python在调用负责为我的Naive bayes分类器生成特性的函数时返回none

我编写了一个python脚本，用于从文本行中提取功能： 我试图用标记B和i执行句子分割任务，其中B代表开始，i~代表内部。因此，我训练了朴素贝叶斯分类器。其中data_object其中data object是一个列表，如下所示：-

[["Awards & Recognition"]
 ["Awards", "&" ,"Recognitions"]
 ["Award", "&", "Recognition"]
 ["NNP", "CC", "NNS"]
 ["B"]]

而cue1、cue2、cue3、cue4、cue5、cue6、cue7、cue8和tab是单词列表

那么您的问题是？。刚才编辑您的问题提到了

无

，但您显示的功能函数无法返回该值。你的问题是什么？你的功能转储没有告诉我你想知道什么。负责训练集训练集的函数是：-def feature_set（data_objects）：feature_set=[]feature_set=[（feature_提取器（data_object），data_object[4]），用于data_objects中的data_object]返回feature_set feat=feature_set（build_data_objects（））训练集，test_set=feat[：1200]，feat[1200:1800]除此之外，没有其他函数可以对none值负责，因此您的问题是？。刚刚编辑您的问题提到
