我正在尝试通过
访问数据框dtSortedTable的一行dtSortedTable.loc[decisionCountSorted.index[0]]
dtSortedTable是
X0 X1 X2
(D1, G2) A B C
(D2, G1) A A A
(D2, G0) A A C
decisionCountSorted索引如下：
Index([('D1', 'G2'), ('D2', 'G1'), ('D2', 'G0')], dtype='object')
decisionCountSorted的索引与dtSortedTable完全相同。索引分为2级。为什么会出现以下错误？我需要对DecisionCountSorted运行一些测试，并从dtSortedTable中提取相应的行。任何帮助将不胜感激！
