Hello,

I am currently working with a simple program in Python (just starting out) and 
am getting an error message:

Traceback (most recent call last):
  File "/Users/nomargfan661/Desktop/PythonProjects/chapter3/graphics.py", line 3

    from matplotlib.cbook import _string_to_bool, mplDeprecation
ImportError: cannot import name _string_to_bool

With this program, I am just trying to plot data points as written in a 
textbook from which I am learning.  I have installed everything properly 
(Python, VPython, numpy, and matplotlib (and as a result, pyplot).  The program 
is:

from __future__ import division,print_function

from pylab import plot,show
y = [1.0,2.4,1.7,0.3,0.6,1.8]

plot(y)
show()

I am running Python 2.7 and all modules are compatible with version 2.7 on Mac 
OS X 10.10.  I have tested other programs I have written which use VPython and 
numpy and I have no problems with those.  I only have one program using 
matplotlib, though, so I don’t know what’s wrong.  Would anybody happen to know 
how to help with fixing this issue?

Thanks,
Brandon
