OK, but right now MPL is broken with my version of wxversion, which is the
one shipped by default in Ubuntu. So it is broken for a lot of user.
It seems wrong for me to require the users to upgrade wxversion while
there is a solution that works, eventhough it may not be exactly what you
want.
One solution is to do bugware with hasattr(wxversion, 'AlreadyImportedError')

I think this is a little cleaner. More diagnostic information could still be added to the exception messages if this is going to be a continuing problem. Eric

It seems to work for me in all the configurations I can think of (and does raises the error when 2.6 is imported instead of 2.8.). I could be forgetting configurations, as the combinatory is high. These things are hard problems, thanks for your work. Gaël

Are you sure? Could you be pulling in some other wxversion? The only
other person reporting this problem so far is Tony Yu. I am now on
jaunty, and my wxversion has AlreadyImportedError. What version of
ubuntu are you using, and what is the full wx version that it includes?

The solution you propose doesn't work. It completely defeats the
version check.

Committed to svn. Please check it.

Ha, interesting:
$ ipython
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
Type "copyright", "credits" or "license" for more information.
IPython 0.10.bzr.r1163 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.
In [1]: import wxversion
In [2]: wxversion.__file__
Out[2]: '/usr/lib/python2.6/dist-packages/wx-2.6-gtk2-unicode/wxversion.pyc'
So, if wx2.6 is installed (I have 2.8 installed too), we run into these
problem.
Also, it is interesting to see that the older wxversion gets imported.
That does defeat the purpose of wxversion :). It means that you can't
have multiple versions of wx installed.

In a way it does. So we can add a check:
"if 'wx' in sys.module:"
to replace the "AlreadyImportedError", it is clearly bug ware.

Certainly does work betters. Also, the "AlreadyImported" problem is
caught elsewhere if I preimport an older version of wx:

25, in pylab_setup

File

line 137, in <module>
raise ImportError(missingwx)
ImportError: Matplotlib backend_wx and backend_wxagg require wxPython >=2.8
Thanks for your fix.

Actually, I beg your pardon, but it does not really work: if you have
2.6 and 2.8 installed, it will still import 2.6, which is not what you
want.
Here is a patch that works a bit better: it does import 2.8 even when 2.6
is installed:

I use wx a lot, and with MPL embedded in other programs, so I am a good test bed, and will hopefully catch major problems. However, I of course cover only the configurations I have installed on the various boxes I work on. One of the really nice things with MPL, is that there is a significant user base working from SVN, and thus catching problems early. Gaël

I just updated mpl from svn and now get y:126: UserWarning: Update your wxversion.py to one including AlreadyImportedError "Update your wxversion.py to one including AlreadyImportedError") backend WXAgg version 2.8.3.0 If I can speak for the typical user, these kinds of warnings are usually annoying and not that helpful.
