Conversion failed (MathOptInterface.Utilities.VectorOfConstraints)

[victorgarciareolid]

Hi all!

I've been trying to run the farmer problem example but it failed (this in Julia 1.5.3). I made a fresh Julia 1.6.1 installation and the exampled failed as well. Furthermore, I run the test and many failed. I attatch you the test summary as well as the the error in common.

I hope it helps :)

Cheers,

This looks like a problem with the new MOI release.

To fix temporarily until @martinbiel fixes this in StochasticPrograms, do ] add MathOptInterface@0.9.20, then restart Julia.

This has been fixed on master: https://github.com/martinbiel/StochasticPrograms.jl/commit/baf67f19b47f4929848dc90167d1ff3d4d3cec12. I will push a new release soon, and until then ] add StochasticPrograms#master also works as a temporary fix :slightly_smiling_face:
