Excel file returning empty value with no error [URGENT]

[adnanshafi99]

I have downloaded the English model and pasted it into the correct file. Still, the Excel output file is empty. Please help

D:\xyz\code\PaddleOCR\ppstructure\inference

This is the code that I used:

!git clone https://github.com/PaddlePaddle/PaddleOCR.git
!pip install paddleocr --upgrade
!pip install paddlepaddle

Run the Python script for table prediction

!python table\predict_table.py --det_model_dir=inference\en_PP-OCRv3_det_infer
--rec_model_dir=inference\en_ppocr_mobile_v2.0_table_rec_infer
--table_model_dir=inference\en_ppocr_mobile_v2.0_table_structure_infer

--rec_char_dict_path=..\ppocr\utils\dict\table_dict.txt
--table_char_dict_path=..\ppocr\utils\dict\table_structure_dict.txt
--output=.\output\table

Could you please provide the original image so we can test?

[adnanshafi99]

Here is the original Image. Thanks

[GreatV]

Got wrong result, it treated it as an equation. so the table is empty.

[adnanshafi99]

I see, so what could be the solution?

Can you try on this image as well?

[GreatV]

This looks good.

Try this code.

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

table_engine = PPStructure(show_log=True, image_orientation=True, lang="en")

save_folder = './output'
img_path = '338506733-1399c041-a326-41b9-83a8-60d7200a1958.png'
img = cv2.imread(img_path)
result = table_engine(img)
save_structure_res(result, save_folder,os.path.basename(img_path).split('.')[0])

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


font_path = 'doc/fonts/simfang.ttf' # PaddleOCR下提供字体包
image = Image.open(img_path).convert('RGB')
im_show = draw_structure_result(image, result,font_path=font_path)
im_show = Image.fromarray(im_show)
im_show.save('result.jpg')

Thank you so much. It's working as expected.

Hello @GreatV , After opening the res_0 notepad, it's showing all the confidence levels and boxes. Is it possible to convert the table only to HTML and Excel files?

Also, I have a PDF document that has 500 pages and I was wondering how to do table ocr in one go and have them converted to HTML and excel files.
