bounds error #118

Closed stumarcus314 closed 4 years ago

stumarcus314 commented 5 years ago

I get the following error. Might this have something to do with Julia v0.6.4 vs v0.7?

ERROR: LoadError: BoundsError: attempt to access 3×5 Array{Variable,2} at index [1, 1, 5] Stacktrace: [1] macro expansion at ./array.jl:732 [inlined] [2] MVB_MINLP_Alpine(::Array{Float64,2}, ::Bool, ::AlpineSolver, ::Bool, ::Bool, ::Array{Int64,1}, ::Array{Int64,1}, ::Float64, ::Float64) at /Users/a598124/juliaCode/pre19/MVB_MINLP_Alpine.jl:84 [3] top-level scope at /Users/a598124/juliaCode/pre19/hydrox_Alpine.jl:328 [4] include at ./boot.jl:317 [inlined] [5] include_relative(::Module, ::String) at ./loading.jl:1038 [6] include(::Module, ::String) at ./sysimg.jl:29 [7] exec_options(::Base.JLOptions) at ./client.jl:239 [8] _start() at ./client.jl:432 in expression starting at /Users/a598124/juliaCode/pre19/hydrox_Alpine.jl:205

Does this run fine in v0.6.4 but not in v0.7? It looks like an error in accessing your variables. Post a simple version of the code which reproduces this error.

stumarcus314 commented 5 years ago

The code works okay in v0.6.4, but using P.W.L. of the nonlinear objective and solving the model as a MILP, since I can't install Alpine in v0.6.4. I get the same bounds error in v0.7 when using P.W.L. of the nonlinear objective and solving the model as a MILP.

The error says: attempt to access 3×5 Array{Variable,2} at index [1, 1, 5]. Does Variable refer exclusively to a continuous variable rather than a binary variable? In this instance of my model, n=5. In my model, there is a 3x5 matrix X of continuous variables defined as follows: @variable(m,0 <= X[d=1:3,i=1:n] <= upper_x[d]-min_p[i]) # coordinates of left-back-bottom corner of each carton If the error corresponds to X, why would JuMP attempt to access index [1, 1, 5]?

Try updating Julia to v1.0, updating alpine to v1.9. If this error persists then please post an example so that we can replicate it on our side.

@stumarcus576 If you see this error again, feel free to re-open this issue.
