# 部署Prometheus和Grafana（假设已安装）
git clone https://github.com/prometheus/prometheus.git
git clone https://github.com/grafana/grafana.git
# 启动服务
prometheus_start.sh
grafana_start.sh

# 安装Python和pip（如果尚未安装）
sudo apt-get update
sudo apt-get install python3 python3-pip
# 创建虚拟环境（推荐）
python3 -m venv deepseek_env
source deepseek_env/bin/activate
# 安装TensorFlow或PyTorch
pip install tensorflow  # 或者 pip install torch torchvision

pip install numpy scipy Pillow matplotlib h5py

# 克隆DeepSeek仓库
git clone https://github.com/DeepSeek/DeepSeek.git
# 进入仓库目录
cd DeepSeek
# 下载预训练模型（根据仓库中的说明操作）
wget https://example.com/path/to/deepseek_pretrained_model.zip
unzip deepseek_pretrained_model.zip

# 在DeepSeek目录中，可能需要编辑一个配置文件，例如config.py
# 设置模型路径、参数等

# 启动模型服务，例如使用Flask创建API
python app.py

# 安装支持GPU的TensorFlow
pip install tensorflow-gpu

# 使用TensorFlow Lite或TensorRT进行模型量化

# 启动Prometheus和Grafana服务
./prometheus --config.file=prometheus.yml
./grafana-server

# 在你的应用代码中添加Prometheus客户端代码来暴露指标

# 在你的模型服务代码中添加try-except块来处理可能的异常
