py2exe and matplotlib errors when executing exe

Hi All,

I hope someone can help, I have run into a few problems when trying to
execute an exe file created when I use py2exe with matplotlib.
I have python2.5, matplotlib v0.99.1 and py2exe from GUI2Exe v0.5.0
optimisation is python -OO
the files compile correctly however when I execute the exe I get an error as
shown below
this is an extract

  File "matplotlib\mlab.pyo", line 380, in <module>
TypeError: unsupported operand type(s) for %: 'NoneType' and 'dict'

the traceback points to this line of my code

from matplotlib.backends.backend_wxagg import NavigationToolbar2WxAgg

does anyone know how to solve this, i have seen references made to numpy but
not matplotlib

Regards

Marco

This is probably the docstring problem mentioned at the bottom of <http://www.py2exe.org/index.cgi/MatPlotLib>.

Thanks, must have skipped over that one - I added the statements and it has
fixed it :slight_smile: however now there is an issue elsewhere. I get the message

  File "matplotlib\backends\__init__.pyo", line 25, in pylab_setup
ImportError: No module named backend_tkagg

and the traceback call this

from pylab import *

I have _tkagg as an exclude

looks like somebody else had this problem but nobody solved it
http://mail.scipy.org/pipermail/scipy-user/2005-July/004777.html

any one know how to solve this?

I tried to include matplotlib.backends.backend_tkagg, then this popped up
with a tkinter import error.

It should only try to import that backend when configured to do so. You may need to change your matplotlibrc to point to your desired backend.

Thanks, I changed the matplotlibrc file to use the WXAgg backend and then had
to copy the file into the mpl.get_configdir() and in my local working dir
for it to work.

The file runs however a python error screen pops up and then closes without
giving me the chance to read it, anybody know how to stop the window from
closing so quickly

Thanks

You have probably set "wx.App(redirect=True)", change to "False" and then you should see the exception in your IDE.
