anaconda3+ paddleOCR安裝使用

老實說，官網文檔有點雲山霧罩。

windows下又不讓用nvidia-docker，只好anaconda的方式裝

綜合

https://www.paddlepaddle.org.cn/install/quick

和

https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_en/installation_en.md

 

配置conda 國內鏡像

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ conda config --set show_channel_urls yes

 

1 建立3.7虛環境

conda create --name paddle python=3.7
activate paddle

一定要有版本

2 安裝 paddlepaddle-gpu 2.0.0版

只能用pip從百度的鏡像里安裝，conda和公網的pypi都沒有這個版本

百度的鏡像里只有2.0.0a0， docker版才有2.0.0b0

python -m pip install paddlepaddle-gpu==2.0.0a0 -i https://mirror.baidu.com/pypi/simple

3.7下只有 2.0.0a0 

 

3 paddleOCR

3.1 下載源碼，安裝依賴

git clone https://gitee.com/paddlepaddle/PaddleOCR
cd PaddleOCR
pip install -r requirments.txt

3.2 手動下載安裝shapely

https://www.lfd.uci.edu/~gohlke/pythonlibs/#shapely

3.3 手動解改名、解壓縮、復制dll！

https://github.com/PaddlePaddle/PaddleOCR/issues/212

從您提供的網址下載了 Shapely-1.7.0-cp39-cp39-win_amd64.whl，pip install 此whl文件不成功。

於是更名為Shapely-1.7.0-cp39-cp39-win_amd64.rar，

然后解壓縮，從其子目錄shapely\DLLs\中找到geos_c.dll，並將geos_c.dll拷貝到conda的環境（我的命名是ocr）目錄 C:\Users\myusername\Miniconda3\envs\ocr\Library\bin中。問題解決。

 

3.4 修改PaddleOCR/paddleocr.py

然后參考

https://github.com/PaddlePaddle/PaddleOCR/issues/832

在PaddleOCR/paddleocr.py中，找到def parse_args():

在下面加入下面這行

parser.add_argument("--use_pdserving", type=bool, default=False)

 

否則后面運行會報錯

 

Namespace(cls=False, cls_batch_num=30, cls_image_shape='3, 48, 192', cls_model_dir='C:\\Users\\xuqinghan/.paddleocr/cls', cls_thresh=0.9, det=True, det_algorithm='DB', det_db_box_thresh=0.5, det_db_thresh=0.3, det_db_unclip_ratio=2.0, det_east_cover_thresh=0.1, det_east_nms_thresh=0.2, det_east_score_thresh=0.8, det_max_side_len=960, det_model_dir='C:\\Users\\xuqinghan/.paddleocr/det', enable_mkldnn=False, gpu_mem=8000, image_dir=None, ir_optim=True, label_list=['0', '180'], lang='ch', max_text_length=25, rec=True, rec_algorithm='CRNN', rec_batch_num=30, rec_char_dict_path='./ppocr/utils/ppocr_keys_v1.txt', rec_char_type='ch', rec_image_shape='3, 32, 320', rec_model_dir='C:\\Users\\xuqinghan/.paddleocr/rec/ch', use_angle_cls=False, use_gpu=True, use_space_char=True, use_tensorrt=False, use_zero_copy_run=False)

if args.use_pdserving is False:
AttributeError: 'Namespace' object has no attribute 'use_pdserving'

3.5 安裝

cd PaddleOCR
python setup.py install

 

最終 運行個demo 應該不會報錯了

import os
from paddleocr import PaddleOCR, draw_ocr

if __name__ == '__main__':

    PATH_IMG_IN = './in'
    filename = os.path.join(PATH_IMG_IN, '1.png')

    ocr = PaddleOCR() # need to run only once to download and load model into memory
    start = time.perf_counter()
    result = ocr.ocr(filename, rec=False)
    end = time.perf_counter()
    print('檢測文字區域 耗時{}'.format(end-start))
    #每個矩形，從左上角順時針排列

    for rect1 in rects:
        print(rect1)

 

 

小結：

       文檔混亂，安裝過程到處是坑。但是看在效果還湊合的份上，湊合用吧
