Problem using functions from ScenTrees Package

heiwie · February 9, 2024, 2:53pm

I am trying to run the same code as in the official github repo for the ScenTrees package (GitHub - aloispichler/ScenTrees.jl: Julia Package for Generating Scenario Trees and Scenario Lattices for Multistage Stochastic Optimization). This code is the following:
using ScenTrees
gstree = tree_approximation(Tree([1,2,2,2],1),gaussian_path1D,100000,2,2);
tree_plot(gstree)

I have added the ScenTrees package to my environment, but it seems like the functions defined in the package is not accessible. I get the following error:

I am new to Julia, so any guidance here would be much appreciated:)

Perhaps try with a !?

github.com

aloispichler/ScenTrees.jl/blob/ed31379b453c9e05656937b9d661035f9de63acf/src/ScenTrees.jl#L8


      
          module ScenTrees
          include("TreeStructure.jl")
          include("TreeApprox.jl")
          include("StochPaths.jl")
          include("LatticeApprox.jl")
          include("KernelDensityEstimation.jl")
          include("bushinessNesDistance.jl")
          export tree_approximation!,lattice_approximation,Tree,Lattice,stage,height,leaves,nodes,root,
                  part_tree,build_probabilities!,tree_plot,plot_hd,plot_lattice,gaussian_path1D,gaussian_path2D,
                  running_maximum1D,running_maximum2D,path,bushiness_nesdistance,kernel_scenarios
          end

Tried it, didnt work unfortunately…

Yes the package looks to be in need of some updates. For me the code crashes Julia instantly with:

Intel MKL FATAL ERROR: Cannot load libmkl_intel_thread.1.dylib.

Perhaps contact the author via a Github issue?
