I too am having a trouble getting GnuPlot to work with python. I have vista and have installed Numpy and GnuPlot. I have placed the gnuplot.py in the site packages folder along with GnuPlot and Numpy. When I try and run the gnuplot.py demo it says that there is no module Numeric. I found some help site that said that if Numpy is installed correctly you should be able to import Numeric.

Is there anything else you need to know?

A test of your NumPy installation would be:

>>> from numpy import oldnumeric

I know that I have Numeric and NumPy both installed on my system so that I never run into this problem. You can get Numeric on SourceForge.
SciPy has also proven to be invaluable.

I should also ask which OS you are on as there could be installation issues that we can look at in that light.

I have Vista and Python 2.5 installed, which when I tried to install Numeric it says it needs 2.4 to work and I couldn't find a version that worked with 2.5

Yep. That's why I asked.

Current officially released version is gnuplot 4.2.2
(released on September 1, 2007).
But # Gnuplot.py version 1.7 released 2003-10-19

My connection's the pits at the moment. I'll check out that for you. You may also want to check out matplotlib.

yeah i have those two versions.
also, i tried using that code they have with numpy to update from numeric but that didn't seem to work, but I doubt i was using it correctly.

I haven't had a chance to try this yet, but wanted to see some progress. Have you tried modifying the source code of the gnuplot library thusly:

>>> from numpy import oldnumeric as Numeric

Numeric may be imported in more that one place it the package, so I may need to come up with a better fix (like creating a new init.py for the package).

I just found some interesting links for you:Numericix for starters.

I looked at that site but was confused as to what I am supposed to be looking for.

also I tried the above fix and this message then popped up and confused me even more.

>>> C:\Program Files\Python25\Lib\site-packages\gnuplot-py-1.7\demo.py:50: Warning: 'with' will become a reserved keyword in Python 2.6
Traceback (most recent call last):

ImportError: No module named Gnuplot

The best solution that I have at the moment is that you install Python 2.4.4 (I have both that and 2.5 installed on system and use 2.4 for just this type of scenario).

alright, well thank you for your help

[bartonc]

alright, well thank you for your help

I think that I've found the answer to this.
In modules that depend on numeric, change the line

import numeric

to

from numpy.core import numeric

[bartonc]

This seems to work well and doesn't require original source code mods:

In your site-packages directory, create a file called "Numeric.py" (remember that python IS case sensitive). Two lines in that file should be all it takes to allow importers of the Numeric package to function properly:

from numpy import oldnumeric
globals().update(oldnumeric.__dict__)

To test this I used

import Numeric
help(Numeric)

Hi

The chances are that this is not to do with your numpy installation, but your environmental variables.

I'm afraid that I don't use windows anymore, but I remember there's a readme file in gnuplot.py that gives step-by-step for the set up, which involves fiddling with environmental variables and perhaps something else.

Apologies for the vagueness of the response. It's been a couple of years!
