Hi!
I’m trying to use [GitHub - madeleineudell/SigmoidalProgramming.jl: Julia Package for Sigmoidal Programming](https://github.com/madeleineudell/SigmoidalProgramming.jl)
The `Project.toml` looks like:
```julia
name = "SigmoidalProgramming"
uuid = "ce2a0656-6bed-5c64-9e01-e7b1ac833b80"
keywords = ["sigmoidal programming", "branch and bound"]
license = "MIT"
version = "1.0"
[deps]
Clp = "e2554f3b-3117-50c0-817c-e040a3ddf72d"
DataStructures = "864edb3b-99cc-5e75-8d2d-829cb0a9cfe8"
GLPK = "60bf3e95-4087-53dc-ae20-288a0d20c6a6"
JuMP = "4076af6c-e467-56ae-b986-b466b2749572"
MathOptInterface = "b8f27783-ece8-5eb3-8dc8-9495eed66fee"
[compat]
julia = "1.3"
Clp = "0.8"
DataStructures = "0.18"
GLPK = "0.14"
JuMP = "0.21"
MathOptInterface = "0.9"
```
However,
calling
```julia
import SigmoidalProgramming
```
results in
```julia

I’ve already tried:
```julia
Pkg.update()
Pkg.recompile()
```
My julia was installed with
```julia
brew install --cask julia
```
I’m running MacOS 10.14 Mojave on Intel

SigmoidalProgramming.jl is a bit old and unmaintained.
There were some issues with old versions of Clp that we fixed, but it looks like you can’t get the latest releases because of the requirement that you use old versions of Clp, JuMP, and MathOptInterface (all are version 1.0 or later now).
Try explicitly installing this version of MUMPS to see if that fixes the problem:
```julia
import Pkg
Pkg.pkg"add MUMPS_seq_jll@5"
```

Also note that there are no tests:
[SigmoidalProgramming.jl/runtests.jl at master · madeleineudell/SigmoidalProgramming.jl · GitHub](https://github.com/madeleineudell/SigmoidalProgramming.jl/blob/master/test/runtests.jl),
so I don’t know if Madeleine ever intended this for widespread usage.

Thanks!
Not a problem, just using this for a school project.
I think the MUMPS thing worked…but I had to do it through the repl. Is it possible to run the notebook using a Julia Project.toml (a la running ipython in a pyenv)?

Yes, make this your first cell:
```julia
import Pkg
Pkg.activate("/path/to//Project.toml")
```
You’ll need to add a `MUMPS_seq_jll = "5"` line to the `[compat]` section of your `Project.toml`.
Your other option is to use a local copy of `SigmoidalProgramming.jl` with some edits.
```julia
import Pkg
Pkg.dev("SigmoidalProgramming")
```
Then look in `~/.julia/dev/SigmoidalProgramming` and edit the `Project.toml` to update the bounds to:
```julia
[compat]
julia = "1.6"
Clp = "1"
DataStructures = "0.18"
GLPK = "1"
JuMP = "1"
MathOptInterface = "1"
```
It looks like a simple package, so that might be enough.

Hey @odow, thanks for the update! I’ve packaged my work up into a github repo for use inside my research group, using the first approach. For the base julia package, would it be advisable/useable to make a PR adding the `a MUMPS_seq_jll = "5"` update?

No. The problem only happens for old Clp.jl versions. For newer versions, we fixed the bug.
The real solution is to update `SigmoidalProgramming` to the version 1 releases of JuMP, MathOptInterface, and Clp.
Or I need to fix this instead: [https://github.com/JuliaRegistries/General/blob/master/C/Clp\_jll/Compat.toml](https://github.com/JuliaRegistries/General/blob/master/C/Clp_jll/Compat.toml)
