迭代存储SelectKBest algori选择的功能的数组时出现Keyerror 1问题

Question

我犯了这个错误

pandas/_libs/index.pyx in pandas._libs.index.IndexEngine.get_loc()

pandas/_libs/index.pyx in pandas._libs.index.IndexEngine.get_loc()

pandas/_libs/index.pyx in pandas._libs.index.IndexEngine._get_loc_duplicates()

KeyError: 1

循环时抛出一个数组

kbest_feature_corre

i = 0
while i < len(kbest_feature_corre):
    print(kbest_feature_corre[i])
    i += 1

数组看起来像这样

我想打印数组的所有结果，但在这里找不到出错的地方：/ 数组存储应用SelectKBest算法进行特征选择的结果
