So silly. You're right. I'll delete the PYTHONPATH setting from the profile file. So, I guess the only way is to recompile QGIS to use the newer version of Python (with Scipy 0.12) or compile Scipy 0.12 to be used with system Python. If you're working on it, that will be great (it's necessary for QGIS Animove plugin support on Mac, one project I've been working on) Best regards, -- Jorge Arévalo http://geomati.co ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

One possibility then is that your ~/.bash_profile has a PYTHONPATH setting, maybe from installing Python 2.7, to add the Library/Frameworks/Python.framework/... site-packages to your sys.path. This would let the system python see modules installed in the python.org python folder, but QGIS won't see these because OS X applications don't get the shell environment. Using PYTHONPATH to add python.org stuff to the system python is a bit dangersous because binary components of modules (ie scipy has binary code) are built for a specific version of Python (but not necessarily same installation in this case). Loading scipy for python.org 2.7, in system python 2.6 may seem to load fine but have problems when you try to use scipy functionality, but a scipy for python.org 2.6 should work in the system python 2.6. - William Kyngesburye http://www.kyngchaos.com/ "Oh, look, I seem to have fallen down a deep, dark hole.

I tried downloading the sources and compiling them with system python (/usr/bin/python2.6 setup.py build), but I got a bunch of errors. I guess that's what you're dealing with. I also installed Python 2,7 from Python.org, but I didn't install Python 2.6. The difference I saw is that sys.path is not the same from command line (Python 2.6) than from QGIS console. From QGIS console, sys.path doesn't include the Scipy 0.12 location. From command line, does. > Same version of Python does not necessarily mean same installation of Python, > on OS X.

Yes. python and python2.7 are the same: /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7, and /usr/local/bin/python is also a symlink to the previous one. But python2.6 is /usr/bin/python2.6 (system Python). I feel confused for this reason: - Executing python2.6 from command line (system Python, not installed by me): scipy 0.12 is detected - Executing python from QGIS console (I assume is also system Python, as you said): scipy 0.11 is detected Difference is in sys.path.

Re: [Qgis-developer] Force QGIS to use a different version of Python in Snow Leopard
Where did you get this Scipy? If it's from Scipy, then it is NOT for the system Python, and you probably installed Python 2.6 (as well as 2.7) from Python.org. I don't know of anyone else building a Scipy for the system python, or I wouldn't bother myself. Same version of Python does not necessarily mean same installation of Python, on OS X. From the Terminal you can find out what Python is found: type python type python2.6 type python2.7 System pythons will be in /usr/bin. python.org python will probably be in /usr/local/bin, or /Library/Frameworks.

Re: [Qgis-developer] Force QGIS to use a different version of Python in Snow Leopard
Many thanks for your response, William. It's curious, because I've installed scipy 0.12 for system Python from command line, but QGIS can't detect it. So, if I execute this from command line: python2.6 >>> import scipy >>> scipy.version.version I see 0.12 as version number. But from QGIS plugins --> Python console, if I execute >>> import scipy >>> scipy.version.version I see 0.11.0 Even when I'm using the same Python version (exactly the same), the Python path is different in console than in QGIS. And I don't know why.

Re: [Qgis-developer] Force QGIS to use a different version of Python in Snow Leopard
You can't. QGIS includes its own python interpreter and links directly to the Python framework. This ties it to a specific version and distribution (ie system Python 2.6). You either need to compile your own QGIS to use the other python, or install scipy for the system python. I'm working on updating my Scipy distribution if you can wait, I just got distracted by the fortran requirement.
