要进行数据集训练时需要下载opencv-python, pycocotools，但是出现了错误，如下

Collecting package metadata (current_repodata.json): .working.done
Solving environment: ...working... failed with initial frozen solve. Retrying with flexible solve.

有人知道怎么办吗
安装了ancconda pycharm

不妨试一试先换个源，清华源之类的再安装一遍试试

pip --default-timeout=100 install 库名称 -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

pip install opencv-python == 4.1.2
