## Model Deployment and Application Guide

## 1. Model Introduction

- Model name: BTRM_Qwen2_7b_0613

## 2. Environment Preparation

To be able to deploy and run the model smoothly, you need the following environment:

- Python>=3.11
- Anaconda

### Install dependencies

```bash
conda create --name BTRM_Qwen2_7b_0613
conda activate BTRM_Qwen2_7b_0613

# install torch official website https://pytorch.org/get-started/previous-versions/
# Install torch according to the cuda version of your graphics card, we recommend installing a newer version of torch.
pip install torch
# git clone https://github.com/allenai/reward-bench.git
# You must use the source code for testing
cd reward-bench-main
pip install -e .
# Requires transformers>=4.40.1
pip install transformers==4.40.1
pip install numpy pandas
# Measurement Code
# python scripts/run_rm.py --model={modelpath}
```

For the code that uses the model, see the following, which is how the model is commonly loaded
```bash
from transformers import AutoTokenizer, pipeline
import torch
