===安装===
使用[[pip]]安装PaddlePaddle：
<syntaxhighlight lang="bash" >
# 仅使用CPU运算，安装paddlepaddle
python3 -m pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple

# 使用GPU加速，安装paddlepaddle-gpu，需要先安装CUDA9或CUDA10
python3 -m pip install paddlepaddle-gpu -i https://mirror.baidu.com/pypi/simple
</syntaxhighlight>

使用[[pip]]安装PaddleOCR：
 pip install paddleocr

===安装常见错误===
* 错误1，缺少软件。
<syntaxhighlight lang="text" >
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
</syntaxhighlight>
在Windows官网https://learn.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist，选择需要版本安装，重启计算机。检查是否安装成功，可以在cmd中查询注册表，如vc++ 14.0 x64版本
 reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\14.0\VC\Runtimes\X64

* 错误2，某个软件包版本不合适。
<syntaxhighlight lang="text" >
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
paddlepaddle 2.4.2 requires protobuf<=3.20.0,>=3.1.0, but you have protobuf 3.20.3 which is incompatible.
</syntaxhighlight>
卸载当前版本的软件，重新安装合适版本：
<syntaxhighlight lang="python" >
pip uninstall -y protobuf
pip install protobuf==3.20.0
</syntaxhighlight>
==快速开始==
===Python中使用===
首次使用PaddleOCR，会自动下载ppocr轻量级模型作为默认模型。
<syntaxhighlight lang="python" >
from paddleocr import PaddleOCR, draw_ocr

# Paddleocr目前支持的多语言语种可以通过修改lang参数进行切换
# 例如`ch`, `en`, `fr`, `german`, `korean`, `japan`
ocr = PaddleOCR(use_angle_cls=True, lang="ch") 
img_path = './test.jpg'
result = ocr.ocr(img_path, cls=True)
for idx in range(len(result)):
    res = result[idx]
    for line in res:
        print(line)

# 显示结果，存储到result.jpg
# 如果本地没有simfang.ttf，可以在doc/fonts目录下下载
from PIL import Image
result = result[0]
image = Image.open(img_path).convert('RGB')
boxes = [line[0] for line in result]
txts = [line[1][0] for line in result]
scores = [line[1][1] for line in result]
im_show = draw_ocr(image, boxes, txts, scores, font_path='doc/fonts/simfang.ttf')
im_show = Image.fromarray(im_show)
im_show.save('result.jpg')
</syntaxhighlight>
