问题描述

我在python中使用PyTesseract for pdf。但是我在Windows 10中遇到权限错误。 我已经从https://github.com/UB-Mannheim/tesseract/wiki安装了tesseract-ocr-w64-setup-v5.0.0-alpha.20200328.exe 我也有poppler-20.09.0文件。我正在使用python 3.8.0 

import pdf2image
import PyPDF2
import os
try:
   from PIL import Image
except ImportError:
   import Image
import PyTesseract

PyTesseract.PyTesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR'

def pdf_to_img(pdf_file):
    print('pdf_file = ',pdf_file)
    return pdf2image.convert_from_path(pdf_file,dpi=200,fmt='jpg',poppler_path=r'F:\lokesh\resume_script\poppler-20.09.0\bin')


def ocr_core(file):
    text = PyTesseract.image_to_string(file,)
    return text


def print_pages(pdf_file):
    images = pdf_to_img(pdf_file)
    for pg,img in enumerate(images):
        print(ocr_core(img))


print_pages("aa.pdf")

当我运行这段代码时。它给出了这个错误。

Traceback (most recent call last):

  print_pages("aa.pdf")
