Using Accentor.py while reading a file

[dborysowski]

I'm trying to use only Accentor.py (to get only accents, but not transcriptions). I've created a simple code that is reading a file line by line (single word in each line), putting on stress for each word read, adding words to a list and then writing them to an output file. After a 1000 of words I'm getting this error message:

Traceback (most recent call last):
File "/home/user_name/__nsu-ai/russian_g2p/Accentor.py", line 293, in do_accents
res = self.__do_accents(prepared_phrase, morphotags_of_phrase)
File "/home/user_name/__nsu-ai/russian_g2p/Accentor.py", line 524, in __do_accents
cur_accented_wordforms = sorted(self.get_correct_omograph_wiki(root_text, cur_word, morphotags_list[0]))
TypeError: 'NoneType' object is not subscriptable

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "accentize_russian_g2p.py", line 10, in
accented_word = accent.do_accents([[word.strip()]])
File "/home/user_name/__nsu-ai/russian_g2p/Accentor.py", line 308, in do_accents
raise ValueError(err_msg)
ValueError: 'NoneType' object is not subscriptable

I thought it's connected to a specific word, so I deleted it and tried again, but it always stops after 1000 stresses done at 1001st stress to put. Is there any limit set up for Accentor?
