| # T5-EN-VI-SMALL:Pretraining Text-To-Text Transfer Transformer for English Vietnamese Translation | |
| # Dataset | |
| The *IWSLT'15 English-Vietnamese* data is used from [Stanford NLP group](https://nlp.stanford.edu/projects/nmt/). | |
| For all experiments the corpus was split into training, development and test set: | |

| #### Example Using | |
| ``` bash | |
| import torch | |
| from transformers import T5ForConditionalGeneration, T5Tokenizer | |
| import torch | |
| if torch.cuda.is_available(): | |
| device = torch.device("cuda") | |
| print('There are %d GPU(s) available.' % torch.cuda.device_count()) | |
| print('We will use the GPU:', torch.cuda.get_device_name(0)) | |
| else: | |
| print('No GPU available, using the CPU instead.') | |
| device = torch.device("cpu") | |
| model = T5ForConditionalGeneration.from_pretrained("NlpHUST/t5-en-vi-small") | |
| tokenizer = T5Tokenizer.from_pretrained("NlpHUST/t5-en-vi-small") | |
| model.to(device) | |
| src = "In school , we spent a lot of time studying the history of Kim Il-Sung , but we never learned much about the outside world , except that America , South Korea , Japan are the enemies ." | |
| tokenized_text = tokenizer.encode(src, return_tensors="pt").to(device) | |
| model.eval() | |
| summary_ids = model.generate( | |
| tokenized_text, | |
| max_length=128, | |
| num_beams=5, | |
| repetition_penalty=2.5, | |
| length_penalty=1.0, | |
| early_stopping=True | |
| ) | |
| output = tokenizer.decode(summary_ids[0], skip_special_tokens=True) | |
| print(output) | |
| ``` | |
| #### Output | |
| ``` bash | |
| Ở trường, chúng tôi dành nhiều thời gian để nghiên cứu về lịch sử Kim Il-Sung, nhưng chúng tôi chưa bao giờ học được nhiều về thế giới bên ngoài, ngoại trừ Mỹ, Hàn Quốc, Nhật Bản là kẻ thù. | |
