Hi I am trying to create an executable for a wxpython app that plots
some data using matplotlib , pyplot.figure().
I have tried following the directions for including the matplotlib
data files detailed here(http://www.py2exe.org/index.cgi/MatPlotLib)
but still get an error indicating that the data files are not bundled.
RuntimeError: Could not find matplotlib data files
#######################
Here is my setup_win.py
#######################
from distutils.core import setup
import py2exe
import matplotlib
from distutils.filelist import findall
import os
name = "CuppaTmGui.py"
DATA_FILES = matplotlib.get_py2exe_datafiles()
#DATA_FILES.append(r"C:\Python27_32\tcl\tcl8.5\init.tcl")
setup(console=['CuppaTmGui.py'], options = { "py2exe" : {"includes" :
["cuppa_tm","matplotlib.backends.backend_tkagg","numpy","pylab"],"skip_archive":0
, "bundle_files" : 1 }}, data_files = DATA_FILES)
I am wondering what I am doing wrong while packaging the executable.
I also tried to run with "bundle_files : 2" option or "bundle_files"
: 3 , but that results in an exe that immediately crashes and
triggers a miscrosoft error report.
I am building my exe using 32 bit python on a 64 bit windows machine.
Thanks for your help

Dear Michael,
Sorry for such a lengthy email, but I wanted to ask about dependencies
as well. I am trying to get python and py3k versions of matplotlib
working. In addition to this I am trying to do this with git/master
version. I can build Python2 version, but I could not do it with Python3.
Could you tell me which packages are indeed needed to build python
git/master? What are differences between Python2 and Python3
dependencies? I could later provide a patch for the git/master INSTALL
file.
So, the compile dependencies are as follows?
 media-libs/libpng # Needed?
 dev-python/imaging # Only for docs?
 dev-python/xlwt # What about this package?
Runtime dependencies?
 virtual/ttf-fonts # I guess theese are needed for selecting
 media-fonts/stix-fonts # different fonts, or is it the case that
 media-fonts/texcm-ttf # mpl uses LaTeX fonts already?
 dev-python/pyparsing # Necessary?
 cairo? ( dev-python/pycairo ) # What about pango?
 excel? ( dev-python/xlwt )
 latex? ( # Needed only for latex'ing
 virtual/latex-base
 app-text/ghostscript-gpl
 app-text/poppler[utils] # Needed?
 dev-texlive/texlive-fontsrecommended
 )"
I started to follow the development of MPL a bit and IIRC it is
now possible to install a python3 version along with the Python2. What
is more one can use Pyside instead of pyqt4 for qt. But what about gtk?
What libs are needed if I want to use gtk and python3? I remember, that
there were some issues, but do not know whether they were resolved.
Maybe it would be a good idea to reflect the Python3 status/dependencies
in the documentation?
Either way, thanks very much for working on the project!
All best,
Ignas A.

Just getting to this after some unexpected absences. Yes -- that is how 
symlog was originally intended, so there isn't currently any way to 
configure it. Please file the issue and assign it to me. I'll have a 
look at what needs to be added to support this.

Sure. I understand these are needed for both matplotlib itself and the 
docs. I still think there's some extras, though.

Great -- I didn't mean to imply you weren't still working on it ;) 
Thanks, as always, for all the work you've done on that.

Sorry -- I had misremembered. It's Qt and Wx that used to have C/C++ 
extensions that are no longer required. It seems we still need this for 
Gtk, so you're right -- this is a legitimate build dependency.

Nope. There is no Qt C++ extension anymore (hasn't been for years). 
The only dependency is on python-qt4, and only at runtime, not build 
time, technically.

Same issue as for Qt/Qt4 -- there's no C code that links to it.

Agreed. But why would anyone not want TeX installed? :)

David,
Thanks, that is much clearer what you are looking for. You are right, I
can't seem to find any sort of obvious way to get what you want. Reading
the docs for the SymLog scale indicates to me that the author intended for
the logrithmic portion to be most interesting and the linear portion was
only supposed to be a work-around the whole log(0) issue. Could you file
an issue on the github page so that we can mark it as a feature request?
Thanks,
Ben Root

Yeah, it definitely seems like there's a bit too much here. I think 
some of these dependencies are obsolete, in that we used to build 
extensions against gtk and wx in order to transfer image data to those 
backends, but those are no longer needed with current versions of those 
libraries.
I looked up the direct dependencies of the package (since I think many 
on the list you provided are probably secondary dependencies.) I have 
some comments below. Maybe Sandro Tosi, who I know has done some Debian 
packaging of matplotlib in the past, has some thoughts.
debhelper (>= 7) - probably needed to build a debian package
dvipng - to build the documentation
graphviz - to build the documentation
ipython - **seems unnecessary**
libfreetype6-dev - legit
libgtk2.0-dev - **no longer necessary**
libpng-dev - legit
python-all-dbg (>= 2.4.4-6) - **not strictly necessary, but helpful for debugging**
python-all-dev (>= 2.3.5-7) - legit
python-configobj - **necessary only for a long abandoned experimental version of matplotlib**
python-dateutil - legit
python-epydoc - **obsolete**
python-gtk2-dev - **obsolete**
python-imaging - legit
python-numpy (>= 1:1.3.0) - legit
python-numpy-dbg (>= 1:1.3.0) - legit

python-qt-dev - **obsolete**
python-setuptools - legit
python-sphinx (>= 0.5.1) - to build the documentation
python-support (>= 1.0.0) - not sure what this is
