#86678 — Question about python package numpy

Hi,

It is difficult to install numpy package for my PC Windows 7, 64-bit OS. In
the end, I install Enthought Canopy, which is recommended on line because it 
does install numpy automatically. Now, I can test it with

import numpy

it succeeds. On http://wiki.scipy.org/Cookbook, it shows some interesting
code example snippet, such as Cookbook / ParticleFilter, Markov chain etc.

I don't know how I can access these code examples, because I don't know where
Enthought Canopy installs these package.

Could you help me on using numpy examples?


Thanks,

Did you check Canopy's documentation?

Are you sure the examples in cookbook are installed with the package?
You can print numpy.__file__ to know where the package is installed.

At [1] I see "You can get the source code for this tutorial here: 
tandemqueue.py" with link to the file, why don't you get the source 
files for the example from their pages?

Thanks for your reply. I learned Python for about one week ago. The link 
in your reply does look like executable. But the second snippet about 
particle filter, see below please, looks award. i.e. I do not see the 
connection between the first and the second code snippet. I should save
them to one .py file? Or save to two files? What name should be for the
second file?


Thanks again.

None of these examples come prepackaged in any distribution I am aware of. You 
are intended to copy-and-paste them from the wiki if you want to use them.
