Thread: [Matplotlib-users] show() blocks script execution for TkAgg from ipython -pylab

I just upgraded my windows machine to matplotlib 1.0.0 and a simple
script such as

from pylab import *
from scipy import *

t = arange(0,1,0.01)
y = sin(2*pi*t)

figure(1)
clf()
plot(t,y)

show()

Now halts execution when run from the ipython -pylab prompt.  The same
commands typed at the commandline do not lead to show() halting
execution.

Is this expected behavior?

Thanks,

Ryan

This was fixed three weeks ago in svn, both the maintenance branch and 
the trunk.  I made some changes in show() shortly before 1.0, trying to 
get uniform and reasonable behavior in all backends, and I didn't quite 
succeed.  I think I got it all straightened out--but only after the 
release, unfortunately.  I hope it won't be too long before a 1.0.1 
bugfix release can be made, but I am aware of no schedule.

Thanks.

I need to role out a python install for my students.  Classes start in
a week and a half.  What should I do?  The installation for most of
them needs to be fairly simple.

Thanks,

Ryan

0.99.3 is more or less fine, but there is an annoying exception window
that pops up if you close IPython with a plot window open (using the
TkAgg backend).  But in my mind this is less bothersome than having to
close all the plot windows every time I run a script (I tend to write
scripts that generate 5-10 plots at a minimum).

If I could easily build an installer from svn, I would try it.  I
don't have any microsoft compilers installed on my windows computers.

Thanks again,

Ryan

Ryan: you could try matplotlib-1.0.0.svn.win32-py2.6.exe from 
http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib .It was built this 
morning from svn.
