# Llama2 7B for Sinhala: No vocabulary adaptation

This model is built on top of Llama2 7B adapted for Sinhala using 30K target language sentences sampled from CC-100.

## Model Details

* **Vocabulary**: This model has no additional target vocabulary. It retains the original vocabulary of Llama2 7B.


## Model Description

- **Language:** Sinhala
- **License:** Llama 2 Community License Agreement
- **Fine-tuned from model:** meta-llama/Llama-2-7b-hf


## Model Sources

- **Repository:** https://github.com/gucci-j/lowres-cve
- **Paper:** https://arxiv.org/abs/2406.11477

## How to Get Started with the Model
Use the code below to get started with the model.
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModelForCausalLM

model = AutoModelForCausalLM.from_pretrained(
    "meta-llama/Llama-2-7b-hf"
)
model = PeftModelForCausalLM.from_pretrained(
    model,
    "atsuki-yamaguchi/Llama-2-7b-hf-si-30K-lapt"
)
model = model.merge_and_unload()
tokenizer = AutoTokenizer.from_pretrained(
    "meta-llama/Llama-2-7b-hf"
)
```
