我正在尝试一个OpenCV教程，当我运行python代码时出现了这个错误
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 /home/pankaja/Desktop/OpenCV-tmp/opencv/modules/highgui/src/window.cpp, line 611
Traceback (most recent call last):
File "/home/pankaja/PycharmProjects/ImageProcessing/imageprocess.py", line 8, in <module>
cv2.imshow('image', img)
cv2.error: /home/pankaja/Desktop/OpenCV-tmp/opencv/modules/highgui/src/window.cpp:611: error: (-2) 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 function cvShowImage
至于OpenCV error: the function is not implemented这个stackoverflow的答案，我尝试了命令 sudo apt-get install libopencv - * 并得到了这个，

如何解决这个问题？我做错了什么？
