Hi @hz-xiaxz, try with this code:

> [@Bottleneck of JuMP](https://discourse.julialang.org/t/bottleneck-of-jump/136609/21):
>
> Try with: function dual\_optimizer() inner = MosekTools.Optimizer() dual\_problem = Dualization.DualProblem{Float64}(inner) return Dualization.DualOptimizer{Float64,typeof(inner)}(dual\_problem) end model = Model(dual\_optimizer) The underlying issue is: Mosek does not support HermitianPSDCone directly, so JuMP reformulates the problem into a larger PSD model. Model(Dualization.dual\_optimizer(Mosek.Optimizer)) creates two sets of bridges: one before the dual\_optimizer and one betwee…
