# Llama-2
This version was tested with [rocm 5.7](https://github.com/ROCmSoftwarePlatform/AMDMIGraphX/tree/rocm-5.7.0) revision.
## Jupyter notebook
There is a dedicated step-by-step notebook. See [llama2.ipynb](./llama2.ipynb)
## Console application
To run the console application, follow these steps below.
Setup python environment
```bash
# this will require the python venv to installed (e.g. apt install python3.8-venv)
python3 -m venv ll2_venv
. ll2_venv/bin/activate
```
```bash
pip install -r requirements.txt
```
Use MIGraphX Python Module
```bash
export PYTHONPATH=/opt/rocm/lib:$PYTHONPATH
```
Llama2 requires logging to access the models
```bash
huggingface-cli login
```
Get models with optimum
```bash
optimum-cli export onnx --model meta-llama/Llama-2-7b-chat-hf models/llama-2-7b-chat-hf --task text-generation --framework pt --library transformers --no-post-process
```
*Note: `models/llama-2-7b-chat-hf` will be used in the scripts.*
Run the text-generation script with the following example prompt:
```bash
python txtgen.py --prompt "Where is Szeged?" --log-process
```
*Note: The first run will compile the models and cache them to make subsequent runs faster.*
## Gradio application
Note: requires `Console application` to work
Install gradio dependencies
```bash
pip install -r gradio_requirements.txt
```
Usage
```bash
python gradio_app.py
```
This will load the models (which can take several minutes), and when the setup is ready, starts a server on `http://127.0.0.1:7860`.
