安装 PaddleX 前请先确保您有基础的 <b>Python 运行环境</b>(注:当前支持Python 3.8 ~ Python 3.10下运行,更多Python版本适配中)。
=== "CPU"
```bash
python -m pip install paddlepaddle==3.0.0rc0 -i https://www.paddlepaddle.org.cn/packages/stable/cpu/
```
=== "CUDA 11.8"
```bash
python -m pip install paddlepaddle-gpu==3.0.0rc0 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
```
=== "CUDA 12.3"
```bash
python -m pip install paddlepaddle-gpu==3.0.0rc0 -i https://www.paddlepaddle.org.cn/packages/stable/cu123/
```

❗ 更多安装方式参考 PaddleX 安装教程
一行命令即可快速体验产线效果,统一的命令行格式为:
paddlex --pipeline [产线名称] --input [输入图片] --device [运行设备]
只需指定三个参数:
pipeline:产线名称input:待处理的输入文件(如图片)的本地路径或 URLdevice: 使用的 GPU 序号(例如gpu:0表示使用第 0 块 GPU),也可选择使用 CPU(cpu)!!! example "OCR相关产线命令行使用"
=== "通用OCR"
```bash
paddlex --pipeline OCR \
--input https://paddle-model-ecology.bj.bcebos.com/paddlex/imgs/demo_image/general_ocr_002.png \
--use_doc_orientation_classify False \
--use_doc_unwarping False \
--use_textline_orientation False \
--save_path ./output \
--device gpu:0
```

几行代码即可完成产线的快速推理,统一的 Python 脚本格式如下:
from paddlex import create_pipeline
pipeline = create_pipeline(pipeline=[产线名称])
output = pipeline.predict([输入图片名称])
for res in output:
res.print()
res.save_to_img("./output/")
res.save_to_json("./output/")
