Python problems

[zeevgr2]

Using Ubuntu 16.04
Build

1. Updated CMakeLists.txt: set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -std=gnu++0x")
2. From build folder: cmake -D BUILD_PYTHON_SUPPORT=ON .. and make -j4
3. Followed README.md for python: cp -r ../python/* python/

Testing

1. ../run_simple_vehicle_counting.sh runs OK

2. ../run_python_demo.sh
   Traceback (most recent call last):
   File "./build/python/demo.py", line 4, in
   import analysis
   File "/home/zeev/PYTHON/SIMPLE-VEHICLE-COUNT/simple_vehicle_counting/build/python/analysis/init.py", line 6, in
   import pyboostcvconverter as pbcvt
   ImportError: No module named pyboostcvconverter

3. Apparently __init__.py was missing in pyboostconverter folder, so entered
   touch python/pyboostcvconverter/__init__.py

4. ../run_python_demo.sh
   PBAS()
   PixelBasedAdaptiveSegmenter()
   VehicleCouting()
   BlobTracking()
   ../run_python_demo.sh: line 4: 2089 Segmentation fault (core dumped) python ./build/python/demo.py

Any suggestions to help locate the problem?

Exactly the same here, ubuntu 16.04.
(PBAS:32707): Gtk-CRITICAL **: IA__gtk_widget_new: assertion 'g_type_is_a (type, GTK_TYPE_WIDGET)' failed
../run_python_demo.sh: line 3: 32707 Segmentation fault (core dumped) python ./build/python/demo.py

Not sure where this came from, seems like it may be related to matplotlib however I have been using this lib for plotting recently and it works fine.
