Indobenchmark Toolkit

Indobenchmark are collections of Natural Language Understanding (IndoNLU) and Natural Language Generation (IndoNLG) resources for Bahasa Indonesia such as Institut Teknologi Bandung, Universitas Multimedia Nusantara, The Hong Kong University of Science and Technology, Universitas Indonesia, DeepMind, Gojek, and Prosa.AI.

Toolkit Modules

IndoNLGTokenizer

IndoNLGTokenizer is the tokenizer used by both IndoBART and IndoGPT models. The example for using the IndoNLGTokenizer is shown as follow:

• IndoNLGTokenizer for IndoGPT

## Encode ##
from indobenchmark import IndoNLGTokenizer
tokenizer = IndoNLGTokenizer.from_pretrained('indobenchmark/indogpt')
inputs = tokenizer.prepare_input_for_generation('hai, bagaimana kabar', model_type='indogpt', return_tensors='pt')
# inputs: {'input_ids': tensor([[    0,  4693, 39956,  1119,  3447]]), 'attention_mask': tensor([[1, 1, 1, 1, 1]])}

## Decode ##
from indobenchmark import IndoNLGTokenizer
tokenizer = IndoNLGTokenizer.from_pretrained('indobenchmark/indogpt')
text = tokenizer.decode([0,  4693, 39956,  1119,  3447])
# text: '<s> hai, bagaimana kabar'

• IndoNLGTokenizer for IndoBART

## Encode ##
from indobenchmark import IndoNLGTokenizer
tokenizer = IndoNLGTokenizer.from_pretrained('indobenchmark/indobart')
inputs = tokenizer.prepare_input_for_generation('hai, bagaimana kabar', return_tensors='pt', 
                       lang_token = '[indonesian]', decoder_lang_token='[indonesian]')
# inputs: {'input_ids': tensor([    0,  4693, 39956,  1119,  3447,     2, 40002]), 'attention_mask': tensor([1, 1, 1, 1, 1, 1, 1])}

## Decode ##
from indobenchmark import IndoNLGTokenizer
tokenizer = IndoNLGTokenizer.from_pretrained('indobenchmark/indobart')
text = tokenizer.decode([0,  4693, 39956,  1119,  3447, 2, 40002])
# text: '<s> hai, bagaimana kabar </s> [indonesian]'

note: IndoNLGTokenizer will automatically lower case the text input since both the IndoNLGTokenizer, the IndoBart, and the IndoGPT models are only trained on lower-cased texts.
