Why can't I use NumPy functions in Canopy's IPython?

Question

I am struggling to use basic NumPy functions in my Python programme on Enthought's IPython, such as 'pi' and 'logspace'

It also says that the term 'plot' is undefined - has it changed?

Thanks so much

Answer 1

Had you imported numpy and matplotlib? If I had to guess, you used to start ipython with the --pylab flag. That flag is the destroyer of minds and hearts, and was recently deprecated.

A more merciful approach would be explicit imports that maintain namespaces, i.e.,

import numpy as np
import matplotlib.pyplot as plt
%matplotlib inline

However, if you want the mayhem to continue, you can execute from pylab import * at the top of your notebook.
