解决问题：If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then...‘cvShowImage‘

前几天在做视频目标检测时还是好好的，不知道是不是后面添加了环境还是什么原因，今天检测就出现了下面的错误：

Traceback (most recent call last):
  File "predict.py", line 107, in 
    cv2.imshow("video",frame)
cv2.error: OpenCV(4.6.0) /io/opencv/modules/highgui/src/window.cpp:1267: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa 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'

 应该是opencv出了问题

解决方法：

我之前是用pip install opencv-python安装的，所以得先卸载

pip uninstall opencv-python

然后安装

pip install opencv-contrib-python

 然后运行问题就解决了！
