# PaddlePaddle（Python）
|
||
|
||
[飞桨（PaddlePaddle）](https://www.paddlepaddle.org.cn/)以百度多年的深度学习技术研究和业务应用为基础，集深度学习核心训练和推理框架、基础模型库、端到端开发套件、丰富的工具组件于一体，是中国首个自主研发、功能丰富、开源开放的产业级深度学习平台。 飞桨于2016 年正式开源，是主流深度学习框架中一款完全国产化的产品。

|
||
## 安装 PaddlePaddle
|
||
|
||
参考网站：https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/develop/install/pip/linux-pip.html
|
||
|
||
安装 GPU 版本：
|
||
```bash
|
||
python -m pip install paddlepaddle-gpu==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
|
||
```
|
||
|
||
安装 CPU 版本
|
||
```bash
|
||
python -m pip install paddlepaddle==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
|
||
```
|
||
|
||
如果是 **GPU版本** 需要注意自己的 `CUDA` 版本，不要过高即可，查看命令：
|
||
|
||
```bash
|
||
nvidia-smi
|
||
```
|
||
|
||
输出如下：
|
||
|
||
```

|
||
当前电脑的 CUDA 版本为 12.0，所以下载 小于等于 12.0 版本的 `paddlepaddle` 即可：
|
||
|
||
```bash
|
||
python -m pip install paddlepaddle-gpu==3.1.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
|
||
```
|
||
|
||
检查是否安装成功：
|
||
|
||
```bash
|
||
python -c "import paddle; paddle.utils.run_check()"
|
||
```
|
||
|
||
输出以下内容即代表成功：
|
||
|
||
```
