Unpack NumPy array by column

Question

If I have a NumPy array, for example 5x3, is there a way to unpack it column by column all at once to pass to a function rather than like this: my_func(arr[:, 0], arr[

Answer 1

I guess numpy.split will not suffice in the future. Instead, it should be

my_func(tuple(numpy.split(array, 3, 1)))

Currently, python prints the following warning:

FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use arr[tuple(seq)] instead of arr[seq]. In the future this will be interpreted as an array index, arr[np.array(seq)], which will result either in an error or a different result.
