Dear ALL, I received a report of a Mac OS X user who attempted to run my recently released biodiversity mapping software based on MPL/Basemap and wxPython. As I have no access to an Apple Macintosh machine nor have much experience with that OS anyway, I am posting the error report here in the hope some of you nice guys can help. I am also posting the steps the user followed in order to install the software on the Mac OS X. From the error log, it looks that there may be some issue with the version fo MPL he is using (which is the one packaged with Enthought Python). Thanks in advance for any assistance you can provide. With best regards, ======================== Getting the package to work: 1. need networkx download .egg file from here: http://pypi.python.org/pypi/networkx/ install with: easy_install /Users/nick/Desktop/downloads/networkx-0.99-py2.5.egg (get easy_install from here: http://peak.telecommunity.com/DevCenter/EasyInstall#installing-easy-install http://peak.telecommunity.com/DevCenter/EasyInstall#downloading-and-installing-a-package ) 2. need mpl_toolkits.basemap: download source from here: http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792/&abmode=1 install instructions: http://matplotlib.sourceforge.net/basemap/doc/html/users/installing.html 2.1 - download & unpack cd /Users/nick/Desktop/downloads/basemap-0.99.3/ cd geos-2.2.3 export GEOS_DIR=/usr/local ./configure --prefix=$GEOS_DIR make sudo make install cd .. python setup.py install in python: mpl_toolkits.basemap import Basemap need matplotlib 0.98 not 0.91 in python: mpl_toolkits.basemap import Basemap need matplotlib 0.98 not 0.91 2.2 - download updated version http://sourceforge.net/project/showfiles.php?group_id=80706 download basemap: http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792&release_id=653688 double click: matplotlib-0.98.5.2-py2.5-macosx10.5.mpkg 3. that didn't work, installing WHOLE NEW VERSION of Enthought which has matplotlib 0.98 http://www.enthought.com/products/epddownload.php redo install of basemap: http://matplotlib.sourceforge.net/basemap/doc/html/users/installing.html cd /Users/nick/Desktop/downloads/basemap-0.99.3/ cd geos-2.2.3 export GEOS_DIR=/usr/local ./configure --prefix=$GEOS_DIR make sudo make install cd .. python setup.py install in python: mpl_toolkits.basemap import Basemap invalid syntax from mpl_toolkits.basemap import Basemap this works! test: cd examples python simpletest.py python run_all.py basemap: most things worked, but not all.

Hi Mauro & Lionel,
I tried changing the backend to WX (and WxAgg) via the matplotlibrc

Hi Mauro,
Update:
1. I went to the place that threw an error in the basemap code:
>>
"/Library/Frameworks/Python.framework/Versions/4.1.30101/lib/python2.5/site-packages/basemap-0.99.1.0001-py2.5-macosx-10.3-fat.egg/mpl_toolkits/basemap/__init__.py",
>> line 2501, in set_axes_limits
>> figManager.canvas.draw()
>> AttributeError: 'NoneType' object has no attribute 'canvas'
>>
>>
The code is:
============
# force draw if in interactive mode.
if is_interactive():
figManager = _pylab_helpers.Gcf.get_active()
figManager.canvas.draw()
============
So, I changed "interactive = true" to "interactive = false" in my
matplotlibrc file.
Now when I run "python Croizat.py", I get no error messages, and the
graphic of a world map comes up.
I can get rivers etc. to display correctly.
2. However, I tried opening the America.prj project file, and the
various *.csv files in the /samples directory, and couldn't get anything
to display (perhaps because interactive mode is off?).
When I clicked on the the various analysis options (e.g. track
analysis), I get "Number of data files must be >= 1". This probably
means the files aren't actually loading...
2a. Workaround: When I copied the *.prj file and the *.csv files from
Croizat/sample to the main Croizat directory, then I was able to open
things fine, and run the analyses.
So basically it looks like it works now. Recommend you post this where
appropriate for other users.
Cheers!
Nick

Croizat is calling pylab here via basemap, which is a bug. Croizat is a wx app, and should never import pylab or pyplot. This is happening somewhere in basemap, most likely a call to basemap is not passing in an axes or figure instance in. When basemap gets a default axes instance of None, it imports pyplot and creates its own. I have no idea why this is happening on one platform and not another for Croizat, but this is where the bug is occurring most likely. A good way to track this down is to remove matplotlib/pyplot.py from site-packages and rerun. The stack trace should show you which Croizat/basemap call is triggering the import, and you can fix it there. The fix you are trying is dangerous, unsupported, and likely to fail in unpredicatable ways. JDH |

From a cursory look at the code, it looks like the app is not letting basemap create it's own axes instance with pyplot. It's just that if basemap finds that is_interactive is True, it will use pyplot for force the canvas to be drawn. -Jeff ---- Jeffrey S.

Maybe a backend problem, since your soft is based on wx and the user uses Tk : ... > Using fontManager instance from /Users/nick/.matplotlib/fontManager.cache > backend TkAgg version 8.4 > Traceback (most recent call last): > File "Croizat.py", line 71, in <module> > Croizat = Application(0) ... -- Lionel Roubeyrie chargé d'études LIMAIR - La Surveillance de l'Air en Limousin http://www.limair.asso.fr |
