AttributeError: module 'numpoly' has no attribute 'variable for the coffe cup example

[moja84]

Hello
I used chaospy in order to perform sensitivity analsises some time ago and want now to continue this work but get the following error. In order to exclude the error in my program I tried the example https://uncertainpy.readthedocs.io/en/latest/examples/coffee_cup.html
On Fedora 33 with chaospy-4.2.5, and Python 3.8.7
And get the same error

Traceback (most recent call last):

AttributeError: module 'numpoly' has no attribute 'variable'

I will be very pleased to recieve help since I need chaospy for my research.

A new installation/update of the numpoly library with the new git version solved my issue. :)
