调用 XGBoost 时遇到如下 FutureWarning：

compat.py:36: FutureWarning: pandas.Int64Index is deprecated and will be removed from pandas in a future version. Use pandas.Index with the appropriate dtype instead.
  from pandas import MultiIndex, Int64Index


data.py:267: FutureWarning: pandas.Int64Index is deprecated and will be removed from pandas in a future version. Use pandas.Index with the appropriate dtype instead.
  elif isinstance(data.columns, (pd.Int64Index, pd.RangeIndex)):

我的解决方法：

pip uninstall pandas
pip install pandas==1.3

其他解决方案说降低 xgboost 的版本，或者先导入 MultiIndex, Int16Dtype，如下所示：

import pandas as pd 
from pandas import MultiIndex, Int16Dtype
import xgboost as xgb
