如何解决 TesseractNotFoundError? [英] How do I resolve a TesseractNotFoundError?

问题描述

我正在尝试在 Python 中使用 pytesseract，但最终总是出现以下错误:

I am trying to use pytesseract in Python but I always end up with the following error:

    raise TesseractNotFoundError()
pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path

然而，pytesseract 和 Tesseract 安装在我的系统上.

However, pytesseract and Tesseract are installed on my system.

产生此错误的示例代码:

Example code that produces this error:

import cv2
import pytesseract

img = cv2.imread('1d.png')
print(pytesseract.image_to_string(img))

How do I resolve this TesseractNotFoundError?

推荐答案

我收到这个错误是因为我用 pip 安装了 pytesseract 但忘记安装二进制文件.

在 Linux 上

I got this error because I installed pytesseract with pip but forget to install the binary.

sudo apt update
sudo apt install tesseract-ocr
sudo apt install libtesseract-dev

在 Mac 上

brew install tesseract

在 Windows 上

从 https://github.com/UB-Mannheim/tesseract/wiki 下载二进制文件.然后将 pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe' 添加到您的脚本中.(如有必要，替换tesseract二进制文件的路径)

On Windows

download binary from https://github.com/UB-Mannheim/tesseract/wiki. then add pytesseract.pytesseract.tesseract_cmd = 'C:\\Program Files (x86)\\Tesseract-OCR\\tesseract.exe' to your script. (replace path of tesseract binary if necessary)
