I have some code that builds a number of VPTrees via VPTrees.jl and the building of these trees takes a long time. I’d like to be able to simply load a pre-built tree into a new session rather than having to re-build the trees each time I close/start a session. Here’s a MWE with JLD.jl and the error message I get:
using JLD
using StringDistances
using VPTrees
metric = (a, b) -> evaluate(Levenshtein(), a, b)
tree = VPTree(["Larry", "Moe", "Curly"], metric)
jldopen("tmp/test.jld", "w") do file
addrequire(file, VPTrees)
write(file, "tree", tree)
end
And the error:
ERROR: UndefVarError: isgeneric not defined

Does someone know how to do this? Thanks!!
