## Installation

```sh
conda create -n hipporag python=3.10
conda activate hipporag
pip install hipporag
```
Initialize the environmental variables and activate the environment:

```sh
export CUDA_VISIBLE_DEVICES=0,1,2,3
export HF_HOME=<path to Huggingface home directory>
export OPENAI_API_KEY=<your openai api key>   # if you want to use OpenAI model

conda activate hipporag
```

### Local Deployment (vLLM)

This simple example will illustrate how to use `hipporag` with any vLLM-compatible locally deployed LLM.

1. Run a local [OpenAI-compatible vLLM server](https://docs.vllm.ai/en/latest/getting_started/quickstart.html#quickstart-online) with specified GPUs (make sure you leave enough memory for your embedding model).

```sh
export CUDA_VISIBLE_DEVICES=0,1
export VLLM_WORKER_MULTIPROC_METHOD=spawn
export HF_HOME=<path to Huggingface home directory>

conda activate hipporag  # vllm should be in this environment
