C++ to Python conversion crash

[YorchMcM]

The function io.read_vector_history_from_file crashes when used on Python and gives the following error:

TypeError: Unable to convert function return value to a Python type! The signature was
(vector_size: int, file_name: str) -> Dict[float, Eigen::Matrix<double,-1,1,0,-1,1>]

Something similar happens with the function numerical_simulation.propagation.get_zero_normal_mode_rotational_state, although the error reads somewhat different:

TypeError: Unable to convert function return value to a Python type! The signature was
(bodies: tudatpy.kernel.numerical_simulation.environment.SystemOfBodies, integrator_settings: tudat::numerical_integrators::IntegratorSettings, propagator_settings: tudat::propagators::SingleArcPropagatorSettings<double,double>, body_mean_rotational_rate: float, dissipation_times: List[float], propagate_undamped: bool = True) -> Tuple[numpy.ndarray[numpy.float64[m, 1]], List[Tuple[Dict[float, numpy.ndarray[numpy.float64[m, 1]]], Dict[float, numpy.ndarray[numpy.float64[m, 1]]]]], List[Tuple[Dict[float, numpy.ndarray[numpy.float64[m, 1]]], Dict[float, numpy.ndarray[numpy.float64[m, 1]]]]]]

I've been told you are aware of this and that for some people this doesn't happen. I attach the contents of my conda environment so that hopefully the problematic module(s) can be identified.

The exposure of read_vector_history_from_file will be fixed in #217.
@DominicDirkx I couldnt find any reference to get_zero_normal_mode_rotational_state. Has this function been renamed or removed?

[DominicDirkx]

This function is now called get_damped_proper_mode_initial_rotational_state. Thanks for trying to fix this!

[larshinueber]

Thanks! It seems that this has been fixed in the meantime (checked with the dev version) and there is even an example using the function: https://docs.tudat.space/en/latest/_src_getting_started/_src_examples/tudatpy-examples/propagation/coupled_translational_rotational_dynamics.html#Getting-rid-of-the-normal-modes
