## 我的系统是window系统，用的pycharm，python版本是3.9.4，opencv版本号是4.7.0.68 ■opencv\_ contrib. _python-4.7.0.68.dist-info ■opencv_ contrib\_ python headless-4.7.0.68.dist-info ■opencv\_ python-4.7.0.68.dist-info ■opencv\_ python. headless-4.7.0.68.dist-info 我想知道报这个错的解决办法是啥，问题是在哪里，我有点晕了。

I want to know what is the solution to this error and where is the problem. I’m a little dizzy. 😢

you’ve installed far too many (4 !) opencv versions on the same machine. uninstall them all, then pick _exactly one_  
(probably : ` pip install opencv_contrib_python` )

((also, just saying: the ‘headless’ versions are for e.g. webservers, no gui there !))
