此问题之前已被问过，但它的答案并不适用于我。
$ python video.py
输出：
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 cvNamedWindow, file

路径"/home/aunmesh/project-infinity/sirius-application/opencv-2.4.9/modules/highgui/src/window.cpp:483"不再存在，因为我删除了它，并在另一个目录中重新安装了opencv 3.0.0：
/home/aunmesh/opencv-master/。
也许某些路径变量或配置设置有误。请告诉我如何解决这个问题（我认为python正在查看文件夹的错误位置）
