起因

因为新建了conda虚拟环境，想在虚拟环境里安装opencv

conda install opencv-python

结果报错：

Collecting package metadata (current_repodata.json): doneSolving environment: failed with initial frozen solve. Retrying with flexible solve.Collecting package metadata (repodata.json): doneSolving environment: failed with initial frozen solve. Retrying with flexible solve.PackagesNotFoundError: The following packages are not available from current channels:- opencv-pythonCurrent channels:

查了很多资料都没解决，最后使用

pip install opencv-python

解决了，？？？？？

总结：conda install 有时候不行，就换pip install。

原因：不知道？？？？？
