Ubuntu 16.04运行Python OpenCV显示图片时报错，内容如下：
cv2.imshow(‘window’,image)
cv2.error: OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474/work/modules/highgui/src/window.cpp:632: error: (-2: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 function ‘cvShowImage’
可能是因为新版本不兼容问题，解决办法为在终端输入：
conda remove opencv
conda install -c menpo opencv
pip install --upgrade pip
pip install opencv-contrib-python (关键）
