PPStructure.save_structure_res设置return_ocr_result_in_table=True JSON报错

[zealzeng]

pip install paddlepaddle -i https://mirror.baidu.com/pypi/simple
pip install "paddleocr>=2.6.0.3" -i https://mirror.baidu.com/pypi/simple
pip install paddleclas>=2.4.3 -i https://mirror.baidu.com/pypi/simple

官方例子， 主要是修改了result = table_engine(img, True)想获取返回的字符

import os
import cv2
from paddleocr import PPStructure, draw_structure_result, save_structure_res

table_engine = PPStructure(show_log=True)
save_folder = './output'
img_path = './doc/table/table.jpg'
img = cv2.imread(img_path)
result = table_engine(img, True)
save_structure_res(result, save_folder, os.path.basename(img_path).split('.')[0])

for line in result:
    line.pop('img')
    print(line)

具体报错如下：

Traceback (most recent call last):
  File "D:\project\pp-structure\main.py", line 12, in <module>
    save_structure_res(result, save_folder, os.path.basename(img_path).split('.')[0])
  File "D:\project\pp-structure\venv\lib\site-packages\paddleocr\ppstructure\predict_system.py", line 199, in save_structure_res
    f.write('{}\n'.format(json.dumps(region)))
  File "D:\Python\Python39\lib\json\__init__.py", line 231, in dumps
    return _default_encoder.encode(obj)
  File "D:\Python\Python39\lib\json\encoder.py", line 199, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "D:\Python\Python39\lib\json\encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
  File "D:\Python\Python39\lib\json\encoder.py", line 179, in default
    raise TypeError(f'Object of type {o.__class__.__name__} '
TypeError: Object of type ndarray is not JSON serializable

ndarray json dump的出错了， 默认table_engine(img)没问题

感谢反馈，已经修复 PR，可以更新到2.6.1.2试试，或者手动编译安装试试
