Summary](#3-summary) ## 1. Installation ### 1.1 Install PaddlePaddle > If you do not have a Python environment, please refer to [Environment Preparation](./environment_en.md). - If you have CUDA 9 or CUDA 10 installed on your machine, please run the following command to install ```bash python3 -m pip install paddlepaddle-gpu ``` - If you have no available GPU on your machine, please run the following command to install the CPU version ```bash python3 -m pip install paddlepaddle ``` For more software version requirements, please refer to the instructions in [Installation Document](https://www.paddlepaddle.org.cn/install/quick) for operation. ### 1.2 Install PaddleOCR Whl Package ```bash pip install "paddleocr>=2.0.1" # Recommend to use version 2.0.1+ ``` - **For windows users:** If you getting this error `OSError: [WinError 126] The specified module could not be found` when you install shapely on windows. Please try to download Shapely whl file [here](http://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely). Reference: [Solve shapely installation on windows](https://stackoverflow.com/questions/44398265/install-shapely-oserror-winerror-126-the-specified-module-could-not-be-found) - **For layout analysis users**, run the following command to install **Layout-Parser** ```bash pip3 install -U https://paddleocr.bj.bcebos.com/whl/layoutparser-0.0.0-py3-none-any.whl ``` ## 2. Easy-to-Use ### 2.1 Use by Command Line PaddleOCR provides a series of test images, click [here](https://paddleocr.bj.bcebos.com/dygraph_v2.1/ppocr_img.zip) to download, and then switch to the corresponding directory in the terminal ```bash cd /path/to/ppocr_img ``` If you do not use the provided test image, you can replace the following `--image_dir` parameter with the corresponding test image path #### 2.1.1 Chinese and English Model * Detection, direction classification and recognition: set the parameter`--use_gpu false` to disable the gpu device ```bash paddleocr --image_dir ./imgs_en/img_12.jpg --use_angle_cls true --lang en --use_gpu false ``` Output will be a list, each item contains bounding box, text and recognition confidence ```bash [[[441.0, 174.0], [1166.0, 176.0], [1165.0, 222.0], [441.0, 221.0]], ('ACKNOWLEDGEMENTS', 0.9971134662628174)] [[[403.0, 346.0], [1204.0, 348.0], [1204.0, 384.0], [402.0, 383.0]], ('We would like to thank all the designers and', 0.9761400818824768)] [[[403.0, 396.0], [1204.0, 398.0], [1204.0, 434.0], [402.0, 433.0]], ('contributors who have been involved in the', 0.9791957139968872)] ...... ``` * Only detection: set `--rec` to `false` ```bash paddleocr --image_dir ./imgs_en/img_12.jpg --rec false ``` Output will be a list, each item only contains bounding box ```bash [[397.0, 802.0], [1092.0, 802.0], [1092.0, 841.0], [397.0, 841.0]] [[397.0, 750.0], [1211.0, 750.0], [1211.0, 789.0], [397.0, 789.0]] [[397.0, 702.0], [1209.0, 698.0], [1209.0, 734.0], [397.0, 738.0]] ...... ``` * Only recognition: set `--det` to `false` ```bash paddleocr --image_dir ./imgs_words_en/word_10.png --det false --lang en ``` Output will be a list, each item contains text and recognition confidence ```bash ['PAIN', 0.9934559464454651] ``` If you need to use the 2.0 model, please specify the parameter `--ocr_version PP-OCR`, paddleocr uses the PP-OCRv3 model by default(`--ocr_version PP-OCRv3`). More whl package usage can be found in [whl package](./whl_en.md) #### 2.1.2 Multi-language Model PaddleOCR currently supports 80 languages, which can be switched by modifying the `--lang` parameter. ``` bash paddleocr --image_dir ./doc/imgs_en/254.jpg --lang=en ```
