I using python opencv3.2 in ubuntu14.04,install follow open-python 3.2.0.7 : Python Package Index, and installed by pip but still get error when call cv2.imshow()

OpenCV Error: Unspecified error (The function is not implemented. 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 cvShowImage, file /io/opencv/modules/highgui/src/window.cpp, line 583

, so I try build opencv 3.2.0 followed Install OpenCV 3.0 and Python 2.7+ on Ubuntu,but i didn't see the cv2.so after make install

CMake: cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..

where i can find cv2.so ?

Sounds like CMake never found your Python dev libararies and/or numpy libraries.
Be sure to sudo apt install libpython2.7-dev and sudo pip install numpy then specify to CMake where these libraries are using the flags: -D PYTHON2_INCLUDE_DIR=/usr/include/python2.7 \ -D PYTHON2_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython2.7.so \ -D PYTHON2_NUMPY_INCLUDE_DIRS=/usr/lib/python2.7/dist-packages/numpy/core/include \ -D PYTHON2_PACKAGES_PATH=/usr/lib/python2.7/dist-packages
The above is for python 2.7 only.

then build and install:
make -j$(nproc) sudo make -j$(nproc) install

The cv2.so file should now reside in your python site-packages or dist-packages folder.
