```console
git clone [email protected]:paion-data/lamassu.git
```

### Running Locally

Create virtual environment and install dependencies:

```console
cd lamassu/mlflow
python3 -m venv .venv
. .venv/bin/activate
pip3 install -r requirements.txt
```

Generate Model with

```console
python3 HanLPner.py
```

A model directory called "HanLPner" appears under `mlflow/models`. Then build Docker image

```console
mlflow models build-docker --name "entity-extraction"
```

and run container with

```console
cp parser.py models/HanLPner/
export ML_MODEL_PATH=/absolute/path/to/models/HanLPner

docker run --rm \
  --memory=4000m \
  -p 8080:8080 \
  -v $ML_MODEL_PATH:/opt/ml/model \
  -e PYTHONPATH="/opt/ml/model:$PYTHONPATH" \
  -e GUNICORN_CMD_ARGS="--timeout 60 -k gevent" \
  "entity-extraction"
```
