在Ubuntu上安装Python的Opencv

Question

Recently I have been trying to install OpenCV on my computer. First I started out by trying to install on Windows. I tried a number of tutorials and kept at it for a while until I gave up. A few people on the forums said that they did the same process I had done on Windows in Ubuntu Linux. Now, I have installed Ubuntu and followed this tutorial. Everything in the tutorial worked well until I ran the find_game.py script and got this error message:

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 Traceback (most recent call last): File "find_game.py", line 24, in cv2.imshow("Image", image) cv2.error: /io/opencv/modules/highgui/src/window.cpp:583: 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.

I have searched every forum and at every one I get some variation of the answer "reload OpenCV with cmake". I have tried to reload OpenCV many times with cmake but every time the same error message pops up. I might have not installed the opencv_contrib libraries correctly, but I know I did follow every step from the tutorial. If anyone has any idea of what I should do it would be a big help.

I resolved my issue. I found out that I had only installed opencv to work with python 2.7 and every time I would only type in python find_game.py . I figured out that when I did this it used the latest version(ie python 3.5) instead of python 2.7 so it wasn't compatible. I easily fixed this by instead doing python2.7 find_game.py .
