Hello! I searched the web and this repository, but i didnt find a standard way to convert a numpy-array (numpy.float64) to a .NET double-array.

I am coding in C#:

double[] csDoubleArray = // some array
PythonEngine.Initialize();
using (Py.GIL()){
  using PyModule pyModule = Py.CreateScope();
  pyModule.Import("numpy");
  pyModule.Set("csDoubleArray ", csDoubleArray .ToPython());
  pyModule.Exec("npDoubleArray = numpy.array(csDoubleArray)");
  pyModule.TryGet("npDoubleArray", out PyObject? pyObject)
  double[] asArray = (double[])pyObject!.AsManagedObject(typeof(double[]))!;// crashes
}

//Error: PythonException: 'numpy.float64' value cannot be converted to System.Double

AFAIK, i could write a converter (https://github.com/pythonnet/pythonnet/wiki/Codecs:-customizing-object-marshalling-between-.NET-and-Python)

My Question: But there should already be a standard way, right?

Many thanks, MJ:)
