OSError: [WinError 740] 请求的操作需要提升 [英] OSError: [WinError 740] The requested operation requires elevation

问题描述

我有一个简单的代码，其中包含一个名为try.png"的图像，我想使用 pytesseract 将其从图像转换为文本，但代码存在一些问题.

I am having a simple code which has an image called "try.png" and I want to convert it from Image to Text using pytesseract but I am having some issues with the code.

import cv2
import pytesseract
pytesseract.pytesseract.tesseract_cmd=r'tesseract-ocr-setup-4.00.00dev.exe'
img = cv2.imread('try.png')
img= cv2.cvtColor(img,cv2.COLOR_BGR2RGB)
print(pytesseract.image_to_string(img))

但它给了我一个错误.

关于如何克服这个错误的任何想法

Any idea on how to over come this error

推荐答案

tesseract-ocr-setup-4.00.00dev.exe 听起来像一个安装 exe 而不是 tesseract 本身.检查您是否实际安装了tesseract，如果没有启动exe进行安装.

tesseract-ocr-setup-4.00.00dev.exe sounds like a setup exe and not the tesseract itself. Check if you have actually installed tesseract and if not launch the exe to install.

对于 Windows，从这里下载最新版本:https://github.com/UB-Mannheim/tesseract/wiki

For Windows download the latest version from here: https://github.com/UB-Mannheim/tesseract/wiki

如果您仍然遇到 OSError: [WinError 740] 请求的操作需要提升 尝试将 tesseract 可执行文件更改为以管理员身份运行:右键单击 tesseract.exe ->属性 ->兼容性 ->选中以管理员身份运行此程序 ->好的 .

If you still get OSError: [WinError 740] The requested operation requires elevation try changing the tesseract executable to run as admin: Right Click tesseract.exe -> Properties -> Compability -> Check Run this program as an administrator -> OK .
