[Matplotlib-users] while import always error

[Pujo A. <aj...@gm...>]

I found this error message when I import pylab.

from pylab import *

Error message:
Microsoft Visual C++ Runtime Library
Assertion failed!
Program:c\python24\python.exe
File:CXX/cxx_extentions.cxx
Line:1031

Expression: ob_refcnt =3D=3D 0
For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts

First I install in new computer python 2.4.1
then the error comes out.

So I tried to reinstall with python 2.4
The problem still comes.

Please help

Hmm, that's a strange one.  We've seen this once before

http://sourceforge.net/mailarchive/message.php?msg_id=3D8789882

and I can't remember what the solution was (the thread doesn't mention
it) but it was resolved.  I've CCd Gregory on this email to see if he
can remember, since he once saw the same problem .

Are you using the python from python.org?  Does it help if you remove
site-packages/matplotlib and then reinstall?  Please create this
simple test script

  import pylab
  pylab.plot([1,2,3])
  pylab.show()

and run it with

> c:\python24\python myscript.py --verbose-helpful

and paste in all the output and errors in your response after doing a
clean reinstall, as well as your OS information ....

I use python org. I already uninstalled the matplotlib from windows
add/remove program and verify that no matplotlib directory in
site-packages.
After that I reinstall the matplotlib again I use version 0.80

I can't import the matplotlib even in the minimum condition.
For example I go to python shell and type import pylab, this raise the
same error.

I create your myscript.py and run it, but before it finished it shows
the same message in windows forms like I send before, and I have to
stop it.

This processed is stop because I have to cancel the program (due to
error message I sent).

D:\>python myscript.py --verbose-helpful
matplotlib data path c:\python24\share\matplotlib
loaded rc file c:\python24\share\matplotlib\.matplotlibrc
matplotlib version 0.80
verbose.level helpful
interactive is False
platform is win32
numerix Numeric 23.8
font search path ['c:\\python24\\share\\matplotlib']

my os is Windows XP Home Edition.
