missing mpl.data?

Community matplotlib-users
1

I have built some matplotlib installers for OSX, but some users are running into problems running them afterwards:

>>> from pylab import *
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2 .4/site-packages/pylab.py", line 1, in ?
     from matplotlib.pylab import *
   File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/matplotlib/__i nit__.py", line 620, in ?
     defaultParams = {
   File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/matplotlib/__i nit__.py", line 266, in wrapper
     ret = func(*args, **kwargs)
   File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/matplotlib/__i nit__.py", line 427, in _get_data_path
     raise RuntimeError('Could not find the matplotlib data files')
RuntimeError: Could not find the matplotlib data files

It appears that the mpl.fata subdirectory is missing; is there any way of ensuring that everything is included in the installer?

Thanks,
C.

With the new setuptools support it is assumed that if you have
setuptools installed, you are going to use it. Hence, if you run
bdist with setuptools installed, the mpl-data folder will get stuck in
the wrong place. You shouldn't be able to do the reverse since you
can't run bdist_egg without setuptools. In any case, the mpl-data
folder should ALWAYS be put inside the matplotlib module folder. This
is where it is found at runtime.

I've been working on this too. It's be nice if we coordinated our efforts, and got a single package up on pythonmac.org/packages.

The way I'm doing it, I'm statically linking libfreetype and libpng, so that we end up with a stand-along module that works on any OS-X (10.3 an above, anyway). I've made one for the Apple supplied 2.3 or the framework build 2.4.1.

It supports wx, tk, and Agg. It doesn't support GTK, because I don't know of a GTK package that is built outside of fink or darwinports.

Do you guys have similar goals? is it time to use Eggs? I have no particular desire to do this, but I do want a point+click installer that the folks I work with can use.

wx has always given me headaches, so I dont bother with it anymore. Since ActivePython 2.4.2 for Mac already comes with Tk, I just try and make sure it works for TkAgg.

I just need a portable matplotlib installer, as my MCMC module requires it. I have been generating eggs out of convenience, but I am not married to the format (in fact, I have been generating mpkg installers as well.

well, I need wx, so that's a given for me. I never use TK, but I want to support it.

Will the same package work for the ActivePython install as the "official unoffical" one, or do we need different installers? Also, does activestate provide a place to put packages built for their distro?

I've been doing only mpkg. What advantage do Eggs have? I kind of like using the native OS-X way -- users know what to do with them.

Have you had to do any hacks to the setup.py and friends?

What do you do with libpng and libfreetype?

I was maintaining mpkgs here,
http://sda.iu.edu/links.shtml?prim=lab_links, but they are a little
out of date. That and the are a pain to maintain. I have been
playing with eggs lately and prefer them. I include libpng and
freetype statically in the egg, and it seems to work for me. You can
check them out here, http://euclid.uits.iupui.edu/~cmoad/mpleggs/, if
you want.

I usually stick with Apple's bundled python. I also build for wx and
tk since both come with tiger. I don't really have a preference on
numerix.

Mine too. I almost got 0.85 built, and then you went and released 0.86!

Why's that? I do have a little patch to setup.py and friends to add the StaticLibs path, but that's it. I keep meaning to give that patch to John, but haven't gotten around to it.

Maybe it's time to look into that. How do you install an egg?

will do.

tk since both come with tiger.

Are you building Tiger only then? Damn, there are a lot of python+OS-X combinations to support! Also the wx version that comes with Tiger is pretty old, so I'm not sure how helpful that is. Boy, this is a pain!

I don't really have a preference on
numerix.

I try to support both Numeric and numarray, but I'll be adding numpy soon.

I really think the Python-OS-X community needs to have a fairly unified pile of packages to install. pythonmac.org is a good place for them, only because it's there. My goal is to have a MPL that works with the other packages there, so you can do one stop shopping. I'm running 10.3, so I currently build versions for Apple's 2.3 and Bob I's 2.4.1. Both of those have Numeric, numarray and wxPython packages on that site. Those need some updating, but they are there.

If the three of us could come up with a unified way to build these, and get that way into the official MPL setup.py, then it should be easy to maintain: download the latest tarball and run a script. (OK, then debug the problems, but what can you do?)

StaticLibs path, but that's it. I keep meaning to give that patch to
John, but haven't gotten around to it.

I was building against frameworks of libpng and freetype. It was the
more mac way of doing things, but took a little more effort.

Maybe it's time to look into that. How do you install an egg?

Once you install setuptools, there is a command line tool called
easy_install. Its name doesn't do it justice. You can pass easy
install a module name and it will look on the cheeseshop. You can
pass a source url and it will download, build, and install it. You
can pass it a local directory pointing to a source. You get the
pattern. It has a lot of logic built in and does the right thing 99%
of the time.

combinations to support! Also the wx version that comes with Tiger is

I don't have access to 10.3.

I am willing to help, but osx is not my primary/only target. This is
another reason I like eggs. They work great on osx/linux/windows.
