【问题描述】：

我在 Python 中使用 pytesseract 来获取 pdf。但我在 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")

我们如何在 windows 中解决这个错误

【问题讨论】：

您的tesseract_cmd 似乎太短了。缺少二进制文件？

当我添加 pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe' 然后它给出一个错误 pytesseract.pytesseract.TesseractError: (1, 'Error opening data file C:/Program Files (x86)/Tesseract-OCR/tessdata/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language \'eng\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')

你还有一个错误。

如何解决这个错误

【参考方案1】：

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

需要

pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe'
