Genz Tokenize

Using for tokenize

    from genz_tokenize import Tokenize
    # using vocab from lib
    tokenize = Tokenize()
    print(tokenize('sinh_viên công_nghệ', 'hello', max_len = 10, padding = True, truncation = True))
    # {'input_ids': [1, 770, 1444, 2, 2, 30469, 2, 0, 0, 0], 'attention_mask': [1, 1, 1, 1, 1, 1, 1, 0, 0, 0], 'sequence_id': [None, 0, 0, None, None, 1, None]}

    print(tokenize.decode([1, 770, 2]))
    # <s> sinh_viên </s>

    # from your vocab
    tokenize = Tokenize.fromFile('vocab.txt','bpe.codes')
