介绍
飞桨（PaddlePaddle）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。
ORC 识别能力比较强
安装
安装 GPU 版本：
python -m pip install paddlepaddle-gpu==3.3.0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
安装 CPU 版本
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：
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：
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：
python -c "import paddle; paddle.utils.run_check()"
输出以下内容即代表成功：
(ocr) root@VM-0-80-ubuntu:/workspace# python -c "import paddle; paddle.utils.run_check()"
