OSError: [WinError 740] The requested operation requires elevation
我有一个简单的代码,其中有一个名为 "try.png" 的图像,我想使用 pytesseract 将它从图像转换为文本,但我遇到了一些代码问题。
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))
但是它给我一个错误。

关于如何克服这个错误的任何想法
tesseract-ocr-setup-4.00.00dev.exe
听起来像是安装程序 exe 而不是 tesseract 本身。检查你是否真的安装了 tesseract,如果没有,启动 exe 来安装。
Windows 从这里下载最新版本:
https://github.com/UB-Mannheim/tesseract/wiki
如果您仍然得到 OSError: [WinError 740] The requested operation requires elevation
,请尝试将 tesseract 可执行文件更改为 运行 作为管理员:Right Click tesseract.exe -> Properties -> Compability -> Check Run this program as an administrator -> OK
.
我猜你还没有在你的系统上安装 tesseract。 运行 tesseract-ocr-setup-4.00.00dev.exe
安装它并记下它的安装位置 ($tesseractLocation
)
如果在安装时遇到同样的错误,请使用管理员权限尝试 运行。
并替换
pytesseract.pytesseract.tesseract_cmd=r'tesseract-ocr-setup-4.00.00dev.exe'
和
pytesseract.pytesseract.tesseract_cmd=r'$tesseractLocation'
这将解决问题。在脚本中,你必须提到安装目录而不是安装文件。
尝试取消选中“运行此程序作为管理员”
尝试:
Right Click tesseract.exe -> Properties -> Compability -> Uncheck Run this program as an administrator -> apply
