That's in the _transforms module.  You might try with
matplotlib.use("Template") and see if it still crashes--not that I would

This is actually coming from ipython, not matplotlib.  This indicates 
that version of ipython you have installed was written for an earlier 
version of wxPython.  It may still work despite this warning.  (Maybe an 
ipython expert can comment on that.)  The current release of ipython 
(0.8.1) has been updated and does not present this warning with the 
current release of wxPython (2.8.4.0).

If both your ipython and wxPython are from official Fedora packages, 
that's a version mismatch, and should probably be reported as a 
packaging bug to Fedora.  You may want to upgrade ipython if you can do 
so easily.

That's very strange.  AFAIK, IPP is "Internet Printing Protocol", and 
this message usually comes from CUPS or something.  My best guess is 
that when wxPython initializes its first window, it also initializes the 
wxWidgets printing stuff, and there's something underlying that that is 
broken on your system.  (Only a guess).  Again, it's possible that 
things could continue normally despite this warning.

I would look into your printer configuration to see if these messages 
can be eliminated.

What are the error messages?  (Or do you just mean the ones above?)

I think if the plots being generated are okay, both of these warnings 
could be benign, though annoying.

No, thank you for trying so hard.

I just tried running setup.py with VERBOSE=True on a clean installation.
when it crashes I get:
LazyValue::init_type

does this mean anything to anyone?

It's probably something in C++ backend code for Agg.  Maybe someone else 
on this list knows the last time it built and worked on Windows and can 
track down a change that may have broken it.

It will probably take some work with a debugger to figure out where it 
is crashing.  I'd be completely guessing at this point.  If you feel 
adventurous and can get a C backtrace out of the crash somehow, (does 
gdb work with mingw?), that could be useful.  Barring that, maybe one of 
the other Windows folk on this list has some ideas.

Thanks for your considerable patience ;)

Cheers,
Mike

Dear all,

I'm an astronomy major college student in Beijing who recently switched to
Python for most of his homework in numeric analysis and data visualization
(and really loving Python). I run Python 2.5 with NumPy, SciPy
and matplotlib on a Fedora 7 Linux system. The matplotlib on my computer was
build from source but most of the required dependecies (incl. wxPython,
gtk2-devel things, etc.) were installed from the "official" Fedora
repository via yum. During compilation of matplotlib I set the BUILD_WXAGG
variable to 1 and left everything else untouched.

The compilation was smooth but the first test run seems not. After invoking
ipython with -pylab parameter I received the warning (and welcome) messages:

/usr/lib/python2.5/site-packages/IPython/Shell.py:709: DeprecationWarning:
The wxPython compatibility package is no longer automatically generated or
actively maintained. Please switch to the wx package as soon as possible.
import wxPython.wx as wx
Python 2.5 (r25:51908, Apr 10 2007, 10:29:13)
Type "copyright", "credits" or "license" for more information.

IPython 0.7.2 -- An enhanced Interactive Python.
? -> Introduction to IPython's features.
%magic -> Information about IPython's 'magic' % functions.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

Welcome to pylab, a matplotlib-based Python environment.
For more information, type 'help(pylab)'.

I don't understand what was said by the Deprecation Warning message. The
wxPython on my computer is up-to-date.

Then I threw a test command to ipython and things seem to be wrong again. A
typical session goes like this:

In [1]: # This is just a test plot. It generates a figure in the GUI with
some warning message.

In [2]: plot([1, 3, 8, 0])

** (python:15301): WARNING **: IPP request failed with status 1030

** (python:15301): WARNING **: IPP request failed with status 1030
Out[2]: [<matplotlib.lines.Line2D instance at 0x971648c>]

In [3]:


The correct figure was generated in a GUI but error messages pop
up whenever "plot" is used.

Currently I've got no idea about either warning message. They certainly told
me something but I can't even make sure whether there are things going
wrong! *shrug* So any hints?

Thanks in advance

Cong.

Yes.  It crashes at the savefig line.

Just to clarify, you mean the 0.90.1 installer downloaded from 
SourceForge?

Does it also crash if you use the Agg backend alone and save to an image 
file?

import matplotlib
matplotlib.use("Agg")
from pylab import *
plot([1,2,3])
savefig("test.png")

I also looked at the log_bar.py example and found that it's also at the
pylab.show() command that it dies

Ok--I reverted to head and it fixed the undefined references error and
everything seems to build normally.   But, if I try to run the
embedding_in_wx4.py example, it crashes python 2.5.1

If I install from the .msi then things do work in python 2.5.1, so it must
be something with the build.

I also tried to just start python from the command window, then ran:
import numpy as N
x=N.array([1,2,3])
from pylab import *
plot(x,x)
show()

The plot command generates a Line2D instance,
but the show() command kills python in the same way that the embedding
example does.  In the embedding example, I notice that the CanvasFrame is
generated before the crash.


Cheers,
William

I run from the command line.  Essentially, it just goes poof.  There is no
output--it generates an error report (as usual in windows)--but nothing pops
out that I can understand...

Now, it no longer gives rise to the previous error, but python crashes when
I run the embedding_in_wx4.py example.

I'm going to summarize, just to make sure I have everything straight.

1) HEAD doesn't build (you get lots of "undefined reference to 
`_imp__FT_Done_FreeType'")
2) revision 3645 (yesterday before my setup.py changes), builds, but you 
got the float('inf') error (which is now fixed)
3) much earlier revisions (3608) have other issues (which seem to be 
related to out-of-date wxPython code)

I have just committed a possible fix for 1).  You may want to try 
updating to HEAD and building that.

If that doesn't work for you, I'm worried about things getting out of 
hand and annoying a lot of people with my (well intentioned) setup.py 
changes yesterday.  If that's the case, I will revert my build changes 
until I have a chance to sit in front of a Windows box and figure out 
what's really going wrong.

Apologies all around,
Mike

3608 also runs into problems of linking with the freetype libraries.  Some
much older versions (say in the 3500s) compile, but still crash
python2.5.1with errors like:

C:\matplotlib\trunk\matplotlib\examples>c:\python25\python.exe
embedding_in_wx4.
py
embedding_in_wx4.py:24: DeprecationWarning: The wxPython compatibility
package i
s no longer automatically generated or actively maintained.  Please switch
to th
e wx package as soon as possible.
  from wxPython.wx import *

Thanks again for the help!

The call to "float('inf')", since it's in a default argument spec, will 
get called at import time.  Most (maybe all) of the backends import 
mathtext unconditionally, so this will get run whether mathtext is 
used/called or not.

I'm not opposed to importing mathtext on demand only, but that would be new.

Mike

I see, it wasn't clear to me on my first look that the bug was
triggered at module load time.  I had assumed the bug was triggered by
*using* mathtext.  Since you seem to have found the fix (numpy.inf)
I'm happy to leave it as is.

JDH

Do you get any output (e.g. a traceback) or it just goes poof?  (You may 
need to run it from the command line if you aren't already).

Mike

It's not clear to me why you should be hitting mathtext at all, since
the wxcursor_demo.py does not use it, as far as I can tell.  Michael,
would any of your earlier work caused him to get into mathtext
inapproriately?  You may need to revert a little farther, William, eg
to r3608 while we get this sorted out.

Did you report that error earlier?  Sorry I missed it.

It turns out that "float('inf')" is not portable to Windows.  See here: 
http://www.python.org/dev/peps/pep-0754/

I just committed a possible fix using numpy.inf instead.  Please update

   lib/matplotlib/mathtext.py

and let me know if this works (again, sorry I don't have Windows to test 
on here.)

In the meantime, I'll try to track down why the build is broken on trunk 
for you.

Cheers,
Mike

If I revert back to 3645, it builds and I can install it--but then I run
into
the original error I was having where I couldn't run the demos:
