Error occured when trying to run FedCV-objectdetection-MPI: bash run_simulation.sh [CLIENT_NUM]

mpirun has detected an attempt to run as root. Running at root is strongly discouraged as any mistake (e.g., in defining TMPDIR) or bug can result in catastrophic damage to the OS file system, leaving your system in an unusable state. You can override this protection by adding the --allow-run-as-root option to your cmd line. However, we reiterate our strong advice against doing so - please do so at your own risk.
