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

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
