I'm just getting into matplotlib and python. My apologies if I just
haven't found the obvious documentation.
I am running XP/Enthought Python 2.5/Idle/matplotlib 0.98.5.2
I run one of the scripts from the tutorial:
import numpy as np
import matplotlib.pyplot as plt
mu, sigma = 100, 15
x = mu + sigma * np.random.randn(10000)
# the histogram of the data
n, bins, patches = plt.hist(x, 50, normed=1, facecolor='g',
alpha=0.75)
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title('Histogram of IQ')
plt.text(60, .025, r'$\mu=100,\ \sigma=15$')
plt.axis([40, 160, 0, 0.03])
plt.grid(True)
plt.show()
A window with the figure appears on my screen. It looks very nice. But
now my PYTHON-Shell screen is dead.
I can go to the figure window. I right click on the upper-border to
close the window. I get the following error message on the
PYTHON-Shell.
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python25\lib\lib-tk\Tkinter.py", line 1403, in
__call__
return self.func(*args)
File "C:\Python25\lib\idlelib\MultiCall.py", line 151, in
handler
r = l[i](event)
File "C:\Python25\lib\idlelib\ScriptBinding.py", line 166, in
run_module_event
interp.runcode(code)
File "C:\Python25\lib\idlelib\PyShell.py", line 701, in
runcode
self.interp.restart_subprocess()
AttributeError: ModifiedInterpreter instance has no attribute
'interp'
And the shell-window is still dead. I can't do anything else until I
close all my Python windows.
Is there a better way to close the figure-window?
Should I expect IDLE to work with matplotlib? Should I try and figure
out Ipython instead?
Should I look for a Tkinter installation? My current version is
Revision: 50704?
Any help or suggestions are appreciated.

I have the vague remembrance of the fact that IDLE does not play well with matplotlib.

I have had similar experiences with IDLE on both XP and Ubuntu 8.04 and as a result I use IPython as much as possible. On XP I would recommend that you install Python(x,y), 2.1.9, http://www.pythonxy.com/foreword.php which includes IPython(0.9.1) and IDLE(1.2.2) as well as many other useful programs. The example you gave runs under IPython with the command run -i programname.py and gives a plot which can be accessed independently of the IPython shell. In other words you can execute commands in the shell while the plot is still on the screen. Hope this helps Richard p.s. I, like you, would still be interested in knowing why IDLE crashes when a .py script is run twice. Richard Johns rj...@tb...

I > will just have to learn how to be effective with ipython. This may be true that idle doesn't play well with mpl, but I don't know why it should be (it used to work ok). It is definitely in your interest to learn ipython (it's easy) but if you want to try idle, make sure you read http://matplotlib.sourceforge.net/users/shell.html Also, when this came up in the past, people suggested to run idle with -n and set the os.environ['PYTHONINSPECT'] = '1' evnironment variable, eg http://mail.python.org/pipermail/edu-sig/2005-January/004362.html |

The full edition of Python(x,y) 2.1.9 contains all of the software you mentioned(PIL, matplotlib, IPython, Enthought Tool Suite) while any of these missing from the basic and light editions can be added as plugins.

Enthought Python includes a lot more pre-packaged Python libraries than Python(x,y) -- for example, the wxPython GUI library (unfortunately, in my surely biased opinion, the developers of Python(x,y) did not include wxPython in their distribution), and MPL Basemap toolkit. > Another thing I like about Python(x,y) is that it is updated frequently > so that you are always working with the most up-to-date software without > having to compile it yourself. Well, none of these pre-packaged distribution is really "up-to-date", as the development versions of the libraries (those available only via svn) will of course never be included.
