How do you pass a variable list of arguments in pythonnet? The problem is the function numpy.gradient(f, *varargs, axis=None, edge_order=1) as documented here: https://numpy.org/doc/stable/reference/generated/numpy.gradient.html

Here is an example in python

>>> import numpy as np
>>> dx=4.0
>>> dy=5.0
>>> zX=[[1,2,3],[4,5,6],[8,9,0]]
>>> np.gradient(zX, dx, dy)
[array([[ 0.75 ,  0.75 ,  0.75 ],
       [ 0.875,  0.875, -0.375],
       [ 1.   ,  1.   , -1.5  ]]), array([[ 0.2,  0.2,  0.2],
       [ 0.2,  0.2,  0.2],
       [ 0.2, -0.8, -1.8]])]
>>>

I tried to pass the variable args with the args tuple but then the python function complains that the number of arguments is incorrect.

Python.Runtime.PythonException: TypeError : invalid number of arguments
 ['  File "C:\\Users\\henon\\AppData\\Local\\python-3.7.3-embed-amd64\\lib\\numpy\\lib\\function_base.py", line 1013, in gradient\n    raise TypeError("invalid number of arguments")\n']   at Python.Runtime.PyObject.Invoke(PyTuple args, PyDict kw)
   at Python.Runtime.PyObject.InvokeMethod(String name, PyTuple args, PyDict kw)

I also tried to pass it as kw["varargs"] but then python says there is no kwarg named "varargs"

So how to call that function?
