There are several issues with the example files, I think there is a plan to update those in the near future? Another thing to consider is whether you are using Pythonnet > 2.5.2:

• PythonNET 3.x is "Fixed"

Regarding the transpose though, ANYS have defined their own transpose in the boilerplate template:

def transpose(data):
    """Transposes a 2D list (Python3.x or greater).  

    Useful for converting mutli-dimensional line series (i.e. FFT PSF)

    Parameters
    ----------
    data      : Python native list (if using System.Data[,] object reshape first)    

    Returns
    -------
    res       : transposed 2D list
    """
    if type(data) is not list:
        data = list(data)
    return list(map(list, zip(*data)))

Take care,
