置换特征重要性的代码实现[12]+实验结果:我用的jupyter notebook,底下代码里的每一小段就是jupyter里的一个小模块。 # machine learning model import xgboost as xgb model = xgb.XGBRegressor(n_estimators=500, max_depth=20, learning_rate=0.1, subsample=0.8, random_state=33) model.fit(df_features, d...
importxgboost xgboost.__version__ Out: "0.81" 方法二:Conda安装 首先从terminal里面直接输入conda安装命令也是行不通的 conda install xgboost PackagesNotFoundError: The following packages are not available from current channels: - xgboost 根据这篇文章,可以用下面的指令搜索,然后根据自己的系统版本及python环...
