Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...

[<kc1...@ya...>]

With Stef's help, I was able to get pass the
"Matplotlib datafile not found" problem in using
py2exe and Matplotlib under Python 2.3 - but then ran
into the same Tkinter not loaded problem like he did.

After reading Stef's messages from this list, I
downloaded the latest version of Matplotlib - only to
find that Python 2.3 is no longer supported.  So, I
loaded up Python 2.5 and ran the setup script for
Py2exe.  Now, py2exe is unable to find
wxmsw26uh_vc.dll - eventhough I have wxPython 2.8
installed.  So, I dug up a copy of wxPython 2.6 and
have that installed.  The file is now there but py2exe
still can't find it.

This is very fustrating!

So, do I understand this correctly:

In order to get rid of the Tkinter problem when
building a matplotlib application using py2exe, I need
0.91.2 ver of matplotlib and use the setup.cfg file to
select the backend I want (wxpython in my case).  Then
run py2exe to build the ap.  Correct?

But then, as I posted earlier, this create a new
problem for me in that py2exe says it can't find
wxmsw26uh_vc.dll - even though the file exists.

What I need is a version of 0.91.2 ver of matplotlib
that works with Python 2.3 to see if that works, or I
guess I would include Tkinter with my exe?

Do I understand all these correctly?

I might be misremembering, but I thought 0.91.2 worked with Python 2.3. 
  I don't use 2.3 every day, however.  Can you send the errors that are 
produced when you build or run matplotlib 0.91.2 with Python 2.3?  Or 
are you just referring to the fact that there are no Windows binaries 
provided for Python 2.3?

Mike

I haven't tried it with 0.91.x but with 0.90 I used a matplotlib exe
installer for Windows and I can create a distribution of my application
with py2exe which does NOT contain tkinter.

That dll should no longer be needed by matplotlib.  Obviously if you use
a wxPython build you will get the it, i.e. I am on 2.8 so I have a bunch
of  "wxmsw26uh???.dll" files in my dist folder.

There was another message from Stef which might be the explanation, the
default matplotlibrc file is defining TKAgg as the default backend, so
change it to the following:

backend      : WXAgg
numerix      : numpy  # numpy, Numeric or numarray

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...

Michael,

I am referring to the fact that there are no Windows
binaries provided for Python 2.3.  If I simply copy
the matplotlib directory over to Python23, py2exe will
get confused.

I have no clue how to build it for Python23.  I don't
even have any C compiler.

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...

[<kc1...@ya...>]

I *finally* got this to work!!!  

Thanks to Werner's message, I found the culpit:  the
matplotlibrc file copied to the dist directory
contains the TkAgg backend.  All I had to do is to
change *that* file to say:

backend      : WXAgg

Note that it's not the matplotlibrc in the installed
copy - but the one in the resulting dist directory.

In addition, I have to do a:

   set MATPLOTLIBDATA=.\mpl-data

before I start the exe file.  I don't know why this is
necessary because the code for _get_data_path appears
to look at that directory by default but if I don't
set this, it can't find the data files.

In any event, it works now - after bumping head for 2
weeks!

Thanks everybody.

You shouldn't need to do this.  Note in matplotlib.__init__.py, it looks 
at a different folder if it is frozen by py2exe or py2app or ...:
    # py2exe zips pure python, so still need special check
    if getattr(sys,'frozen',None):
        path = os.path.join(os.path.split(sys.path[0])[0], 'matplotlibdata')

So, if you use the sample setup.py I posted a while ago here and on the 
wxPython list it will create the matplotlibdata folder in your 
distribution (basically a copy of your mpl-data folder) folder.

Hope the wall wasn't to hard, I always try this or the wxPython list 
after a day or two ;-) .

See you

Re: [Matplotlib-users] MatPlotLib + Py2exe, backend problems ...

[<kc1...@ya...>]

Ok, I know what the problem is.  I was using a sample
setup.py posted by Stef and in his setup, he created a
"mpl-data" subdirectory under "dist" to store all of
the data files use by matplotlib.  That's why
matplotlib couldn't find it without a set statement. 
After changing the name to "matplotlibdata",
everything works.

I also made changes to every one of the matplotlibrc
file I found in the installed copy of matplotlib to
invoke WXAgg - instead of TkAgg.

So for completeless, may be this will benefit other
matplotlib users, here's my py2exe script - tested
using python 2.3, latest wxpython and so forth.

Let say you wish to create an exe of the sample
multicolor.py program.  Place multicolor.py in a
test\multicolor directory, and a copy of the following
script, have py2exe installed, and then just run it. 
You will end up with a dist subdirectory under
test\multicolor and that's where you'll find
multicolor.exe.

Here was the solution:
Ok I updated MatPlot from version from 0.87.7 to 0.91.2
