【环境踩坑】用opencv打开图片时报错

用opencv打开图片时报错：

linux OpenCV(4.4.0) /tmp/pip-build-z1z9fpzr/opencv-python/opencv/modules/highgui/

 If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

解决方法：

pip3 install opencv-contrib-python
 

建议设置pip源到阿里云～～～安装包简直不要太顺利
