import pandas as pd # 假设数据集已经加载到DataFrame df中 print(df.head()) # 查看前几行数据,确认标签列是否存在 print(df['label_column'].value_counts()) # 查看标签的分布,确保标签不为空 如果标签列确实为空或不存在,你需要回溯到数据加载和预处理阶段,找出问题所在。 查找相关的计算指标代码或库...
我认为问题源于先设置重复索引，然后再做groupby。相反，我建议您先按cube分组，然后在每个组内进行插值：
You can simply rename DataFrame column names using DataFrame.rename() . DataFrame.rename({'oldName1': 'newName1', 'oldName2': 'newName2'}, axis=1) Lets create a DataFrame.. import pandas as pd import numpy as np df = pd.DataFrame() df['A'] = [12,13,12] df['B'] = [45...
