Hi, I am confused about that I can't use some functions in Python. When I call the imshow() in C++, it works without any error. However, when I use python calling imshow, the error occurs as follow:

*Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvShowImage*

However,I have already installed libgtk2.0-dev and pkg-config. So I rebuilt opencv as official tutorials again with some information on the console:

As a result , I met the error again. Now I really have no idea about my errors. Could you please give some advice? Thank you very much. And my python version is about 2.7 and Ubuntu is 14.04 I am looking forward to your reply. Thank you very much! Weiyi

========================================================

Sorry about screenshots.

The cv2.getBuildInformation() as follow:

GUI: 

QT:                          NO
GTK+:                        NO
GThread :                    YES (ver 2.12.3)
GtkGlExt:                    NO
OpenGL support:              NO
VTK support:                 NO

But when I command cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. the information is as follow:

GUI: 

QT:                          NO
GTK+:                        YES(ver 2.24.23)
GThread :                    YES (ver 2.12.3)
GtkGlExt:                    NO
OpenGL support:              NO
VTK support:                 NO

And I also notice that the cv2.getBuildInformation() gives the information :

Python 2:

Interpreter:                 python (ver 2.7.13)
Libraries:                   
numpy:                       /opt/python/cp27-cp27mu/lib/python2.7/site-packages/numpy/core/include (ver 1.11.1)
packages path:               /opt/python/cp27-cp27mu/lib/python2.7/site-packages

but I didn't find any python under opt folder and command cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. the information is as follow:

Python 2:

Interpreter:                 python (ver 2.7.6)
Libraries:                   /usr/lib/x86_64-linux-gnu/libpython2.7.so (ver 2.7.6)
numpy:                       /usr/local/lib/python2.7/dist-packages/numpy/core/include (ver 1.13.3)
packages path:           lib/python2.7/site-packages

maybe you're not using your newly built cv2.so, but some older version.

check cv2.__version__ and cv2.getBuildInformation() , and see, if that matches your expectations.

possible reasons:

  • forgot to run make install
  • virtual envs with stale copies
  • installing to one python, but using another

thanks for the edit !

so, you have 2 python versions, and the new cv2 got installed to the 2.7.6 one in /usr/local

but the old version python2.7.13 doesn't exit in the path /opt/python/cp27-cp27mu/lib/python2.7/site-packages. my opt folder doesn't have any python
