[Matplotlib-users] py2exe and jp windows

[matthew a. <ma...@ca...>]

Hi,

I thought I'd mention some small isuues I found with using py2exe to 
deploy matplotlib 0.63.2 on Japanese Windows 2000.

* pytz seems to need a copy of 
C:\Python23\Lib\site-packages\pytz\zoneinfo in the installed folder, 
otherwise it gives a KeyError on UTC when matplotlib is imported

* pygtk.require() is not compatible with py2exe, so I added a wrapper to 
backend_gtk.py to check for freezing:

if not hasattr(sys, 'frozen'):
     try:
          # Don't want to check this for py2exe
          import pygtk
          pygtk.require('2.0')
     except:
         print sys.exc_info()[1]
         raise SystemExit('PyGTK version 1.99.16 or greater is required 
to run the GTK/GTKAgg Matplotlib backend')

* font_manager.py throws an exception, I suspect to do with Japanese 
font names or font directory names:

File "c:＼Python23＼lib＼site-packages＼matplotlib＼font_manager.py", 
line 111, in
win32InstalledFonts
     key, direc, any = _winreg.EnumValue( local, j)
WindowsError: [Errno 234]

from this site:

http://www.google.com.au/search?q=cache:B8BlgKwVYxcJ:www.cubelab.com/ymasuda/python/index_jp.html+matplotlib+local+None+windowserror&hl=en

I found a workaround to add

local = None

at line 107 of font_manager.py to give this:

     for fontdir in MSFontDirectories:
         try:
             local = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, fontdir)
         except OSError:
             continue

         local = None

         if not local:
             return glob.glob(os.path.join(directory, '*.'+fontext))

* gtk 2.2.? was crashing (segfault) on Japanese Win2k so I upgraded to 
the latest (2.4.13) and now it seems to work. However now I get various 
dprecation warnings about the GTK toolbar when I show a plot. And 
IPython seems to break with GTK 2.4.x.

* Generally getting it all to work required quite a bit of fiddling and 
munging various recipes I found on email lists and in the pygtk FAQ. 
This included copying the matplotlib shared data into the installation 
and experimenting with different locations for it, and copying the gtk 
runtime into the installation and modifying the path within python so it 
could be found.

Thanks for matplotlib!

Cheers,
Matthew.
