python安装xgboost报错

ERROR: Could not find a version that satisfies the requirement xgboost (from versions: none)
ERROR: No matching distribution found for xgboost

解决办法：

换成国内的pip源

pip install xgboost -i http://pypi.doubanio.com/simple/ --trusted-host py

看提示还是报错：

换为阿里云就可以了

pip install xgboost -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
