时间转换错误

[dospeech]

文本输入是“下午三点三十分”会被转为3:30.pm. 当想输出为“下午3:30分”时修改如下： time.tsv里面pm改为下午，同时将time.py的 verbalizer = (hour + addcolon + minute + (addcolon + second).ques + noon.ques) 改为 verbalizer = (noon.ques + hour + addcolon + minute + insert('分') + (addcolon + second).ques)

结果报错如下： File "/mnt/weTextProcessing/tn/processor.py", line 96, in normalize return self.verbalize(self.tag(input)) File "/mnt/weTextProcessing/tn/processor.py", line 93, in verbalize return shortestpath(lattice, nshortest=1, unique=True).string() File "extensions/_pynini.pyx", line 462, in _pynini.Fst.string File "extensions/_pynini.pyx", line 507, in _pynini.Fst.string _pywrapfst.FstOpError: Operation failed 请问大佬，该怎么改，是不是我哪里改的不对？
