I am using a python based Tight binding code Pybinding, while importing it I get following error:
>>> import pybinding as pb
Traceback (most recent call last):

cbook._putmask(xa, xa == 1.0, almost_one)
AttributeError: module 'matplotlib.cbook' has no attribute '_putmask'I have tried all the troubleshooting procedures posted on here: Stack overflow link
Also install and reinstall matplotlib and pybinding package but it has not solved my issue. I am using fedora 27 as my operating system and output imp.find_module is:
(None, '/usr/lib64/python3.6/site-packages/matplotlib', ('', '', 5))
