试了一晚上各种方法都不行
1、在pycharm里搜索“xgboost”从hithub上导入，下了四五个小时还是installing
2、在cmd install 显示以下错误：
C:\Users\HP>pip install xgboost
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting xgboost

搞了一晚上了，月底要交论文，求指点！
首先，请在teiminal执行pip，不要使用cmd，会把环境弄乱。
当然，你现在的问题是下载没有ssl证书，超时。
所以解决方法：
pip install xgboost -i https://pypi.tuna.tsinghua.edu.cn/simple
