pip3 install -i sklearn 安装报错

报错信息

ERROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.

解决方法：
网络问题，重试几次就好了，加超时时间，修改源

pip install --default-timeout=1000 -i https://pypi.tuna.tsinghua.edu.cn/simple sklearn

sklearn 修改成你需要安装的插件
