# Llama2 7B for Greek: 100 target vocabulary size + Align target vocabulary initialization + 2 Stage training
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 Align initialization.
* **Training**: This model was additionally pre-trained on 30K target language sentences sampled from CC-100. The training was conducted with the 2 Stage strategies introduced in the paper.
## Model Description
- **Language:** Greek
- **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(
"atsuki-yamaguchi/Llama-2-7b-hf-el-30K-align-2stage"
)
model = PeftModelForCausalLM.from_pretrained(
model,
"atsuki-yamaguchi/Llama-2-7b-hf-el-30K-align-2stage"
)
model = model.merge_and_unload()
tokenizer = AutoTokenizer.from_pretrained(
"atsuki-yamaguchi/Llama-2-7b-hf-el-30K-align-2stage"
)
```
