Public bug reported:
Binary package hint: python-chaco
I am trying to use Enthought Chaco under Ubuntu but nothing works. From
all the examples in the /usr/share/doc/python-chaco/examples/ directory
only one (simple_polar.py) works. All others have unmet module
requirements, give errors and lots of deprecation warnings.
Versions (all from the Ubuntu repositories):
* Xubuntu 9.10 (Karmic Koala)
* python-chaco 3.1.0-1
* python2.6 2.6.4-0ubuntu3
Examples of unmet module requirements:
* from scipy.special import jn
ImportError: No module named scipy.special
* from pyparsing import (Literal, Word, CaselessLiteral,
ImportError: No module named pyparsing
* from configobj import ConfigObj
ImportError: No module named configobj
(python-scipy should probably be at least a recommended dependency.)
Minimal example that doesn't work (test.py):
from numpy import *
from enthought.chaco.shell import *
x = linspace(-2*pi, 2*pi, 100)
y = sin(x)
plot(x, y, 'r-')
title("First plot")
ytitle("sin(x)")
show()
This gives similar errors to examples above:
