Mistake when changing the example a little

g2p("我写了一行代码")
Out[4]:
[('我', 'r', 'wo3', 'wo2', '/I/me/my/', '我'),
('写', 'v', 'xie3', 'xie3', '/to write/', '寫'),
('了',
'u',
'le5',
'le5',
'/(modal particle intensifying preceding clause)/(completed action marker)/',
'了'),
('一行', 'n', 'yi1 xing2', 'yi4 xing2', '/party/delegation/', '一行'),
('代码', 'n', 'dai4 ma3', 'dai4 ma3', '/code/', '代碼')]

The program (word segmentation) thinks that '一行' is a word as transcribed (which is not what we expect), instead of being a phrase pronouncing "yi4 hang2" and meaning "a line of" (which is correct).
