-element Vector{Vector{Int64}}:
 [1, 2, 3]
 [1, 2]
 [1, 2, 3, 4]

julia> JLSO.save("test.jlso", :myarray => x)

julia> loaded = JLSO.load("test.jlso")
Dict{Symbol, Any} with 1 entry:
  :myarray => [[1, 2, 3], [1, 2], [1, 2, 3, 4]]

julia> y = loaded[:myarray]
3-element Vector{Vector{Int64}}:
 [1, 2, 3]
 [1, 2]
 [1, 2, 3, 4]

julia> x == y
true
