[Matplotlib-users] multiarray.so import issues

[Sandy Oz]

  Hello everyone,

I'm trying to build a distribution directory for a wxpython 
app that integrates matplotlib.
I want to give the user all the packages that he/she needs 
without them having to install anything.
I was able to do this successfully on windows by using py2exe.
However, when on Unix I have ran into trouble.
When I try to include the numpy package, I get the following 
ImportError:

multiarray.so: undefined symbol: _Py_ascii_whitespace

It seems that this symbol is defined in unicodeobject.h but 
I could be wrong.
Is there I library I should include or am I missing 
something else.

Thanks for you help,
Sandy

PS. I'm setting up the distribution on an Ubuntu 10.10 machine.
I have Python2.6 installed as well as the latest versions of 
all packages (matplotlib,numpy).
The distribution package I'm building should run with python2.5

[Matplotlib-users] Destroying canvas

[Sandy Oz]

Hello everyone,

I'm building and application which will display a collection 
of several wxpanels each of which displays a 
FigureCanvasWxAgg with a particular subplot.
The user is allowed to remove these panels.
However, after a panel is deleted (call wxPanel.Destroy()), 
and the mouse moves over the now empty space, I get the 
following exception:
   File 
"/usr/lib/pymodules/python2.6/matplotlib/backends/backend_wx.py", 
line 1316, in _onMotion
 FigureCanvasBase.motion_notify_event(self, x, y, 
guiEvent=evt)
   File 
"/usr/lib/pymodules/python2.6/matplotlib/backend_bases.py", 
line 1244, in motion_notify_event
 guiEvent=guiEvent)
   File 
"/usr/lib/pymodules/python2.6/matplotlib/backend_bases.py", 
line 899, in __init__
 LocationEvent.__init__(self, name, canvas, x, y, 
guiEvent=guiEvent)
   File 
"/usr/lib/pymodules/python2.6/matplotlib/backend_bases.py", 
line 817, in __init__
 self._update_enter_leave()
   File 
"/usr/lib/pymodules/python2.6/matplotlib/backend_bases.py", 
line 844, in _update_enter_leave
 last.canvas.callbacks.process('axes_leave_event', last)
   File 
"/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", 
line 14586, in __getattr__
 raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the 
FigureCanvasWxAgg object has been deleted, attribute access 
no longer allowed.

Looks like the deleted canvas is still listening for mouse 
move events.
How can I prevent this?

Thank you,
Sandy
