ellipses (`...`) as indices on numpy array:

[Alexander-Barth]

I am trying to wrap a python code from a colleague. I would like to avoid any changes to the python code that makes the python code less general. I have a problem when the code uses ellipses (...) as indices on numpy array:

Is your feature request related to a problem? Please describe.

Consider the python code (in file test_ellipsis.py) :

def test_ellipsis(X):
    print("sum", X[0,...].sum())

The code is called in julia as:

using PythonCall
pyimport("sys").path.append("/add/file/path/to/python/script/")
pyimport("test_ellipsis").test_ellipsis(randn(2,2,2))

Unfortunately, the produces the error:

ERROR: Python: TypeError: expecting 3 indices, got 2
Python stacktrace:
 [1] __getitem__
   @ ~/.julia/packages/PythonCall/83z4q/src/JlWrap/array.jl:350
 [2] test_ellipsis
   @ test_ellipsis ~/src/NEDAS-test/NEDAS_tutorials/test_ellipsis.py:2

Describe the solution you'd like

Could indexing of ellipses be supported in PythonCall.jl for numpy arrays ?

Describe alternatives you've considered

I could create a np.array from the julia side, for example:

np = pyimport("numpy")
pyimport("test_ellipsis").test_ellipsis(np.asarray(randn(2,2,2)))

Additional context

I am using julia 1.12 on Linux with PythonCall v0.9.31 and Numpy 2.5.3.

Btw, thanks for the great package!!
