我执行cv2.imshow时发生错误，程序崩溃。
我的代码只是
import cv2 sscv = cv2.imread('/home/myuser/Pictures/Workspace 1_007.png',0) cv2.imshow("screenshot image", sscv) cv2.waitKey(0)
显示错误是
/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: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed 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) /home/mallory/workspace/python-autoaction/test/test_xutils.py:11: Warning: g_type_register_static: assertion 'parent_type > 0' failed cv2.imshow("screenshot image", sscv) Segmentation fault (core dumped)
运用
那有什么问题？
尝试再次安装这些依赖关系，让我知道如果问题仍然存在
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
之后，就这样做
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
