Documentation/Labs/SlicerCondaIntegration

Slicer currently builds a custom python distribution from source, but not all useful packages are available. But Anaconda provides a set of binaries that might provide a more comprehensive ecosystem.

Before attempting to use the whole Anaconda package, the first approach has been to use Miniconda, which is a reduced version of Anaconda.

1: compile Slicer against miniconda

ccmake -DCMAKE_BUILD_TYPE:STRING=Debug -DQT_QMAKE_EXECUTABLE:FILEPATH=/usr/bin/qmake -DPYTHON_EXECUTABLE:FILEPATH=/Users/Jorge/miniconda/bin/python -DPYTHON_INCLUDE_DIR:PATH=/Users/Jorge/miniconda/include/python2.7 -DPYTHON_LIBRARY:FILEPATH=/Users/Jorge/miniconda/lib/libpython2.7.dylib -DCMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.9 -DCMAKE_OSX_SYSROOT:FILEPATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -G "Eclipse CDT4 - Unix Makefiles" ../Slicer-Conda

Doing this, it seems that the Slicer superbuild works ok, and some packages are installed in /Users/Jorge/miniconda/lib/python2.7/site-packages. Ex: gitdb, numpy, SimpleITK-0.9.0.dev656-py2.7-macosx-10.5-x86_64.egg

SimpleITK is not properly installed, when I run miniconda interpreter and try to import it, I get an error:

However, other libraries like gitdb or numpy seem to work properly.
