+ If you use Mac OS X and got "ImportError: No module named cv2" despite the
fact that
+ you've installed opencv +python27 via MacPorts, you may want to set your
+ PYTHONPATH environment variable to fix this problem:
+
+ # look for the place where cv2 module installed via MacPorts
+ $ sudo port contents opencv|grep py
+ $ export
PYTHONPATH=$PYTHONPATH:/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
+
+ If you use Mac OS X and got "segmentation fault" while running above,
+ your python that was already installed with shipment couldn't suite the
version
+ of the opencv+python27 you've installed via MacPorts. To use MacPorts's
version
+ of python27, check the directory python27 installed and set your PATH
environment
+ variable:
+
+ $ which python
+ # look for the place where python27 command installed via MacPorts
+ $ sudo port contents python27|grep bin
+ $ export
PATH=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin:$PATH
+ # rerun the above
+ $ python run_desc_extractor.py
