russian_stt_text_normalization's Issues

Примеры, на которых модель падает

Два предложения из примера через точку и \n работают, через точку и пробел или запятую или пробел - падают:
"С 12.01.1943 г. площадь сельсовета — 1785,5 га. С 12.01.1943 г. площадь сельсовета — 1785,5 га".
А такие два предложения через \n не работают, а через пробел - работают:
"""Для нач+ала работы введите Ваш текст сюда.
Для нач+ала работы введите Ваш текст сюда"""

Окончания чисел

from normalizer import Normalizer
 
text_list = [
    'в 23 кабинете', 
    'разделить на 2 части', 
    'нет 2 части', 
    'я хочу попасть в 156 квартиру'
]
norm = Normalizer()
 
results = [norm.norm_text(text) for text in text_list]
print(results)

Код выше выдает:

[
    'в двадцать три кабинете', 
    'разделить на два части', 
    'нет два части', 
    'я хочу попасть в сто пятьдесят шесть квартиру'
]

Часть примеров взяты из https://habr.com/ru/post/491260 -- возможно не тот pretrained выложен?

RuntimeError в ноутбуке при повторном вызове norm_text

В ноутбке при повторном вызове метода модель падает с RuntimeError.

Не могу запустить

Подскажите в чем может быть проблема, я новичек в python, клонировал этот репозиторий, установил зависимости, создал test.py с примером из README, при запуске получаю ошибку:
Legacy model format is not supported on mobile.
File "C:\Users\Mi\Documents\GitHub\russian_stt_text_normalization\normalizer.py", line 18, in init
self.model = torch.jit.load(jit_model, map_location=device)
File "C:\Users\Mi\Documents\GitHub\russian_stt_text_normalization\test.py", line 5, in
norm = Normalizer()

Installation

Sorry, can you explain how do i install this model?

What the best practises of using this lib for stt?

I have zero experience in making STT models so please, advise me.

I'm using your open_stt (thanks!) with SeanNaren/deepspeech.pytorch for building STT model. So as you know, I must provide labels for training.

What the intuition behind using string.punctuation and uppercase or lowercase at the same time? Should I provide this(below) as labels or left only space and chars (e.g. lowercase)?

# punctuation + space + rus
self.tgt_vocab = {token: i+5 for i, token in enumerate(punctuation + rus_letters + ' ' + '«»—')}

Пример из README выдает другой результат

from normalizer import Normalizer

text = 'С 12.01.1943 г. площадь сельсовета — 1785,5 га.'

norm = Normalizer()
result = norm.norm_text(text)
print(result)

В README:

>>> С двенадцатого января тысяча девятьсот сорок третьего года площадь сельсовета
>>> — тысяча семьсот восемьдесят пять целых и пять десятых гектара

Но выдает:

С двенадцати.один.тысяча девятьсот сорок третий год. площадь сельсовета — тысяча семьсот восемьдесят пять целых и пять десятых гектара.
