### 安装

```bash linenums="1"
pip install paddleocr
```

### 使用

=== "文本检测+方向分类+文本识别"

    ```python linenums="1"
    from paddleocr import PaddleOCR, draw_ocr

    # Paddleocr supports Chinese, English, French, German, Korean and Japanese
    # You can set the parameter `lang` as `ch`, `en`, `french`, `german`, `korean`, `japan`
    # to switch the language model in order
    ocr = PaddleOCR(use_angle_cls=True, lang='en') # need to run only once to download and load model into memory
    img_path = 'PaddleOCR/doc/imgs_en/img_12.jpg'
    result = ocr.ocr(img_path, cls=True)
    for idx in range(len(result)):
        res = result[idx]
        for line in res:
            print(line)

    # draw result
    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='/path/to/PaddleOCR/doc/fonts/simfang.ttf')
    im_show = Image.fromarray(im_show)
    im_show.save('result.jpg')
    ```

    输出示例：

    ```python linenums="1"
    [[[442.0, 173.0], [1169.0, 173.0], [1169.0, 225.0], [442.0, 225.0]], ['ACKNOWLEDGEMENTS', 0.99283075]]

    [[[399.0, 398.0], [1204.0, 398.0], [1204.0, 433.0], [399.0, 433.0]], ['contributors whohave been involved in the', 0.9592447]]
