Hello  
I’m trying to use the solver Mosek to solve a SDP problem via the “Powermodels.jl” library. My code is very simple:  
using powermodels  
using MosekTools  
solver4 = Mosek.Optimizer;  
SDP\_relax=run\_opf(“pglib\_opf\_case3\_lmbd\_\_sad.m”, SDPWRMPowerModel, solver4);

I get the following output:
