Error in the example code "Modelling the Cavitation"

[Sriram14357]

I am getting errors in line 3 in the boundary condition section. can any one tell me why?

inlet_1 = solver.setup.boundary_conditions.pressure_inlet["inlet_1"].phase

inlet_1["mixture"] = {
    "momentum": {
        "gauge_total_pressure": {"value": 500000},
        "supersonic_or_initial_gauge_pressure": {"value": 449000},
        "direction_specification_method": "Normal to Boundary",
    },
    "turbulence": {
        "turbulent_specification": "Intensity and Viscosity Ratio",
        "turbulent_intensity": 0.05,
        "turbulent_viscosity_ratio_real": 10,
    },
}

I encountered the same error and I hope someone can solve it.
