It is hard to guess what exactly your problem is as you do not  
provide a code
example or the traceback call of your exception. I would venture that  
you are
trying to create a num_array without having Numerix, numpy or  
numarray  imported
or installed on your machine.

Some more information about your troubles would be needed to really  
help you out.

Cheers

Hi all,
I have a python application that uses matplotlib.I am trying to compile it
into an executable using py2exe. I am encountering "No module named
num_array problem".  I do not know how to resolve this. I notice that "
matplotlib.numerix" is in the included package. Did you encounter this
problem. I am very new to this and I have to get it done by tomm. So I am
sorry if it is really silly.

Thanks,

Archana.

I am using matplotlib (currently 0.90) with wxPython and py2exe
(0.6.6).  Attached are some sample files.

I am on:
# Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)]
# wxPython 2.8.1.1, Boa Constructor 0.5.2

And as I am still using wxPython Ansi I renamed

matplotlib/backends/_wxagg.pyd

to

matplotlib/backends/_wxagg not used.pyd

Hope this helps

Hi all,

I have a python application that uses matplotlib. I want to compile it into

Thanks,

As for a good IDE. I really like eclipse with pydev.  For easy 
student/beginner setup, easyclipse has a nice python eclipse distribution

http://www.easyeclipse.org/site/distributions/index.html

I think I've tried near every python IDE setup out there over the last 
couple years, and this one wins for me.

I would have to agree with most of what Massimo said. 
When I started using matplotlib I also learned some
wxPython stuff because I thought that was needed.  Not
a bad thing to learn, but then all the pylab
references confused me.  Finally, I got it straight
and almost always start with import pylab now.  I
suspect matplotlib started out with the dream of
replacing some part of MatLab, but then morphed into a
nice plotting library for Python.  The documentation
has not shaken off that dream.  

Certainly, using pylab/matplotlib, iPython, and SciPy
one can go vary far in getting MatLab-like
environment.  But that combination (or something
similar) is needed beyond matplotlib.

Massimo is right, the real gain is Python in
combination with nice usable libraries for
scientific/technical programming.  Don't confuse the
newbies.

You are not mistaken, and this is by design: ipython is not an IDE,
it's the interactive component of a python workflow.

As others have mentioned (thanks to all, btw), it has limited support
for specifying your editor and a special command called %edit.  Many
people find this very useful, which is why I added it.  Personally I
don't use that at all.  My workflow consists of an open Emacs session
(with multiple frames, typically) and a terminal with ipython in it.
I do the heavy-duty editing in Emacs (replace with vi, IDLE, Komodo or
any other editor of your preference), save, and then run the code in
the terminal via

run filename

Since ipython has history that backtracks on what you've typed so far,
this normally just requires typing 'r' and then 'up-arrow' once.  I
personally don't find it any more cumbersome than hitting some F-key
in an IDE, and I get the power of Emacs with the comfort of a good
terminal (Konsole in my case).

Others have mentioned how ipython can also be used *inside* emacs,
which can be very handy for complex debugging.  It's not my daily
environment because I prefer Konsole to the emacs terminal, but it is
certainly a good way to work for many.

IPython comes from the Unix tradition of 'do one thing well and let
users work whichever way they want' rather than the windows approach
of 'provide a single, fully integrated mega-app'.  So it is easy to
use ipython with your personal combination of editor and terminal
emulator, but it does NOT provide the kind of IDE feel many expect
these days.  Whether this particular balance is a feature or a
drawback is largely dependent on personal preference, I think.

We are currently refactoring ipython in a way that will make it very
easy to embed all of its functionality into the terminal component of
an IDE.  So hopefully in the future, this discussion won't have to
happen: I'll be able to use ipython the way I do today, but it will
become possible for IDE authors to incorporate it in their own
environments.

Until then, it's worth understanding the pros and cons of using
ipython so you can decide whether you find its approach comfortable
for your style.

f

I always thought that the focus of matplotlib towards matlab-like 
interactivity is fundamentally flawed. Matlab-like interactivity is damn 
good when it is needed, but for that purpose in the free world there are 
already the good Octave, Gnuplot and Scilab.

The big strength of matplotlib is that it is Python -that is, it is 
built on top of a general purpose language that is both very powerful 
and a breeze to code with.

I would like to see matplotlib being pushed as a scientific plotting 
development library and environment, with pylab being a nice add-on for 
people accustomed with python and wanting a python-friendly interactive 
plot. Today matplotlib is marketed viceversa, and in my opinion this 
confuses newcomers (that see a programming language being used as an 
interactive command line environment) and doesn't help who wants to use 
matplotlib as what it is -a python library- with full power (I was 
*extremly* confused when I started to dig matplotlib to build a wx 
application and *everything* I found starting with was a reference to 
pylab...)

So, coming back to Giorgio question, I'd like to advice him to teach 
matplotlib+scipy to his students as a programming environment first, 
letting them learn Python, and *after* showing them that there is a 
pythonic interactive environment.

You can run ipython _from_ emacs. Needs a bit of messing about with
your .emacs, but once you've set it up, it works very well. Object
introspection and the debugger are very nice; you can execute code
fragments etc. Not quite a 'development environment', but a long way
towards one.

It explains how to do set it up in the ipython manual.

Mark,

you can set ipython (in the ipythonrc.ini) to start up the editor of your
choice when you type "edit" in the ipython-shell.

Check out this video at ShowMeDo, that shows a lot of the features of
ipython:

Oh, I see. You probably want an development
envirnoment.  Sorry.  IPython is great for
interactively running code, but not too great for any
editing.  I do my editing in a separate source-code
editor (BBEdit on the Mac).  That works well for me
since the editor can also run Python scripts in a
Terminal window.  There are some other products out
there (although I haven't tried them).  Two that come
to mind are SPE (I think that's the name) and Wings, a
commercial product that gets a lot of praise.   Give
them a look.

Oh, ok, checked better your email and that email -no big difference.
Basically the problem seems to be in the order you are building the 
packages, or in version (in)compatibility.

Are you sure that you are always using the same order? I find quite odd 
you install matplotlib *before* scipy -it should be the contrary.

Are you sure these are the same packages compiled in the same way from 
the same source?

That doesn't seem to be the case - it returns the right thing on the
first call - i.e. region got changed, but on subsequent calls the
figure is displayed and the function returns array([0,0,0,0]). I
thought taking the slice just gave access to the internals of region
...

How does one assign a new value to a variable in a containing scope?

Giorgio -

Thanks for starting this discussion and sorry for the late reply.
Use of Python with matplotlib in the classroom and by students in general is
a major objective of mine.

I use IDLE with numpy, scipy, and matplotlib.

The IDLE problem is really annoying though. Starting with -n is required (a
strange hack for many students), and then you cannot restart the
interpreter.
I keep hoping that the IDLE developers will be able to change the code such
that this is not necessary anymore.

Another difficulty is that it is cumbersome to change directories. In that
respect, it would be great if pylab had a change directory (cd) command.
That would make interactive use a lot easier. This could also be an IDLE
feature of course.

Another question I get from matlab users is why there isn't a 'whos' to
figure out all the variables that are used. This is really an interactive
issue, where the IDLE would be used as an interpreter (calculator really),
not as a means to develop serious code.

So to summarize, I think getting matlab users switched over, I see the
following three issues high on the list:
1. Get rid of the -n problem for running matplotlib interactively.
2. Make an easy cd command.
3. Make an who option.

On the bright side, I get quite a few people converted that don't want to go
back anymore....

indebted we are to Matplotlib. In my defense and to mpl's credit, using
it to generate the graphs has been so smooth that we barely know it's
there! 

Matplotlib processes data for more than 620 companies on the Australian
stock exchange after every trading day, producing more than 55,000
graphs per day. Several months ago I had a number of machines running
the graph generation on more than 3 years of historic data 24x7 for 
around 2.5 weeks, resulting in over 250GB of graphs, i.e >40 million!!

The site is very information rich and mpl is a mainstay of the
presentation of that information (see
http://www.marketshares.com.au/companies/20070301/profile/performance/CBA
for a sample). 

Kudos to John and all others involved in producing a fantastic open
source product!

Not sure what region[:] is supposed to achieve.  You are creating a copy 
with the same name, so you are over-riding the original variable.





Hi there

I have a function where I want to display an image, get the user to
zoom in on a region of interest, and then return the axes limits.

But the problem is, I can only use it once, the second time it gets
called in a script the figure doesn't appear. I know this is to do
with show() not being supposed to be used multiple times, but I don't
know what I should be doing instead ... any tips? (I'm still new to
python btw)

Also, if there's a better (more pythonic way) to do what I'm doing, I
would appreciate your input. I'm not sure if what I'm doing with the
region variable is dodgy or not.

Currently, I'm doing this:

from pylab import *

def getroi(im):
    imshow(im)
    title('Zoom in to region of interest, then press a key')
    region = array([0, 0, 0, 0]) # Placeholder values

    def keypressed(event):
        region[:] = [round(i) for i in gca().axis()]
        close(gcf())

    # Connect keypressed to event handler
    connect('key_press_event', keypressed)

    show()
    return region



thanks,

Richard
