# Model Card for Taigi-Llama-2-Translator-7B
|
||
The Taigi-Llama-2-Translator series are built based on the Taigi-Llama-2 series model. We conducted fine-tuning on 263k parallel data to create a translation model for Taiwanese Hokkien and related languages.
|
||
|
||
For more details, please refer to our [GitHub repository](https://github.com/lbh0830/TW-Hokkien-LLM/tree/main) and the paper: [Enhancing Taiwanese Hokkien Dual Translation by Exploring and Standardizing of Four Writing Systems](https://arxiv.org/abs/2403.12024)

|
||
## Model description
|
||
|
||
- **Base Model:** [Bohanlu/Taigi-Llama-2-7B](https://huggingface.co/Bohanlu/Taigi-Llama-2-7B)
|
||
- **Usage:** This model can be used for translating between Traditional Chinese or English and Taiwanese Hokkien (Hanzi, POJ, or Hanlo). It also supports translation between different scripts of Taiwanese Hokkien (Hanzi, POJ, Hanlo).
|
||
- **Language(s) (NLP):** Taiwanese Hokkien (Hanzi, POJ and Hanlo), Traditional Chinese and English
|
||
- **Input:** Text in source language
|
||
- **Output:** Text in target language
|
||
- **Model Size:** 7B parameters
|
||
|
||
## Prompt Template
|
||
```
|
||
{BOS}[TRANS]\n{source_sentence}\n[/TRANS]\n[{target_language}]\n
|
||
```
|
||
|
||
- `source_sentence`: The sentence you want to translate.
|
||
- `target_language`: The target language you want to translate to. Use "ZH" for Traditional Chinese, "EN" for English, "POJ" for Taiwanese Hokkien POJ, "HL" for Taiwanese Hokkien Hanlo, and "HAN" for Taiwanese Hokkien Hanzi.
|
||
- Ensure there's a newline at the end.
|
||
|
||
## Usage Example
|
||
```python
|
||
from transformers import AutoModelForCausalLM, AutoTokenizer, TextGenerationPipeline
|
||
import torch
|
||
import accelerate
|
||
|
||
def get_pipeline(path:str, tokenizer:AutoTokenizer, accelerator:accelerate.Accelerator) -> TextGenerationPipeline:
|
||
model = AutoModelForCausalLM.from_pretrained(
|
||
path, torch_dtype=torch.float16, device_map='auto', trust_remote_code=True)
|
||
|
||
terminators = [tokenizer.eos_token_id, tokenizer.pad_token_id]
|
||
|
||
pipeline = TextGenerationPipeline(model = model, tokenizer = tokenizer, num_workers=accelerator.state.num_processes*4, pad_token_id=tokenizer.pad_token_id, eos_token_id=terminators)
|
||
|
||
return pipeline
|
||
|
||
model_dir = "Bohanlu/Taigi-Llama-2-Translator-7B" # or "Bohanlu/Taigi-Llama-2-Translator-13B" for the 13B model
|
||
tokenizer = AutoTokenizer.from_pretrained(model_dir, use_fast=False)
|
||
|
||
accelerator = accelerate.Accelerator()
|
||
pipe = get_pipeline(model_dir, tokenizer, accelerator)
|
||
|
||
PROMPT_TEMPLATE = "[TRANS]\n{source_sentence}\n[/TRANS]\n[{target_language}]\n"
|
||
|
||
def translate(source_sentence:str, target_language:str) -> str:
|
||
prompt = PROMPT_TEMPLATE.format(source_sentence=source_sentence, target_language=target_language)
|
||
out = pipe(prompt, return_full_text=False, repetition_penalty=1.1, do_sample=False)[0]['generated_text']
|
||
return out[:out.find("[/")].strip()
|
||
|
||
source_sentence = "How are you today？"
|
||
|
||
print("To Hanzi: " + translate(source_sentence, "HAN"))
|
||
# Output: To Hanzi: 你今仔日好無？
|
||
|
||
print("To POJ: " + translate(source_sentence, "POJ"))
|
||
# Output: To POJ: Lí kin-á-ji̍t án-chóaⁿ?
|
||
|
||
print("To Traditional Chinese: " + translate(source_sentence, "ZH"))
|
||
# Output: To Traditional Chinese: 你今天好嗎？
|
||
|
||
print("To Hanlo: " + translate(source_sentence, "HL"))
|
||
# Output: To Hanlo: 你今仔日好無？
|
||
