After installing numpy, scipy, and matplotlib for python 2.6 and
running the code from http://www.scipy.org/Cookbook/OptimizationDemo1
(stored as xoptimize.py) in a directory with other python codes, I got
the error messages
C:\python\code\mycode>python xoptimize.py
Traceback (most recent call last):
File "xoptimize.py", line 3, in <module>
from pylab import *
File "c:\python26\lib\site-packages\pylab.py", line 1, in <module>
from matplotlib.pylab import *

File "C:\python\code\mycode\RandomArray.py", line 1, in <module>

ImportError: No module named ranlib
When I create a new directory, copy xoptimize.py there, and run, the
program works. Can someone explain why other files are "interfering"
in the first case? Thanks.
