在opencv-python中的imshow不起作用

當我執行cv2.imshow時發生錯誤和程序崩潰。在opencv-python中的imshow不起作用

我的代碼只是

import cv2 
sscv = cv2.imread('/home/myuser/Pictures/Workspace 1_007.png',0) 
cv2.imshow("screenshot image", sscv) 
cv2.waitKey(0)

使用

Ubuntu的14.0.4
的Python 2.7.6

CV2 2.4顯示錯誤是

/home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: cannot register existing type 'GdkDisplayManager' 
     cv2.imshow("screenshot image", sscv) 
    /home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: g_once_init_leave: assertion 'result != 0' failed 
     cv2.imshow("screenshot image", sscv) 
    /home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: g_object_new: assertion 'G_TYPE_IS_OBJECT (object_type)' failed 
     cv2.imshow("screenshot image", sscv) 
    /home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: invalid (NULL) pointer instance

     cv2.imshow("screenshot image", sscv) 
    /home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: cannot register existing type 'GdkDisplay'

     cv2.imshow("screenshot image", sscv) 
    Segmentation fault (core dumped)

那有什麼問題？

FWIW它工作正常使用''在Ubuntu 14.04 3.0.0-dev'' –

我看到一個類似的未解決的錯誤使用ubuntu 14.04在這裏也http://stackoverflow.com/questions/26100516/opencv-code-throws-segmentation-errorcore-dumped-ubuntu-14-04，該代碼也適用於我很好 –

你是如何安裝OpenCV的？ –

嘗試重新安裝這些依賴，並讓我知道如果問題仍然存在

sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg cmake qt5-default checkinstall

之後只是做

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON .. 
make -j2 
sudo checkinstall 
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf' 
sudo ldconfig
