# Vietnamese Fine-tuned Llama-2-7b-chat-hf

This repository contains a Vietnamese-tuned version of the `Llama-2-7b-chat-hf` model, which has been fine-tuned on Vietnamese datasets using LoRA (Low-Rank Adaptation) techniques.



## Model Details

This model is a fine-tuned version of the Llama-2-7b-chat-hf model, specifically adapted for improved performance on Vietnamese language tasks. It uses LoRA fine-tuning to efficiently adapt the large language model to Vietnamese data while maintaining much of the original model's general knowledge and capabilities.

### Model Description

<!-- Provide a longer summary of what this model is. -->



- **Developed by:** [Daniel Du](https://github.com/danghoangnhan)
- **Model type:** Large Language Model
- **Language(s) (NLP):** Vietnamese
- **License:** [More Information Needed]
- **Finetuned from model [optional]:** [meta-llama/Llama-2-7b-chat-hf](https://huggingface.co/meta-llama/Llama-2-7b-chat-hf)
- **Language:** Vietnamese


### Direct Use

You can use this model directly with the Hugging Face Transformers library:

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel, PeftConfig

# Load the base model
base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-7b-chat-hf")

# Load the LoRA configuration and model
peft_model_id = "CallMeMrFern/Llama-2-7b-chat-hf_vn"
config = PeftConfig.from_pretrained(peft_model_id)
model = PeftModel.from_pretrained(base_model, peft_model_id)

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-2-7b-chat-hf")

# Example usage
input_text = "Xin chào, hôm nay thời tiết thế nào?"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs, max_length=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```


### Downstream Use [optional]

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->

[More Information Needed]

### Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

## Bias, Risks, and Limitations

- This model is specifically fine-tuned for Vietnamese and may not perform as well on other languages.
- The model inherits limitations from the base Llama-2-7b-chat-hf model.
- Performance may vary depending on the specific task and domain.

### Recommendations

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

## Model Description

This model is a fine-tuned version of the Llama-2-7b-chat-hf model, specifically adapted for improved performance on Vietnamese language tasks. It uses LoRA fine-tuning to efficiently adapt the large language model to Vietnamese data while maintaining much of the original model's general knowledge and capabilities.

## Fine-tuning Details

- **Fine-tuning Method:** LoRA (Low-Rank Adaptation)
- **LoRA Config:** 
  - Target Modules: `["q_proj", "v_proj"]`
  - Precision: 8-bit
- **Dataset:** `alpaca_translate_GPT_35_10_20k.json` (Vietnamese translation of the Alpaca dataset)

## Training Procedure

The model was fine-tuned using the following command:

```bash
python finetune/lora.py \
--base_model meta-llama/Llama-2-7b-chat-hf \
--model_type llama \
--data_dir data/general/alpaca_translate_GPT_35_10_20k.json \
--output_dir finetuned/meta-llama/Llama-2-7b-chat-hf \
--lora_target_modules '["q_proj", "v_proj"]' \
--micro_batch_size 1
```

For multi-GPU training, a distributed training approach was used.
