PythonCard on OS X 10.4
by Arthur Elsenaar Aug. 25, 2005

Aug. 25, 2005

Hi, trying to install PythonCard on OS X 10.4, but running into an import problem. I installed python2.4.1, wxPython2.6, TigerPython24Fix and TigerPython23Compat from Bob's packages page and added /usr/local/bin to my path. Python2.4 runs fine and I can import wx fine, but not pythoncard.. anyone know what can be wrong? Thanks, Arthur.

SciPy installer for Panther Python, anyone?
by Just van Rossum Aug. 12, 2005

Aug. 12, 2005

I'd like to quickly evaluate SciPy for a project, but I can't seem to find a binary distribution for 10.3's Python anywhere. Am I not looking hard enough? Tried to build from the source but the amount of dependencies for building it makes this not a viable option right now. Just

memory allocation issue
by Chris Fonnesbeck Aug. 1, 2005

Aug. 1, 2005

I have a Bayesian simulation package, PyMC, that I run on OSX 10.4 using either Python 2.3.5 or the ActiveState 2.4. It essentially generates long sample arrays of parameter values, which it then summarizes at the end (I am using Numeric arrays). However, after a simulation of only 80K iterations (for about 7 parameters), I start running into memory allocation problems: python(22156,0xa000ef98) malloc: *** vm_allocate(size=1400324096) failed (error code=3) python(22156,0xa000ef98) malloc: *** error: can't allocate region python(22156,0xa000ef98) malloc: *** set a breakpoint in szone_error to debug Traceback (most recent call last): File "<stdin>", line 1, in ? File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/PyMC/MCMC.py", line 1768, in sample except KeyboardInterrupt: File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/PyMC/MCMC.py", line 1286, in summary } File "/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/PyMC/MCMC.py", line 260, in get_trace return array([x for i, x in enumerate(self._trace[start:end])]) MemoryError: can't allocate memory for array This doesnt seem like a lot of data, so I am wondering what the problem might be. Should I be using numarray instead -- it sounds like I would take a performance hit if I did. Any guidance here would be most helpful. Thanks, Chris

Problems with Notifications in PyObjC
by Jon Rosebaugh July 29, 2005

July 29, 2005

I hope this is an acceptable place for PyObjC problems... Anyhow, I have a small project I'm working on (zip available at http://li5-50.members.linode.com/~jon/NoteDB/NoteDB.zip), and notifications aren't working out for me. I think. I have a delegate for a NSTableView, and my tableViewSelectionDidChange_ method isn't being called, while other delegate methods are. I also have tried to subclass NSTableView, in accordance with the directions here (http://borkware.com/quickies/one?topic=NSTableView), but that subclass isn't receiving the textDidEndEditing_ notification either. Since the only things these have in common is that they are notifications, the only idea I have is that I'm neglecting something crucial for notifications, but the PyObjC docs don't indicate that I need to do anything special. Thanks in advance for any help. -- Bloggity: http://blog.inklesspen.com/

pyObjC examples pkg
by Jerome Lefebvre July 29, 2005

July 29, 2005

I just downloaded pyObjC 1.3.7 on a fresh installation of Tiger. I ran the mkpg, everything seemed fine but the examples didn't show up in a /Developer/Python/ as the docs said and spotlight couldn't find anything. So I ran the example pkg on it's own, but still nothing appeared. I poked in the info.plist of the example pkg and changed IFPkgFlagDefaultLocation from /Volumes/Data/Developer/Python/PyObjC/ Examples to /Developer/Python/PyObjC/Examples . Ran the example pkg and it now the examples were there and they builded/ran fine. Anybody have an idea of what could have happened here? Jerome

late start with tiger
by Scott Frankel July 28, 2005

July 28, 2005

I've just migrated a machine to Tiger and have a question about the "official unofficial" mac version of python.2.4.1. Why would /usr/bin/python still be linked to python2.3 after the install? I downloaded and installed MacPython 2.4.1 from undefined.org. I also downloaded and installed both TigerPython24Fix and TigerPython23Compat. If I execute python 2.4 using an explicit path to /Library/Frameworks/Python.framework/Versions/2.4/bin/python2.4, then python2.4 launches happily (with readlines!). But if I execute the python specified in my env (i.e.: /usr/bin/python), python2.3 launches due to the link. Thanks in advance! Scott

Hello; F2PY
by Andreas Voellmy July 28, 2005

July 28, 2005

Hello, I'm new to the list. I'm wondering if anyone on the list has any experience using f2py (http://cens.ioc.ee/projects/f2py2e/) on the mac os x? I would like to use it so that I can access functions written in fortran in python. I'm having trouble getting it working on tiger. I'm just working on the hello world example and haven't gotten it to compile correctly yet. gcc in mac os x apparently has the fortran compiler removed or turned off. So I am using a port of gfortran to compile my fortran. i've gotten f2py to compile a shared library using gfortran, but when I load it into python it has a fatal error and suggests that i may not have compiled the library under the right version. This makes sense. I compiled with gfortran, part of gcc 4.0, while python on my mac is compiled under gcc 3.4. I haven't yet been able to get around this issue. I'd love to hear from anyone who has experience with this topic. I can send more detailed info if anyone is interested. Thanks, Andreas

I thought it should work like this: > >ipe = app("System Events").processes['iPhoto'] >ipe.keystroke(u"foo") As Bob says, application commands can take a maximum of one direct parameter, and invoking a command on any reference other than app('...') tells appscript to use that reference as the direct parameter, hence the 'too many direct parameters' error in the above. (Suggestions for making error messages easier to understand arealways welcome , of course.) Anyway, appscript's help() system is your friend, although System Events' dictionary is a bit vague in this instance: Command: keystroke(...) -- cause the target process to behave as if keystrokes were entered Unicode -- The keystrokes to be sent. [using=k.command_down | k.control_down | k.option_down | k.shift_down] -- modifiers with which the keystrokes are to be entered The key phrase is 'target process'; which in GUI Scripting terms is the front process. And since the command doesn't take a reference to the target application's GUI objects, one can deduce that 'keystroke' should be called on System Events' app object, which will automatically pass those keystrokes to whatever application is frontmost at the time: app('iPhoto').activate() app('System Events').keystroke('foo') Sorted. Sherlock Holmes would've loved this stuff. :p has -- http://freespace.virgin.net/hamish.sanderson/

Appscript and keystrokes
by Nathaniel Gray July 27, 2005

July 27, 2005

I'm trying to use Appscript to send keystrokes to iPhoto (sadly, there's no other way to get the job done), but I can't figure out how to make it work. I thought it should work like this: ipe = app("System Events").processes['iPhoto'] ipe.keystroke(u"foo") But this yields the error: >>> ipe.keystroke(u"foo") ------------------------------------------------------------ Traceback (most recent call last): File "<stdin>", line 1, in ? File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/appscript/specifier.py", line 203, in __call__ raise CommandError(self, (args, kargs), e) CommandError: Too many direct parameters: command was called on a reference but already has a direct parameter. Failed command: app(u'/System/Library/CoreServices/System Events.app').processes['iPhoto'].keystroke(u'foo') Does anybody know the magic words? I'm using Tiger, Python 2.3 (stock), appscript 0.13.0.
