Anaconda 中 opencv的cv2.imshow报错

    cv2.imshow('im',frame)
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'

(opencv版本为3.4.2)

conda remove opencv
conda install -c menpo opencv
pip install --upgrade pip
pip install opencv-contrib-python (关键)

解决

 

或 尝试降低opencv版本 用pip install 安装3.4.1
