Solving environment: failed with initial frozen solve. Retrying with flexible solve
使用conda安装时经常遇到以下问题：
$ conda install -c conda-forge opencv=4.2.0
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: / failed with repodata from current_repodata.json, will retry with next repodata source.
