## Model Overview
This model is a compiled version of [Watashiha-Llama-2-13B-Ogiri-sft](https://huggingface.co./watashiha/Watashiha-Llama-2-13B-Ogiri-sft) designed to run on AWS's inf2 instances.

The compilation was done following the instructions in this article:
https://huggingface.co./docs/optimum-neuron/tutorials/llama2-13b-chatbot

* License: LLAMA 2 COMMUNITY LICENSE]

## How to Use
1. Launch an **inf2.xlarge** instance on AWS EC2.
   As downloading the model requires about 50GB, it is recommended to set the storage size to 256GB or more.
   Please use the following AMI:
   **Deep Learning AMI Neuron PyTorch 1.13 (Ubuntu 20.04) 20240102**

2. Execute the following command to activate the provided Python environment.
```bash
source /opt/aws_neuron_venv_pytorch/bin/activate
```

3. Install **optimum**.
```bash
pip install optimum[neuronx]
```

4. Once the above steps are completed, execute the provided source code.
```python
from optimum.neuron import NeuronModelForCausalLM
from transformers import AutoTokenizer

model_name = "watashiha/Watashiha-Llama-2-13B-Ogiri-sft-neuron"
tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=True)
model = NeuronModelForCausalLM.from_pretrained(model_name)

odai = "What happens when a clock is hungry?"
text = f"""
