Summary
I am using cyipopt to solve Pyomo models with GreyBox. After cyipopt finds the optimal solution, it returns the optimal solution and duals. However, the key of the duals of the GreyBox is a dict(), which might not be very straightforward.
Example:
dual : Direction=Suffix.IMPORT, Datatype=Suffix.FLOAT
Key : Value

Since there is even no Object named my_block.egb.output_constraints, can we simplify the key of the duals to my_block.egb.outputs[log_det]?
