Id check to see which matplotlib versions you have rather than the Python version.  Either:-

C:\python
Python 3.6.2rc1 (heads/3.6:268e1fb, Jun 17 2017, 19:01:44) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.__version__
'2.0.0'
>>>

or:-

C:\python -c "import matplotlib;print(matplotlib.__version__)"
2.0.0

Kindest regards.
