Thank you! Amazingly, all that worked first time - I certainly would not
have stumbled upon that solution on my own! Pip did the job, I did not
need to use a variant:
pip --version
pip 19.1.1

Sorry, that's with backslashes:

Hi David,
Does this simple code work?
import matplotlib.pyplot as plt
plt.plot([0, 1], [2, 3])
plt.show()
Indeed, it looks like matplotlib is not installed or not available for import
on your machine. SymPy relies on matplotlib for plotting (both are part of the
global SciPy project). However
I am puzzled as to whether 64 bit python under windows supports
plotting. Here is a typical experiment to obtain a plot:
import sympy
from sympy import *
var('x y')
plotting.plot3d((exp(-(x**2+y**2))),(x,-3,3),(y,-3,3))
Traceback (most recent call last):
