SciPy

What happened:

If a negative value for drop_axis is passed into either map_blocks or map_overlap a non-informative exception is raised.

What you expected to happen:

I would expect this would work as in NumPy for negative axis arguments where axis becomes axis = axis % array.ndim. If it is not intended to work, then it should raise a user-friendly AxisError. This came up

issue

i traied use hess= {2-point’, ‘3-point’, ‘cs’, HessianUpdateStrategy} according to doc,but it failed.

Reproducing code example:

import numpy as np
from scipy.optimize import minimize,show_options,SR1
import sys
def rosen(x):
    """The Rosenbroc

What's wrong?

Description of the desired feature

The spacing parameter of the rolling_window function controls the distance between the center of two adjacent windows.
Nevertheless, the docstring reads:

    spacing : float, tuple = (s_north, s_east), or None
        The window size in the South-North and West-East directions,
        respectively. A single value means that the size is equal
