Relaxation factors: Pseudo time explicit

[Skibbe95]

The following setup is based on the example: Modeling Cavitation:

controls = solver.settings.solution.controls
controls.p_v_controls.explicit_momentum_under_relaxation = 0.7
controls.p_v_controls.explicit_pressure_under_relaxation = 0.7
controls.species_urf_together = True

methods = solver.settings.solution.methods
methods.p_v_coupling.flow_scheme = "Coupled"
methods.pseudo_time_method.formulation.coupled_solver = "global-time-step"
methods.high_order_term_relaxation.enable = False

pt_explicit = solver.settings.solution.controls.pseudo_time_explicit_relaxation_factor
pt_explicit.global_dt_pseudo_relax["tke"] = 0.3

The last line of code is not working.
How to set up the relaxation factors (turbulence, energy, species etc.) in the right way?

[Skibbe95]

solver.settings.solution.controls.species_urf_together = True

controls = solver.settings.solution.controls
controls.p_v_controls.explicit_momentum_under_relaxation = 0.7
controls.p_v_controls.explicit_pressure_under_relaxation = 0.7

relax = solver.settings.solution.controls.pseudo_time_explicit_relaxation_factor.global_dt_pseudo_relax
print(list(relax))

relax["turb-viscosity"] =  1
relax["body-force"] = 1
relax["k"] = 1
relax["epsilon"] = 1
relax["density"] = 1
relax["temperature"] = 1
relax["species-0"] = 1

This code part works fine for the described problem.
