Array.reshape "only allows for reshapings that collapse or merge dimensions" (xref dask/dask#2561). However, when you try to do one of these unsupported reshapings, the error message Shapes not compatible does not make it at all clear that what you're asking for just isn't supported by dask. Instead, it sounds as though your inputs are invalid.

A more descriptive e

Is possible know the mathematical definition of this function?
scipy.special.chndtr
scipy.special.chndtrix

Also this functions:
scipy.special.nctdtr
scipy.special.nctdtrit

Description

Calling vectorize with a non-None value for the signature parameter outputs this error message about the excluded parameter.

NotImplementedError: cupy.vectorize does not support `excluded` option currently.

Inspecting the code, it is obvious there is a copy-paste error and the 2nd error message should be change excluded to signature.

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
