# Llama2 7B for Greek: 100 target vocabulary size + Merge target vocabulary initialization

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

## Model Details

* **Vocabulary**: This model has an additional 100 target vocabulary.
* **Target vocabulary initialization**: The target weights of the embedding and LM head were initialized using Merge initialization.
* **Training**: This model was additionally pre-trained on 30K target language sentences sampled from CC-100.

## Model Description

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

## 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(
    "atsuki-yamaguchi/Llama-2-7b-hf-el-30K-merge"
)
model = PeftModelForCausalLM.from_pretrained(
    model,
    "atsuki-yamaguchi/Llama-2-7b-hf-el-30K-merge"
)
model = model.merge_and_unload()
tokenizer = AutoTokenizer.from_pretrained(
    "atsuki-yamaguchi/Llama-2-7b-hf-el-30K-merge"
)
```
