MOI no method matching _allocate_constraint

[ccoffrin]

With Julia v0.6.4, JuMP master, SCS master, and MOI v0.6.1.

With the following JuMP model,

using JuMP; using SCS

using MathOptInterface
const MOI = MathOptInterface
const MOIU = MOI.Utilities

m = Model()

X = @variable(m, [1:3, 1:3])

@constraint(m, X in PSDCone())

MOIU.resetoptimizer!(m, SCS.Optimizer())
JuMP.optimize!(m)

I am getting the following error message,

ERROR: MethodError: no method matching _allocate_constraint(::SCS.ConeData, ::MathOptInterface.VectorOfVariables, ::MathOptInterface.PositiveSemidefiniteConeSquare)

Bridges currently don't work if you do not provide the optimizer from the start.
Try

using JuMP; using SCS

using MathOptInterface
const MOI = MathOptInterface
const MOIU = MOI.Utilities

m = Model(with_optimizer(SCS.Optimizer))

X = @variable(m, [1:3, 1:3])

@constraint(m, X in PSDCone())

JuMP.optimize!(m)

Note that the new syntax is JuMP.optimize!(m, with_optimizer(SCS.Optimizer)) instead of calling resetoptimizer!. We should have a better error.

Thanks for the clarification on the new syntax. I can confirm the example you provide works like a charm.

However, if I try to set the optimizer at the time of optimize! then I still have an issue,

using JuMP; using SCS

m = Model()

X = @variable(m, [1:3, 1:3])

@constraint(m, X in PSDCone())

JuMP.optimize!(m, with_optimizer(SCS.Optimizer))

results in,

Thanks for checking that. This is problematic but should be resolved by jump-dev/JuMP.jl#1504 and jump-dev/MathOptInterface.jl#530. There is nothing wrong in SCS.jl so I am closing this issue.
