ImportError: No module named PyQt5

I get this error when I try to import matplotlib.pyplot with an Anaconda distribution of Python 2.7 running in a command window, on a windows X64 machine with Windows 10. I can import the module from within my Jupyter notebook just fine. Is there a fix for this?

The whole traceback is:

C:\Users\You>python

Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib.pyplot

As mentioned in the comments, you have to import matplotlib first, change the backend and then import pyplot. 

>>> import matplotlib
>>> matplotlib.use('Qt4Agg')
>>> import matplotlib.pyplot
