我尝试制作一个简单的OCR程序，但每当我运行它时，我都会收到以下错误。我甚至卸载了pytesser3并重新安装它但没有任何改变。我做错了什么？

import pytesser3
import Image
a = Image.open("C:\\Users\\dell\\Desktop\\test.png") 
b = pytesser3.image_to_string(a)
print(b)

这是test.png： https://i.stack.imgur.com/NBjbc.png

我做了你说的话，但现在我有一个不同的错误：

import pytesser3
import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:\\Users\\dell\\AppData\\Local\\Programs\\Python\\Python36-32\\Lib\\site-packages\\pytesseract'
a = Image.open("C:\\Users\\dell\\Desktop\\test.png")
b = pytesseract.image_to_string(a)
print(b)

Answer 1

您必须声明pytesseract路径：

import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract-
OCR/tesseract'

Answer 2

在pytesser3模块中打开“ init .py”文件。路径类似于“ c：\ .... \ Python \ site-packages \ pytesser3”或“ c：\ .... \ Python \ Lib \ site-packages \ pytesser3”内部。

然后将“ tesseract_exe_name =”的变量值修改为您的pytesseract路径，就像“ C：\ .... \ Python \ Lib \ site-packages \ pytesseract”或“ c：\ .... \ Python \ site-packages \ pytesseract“

它将解决问题。

Pytesser3中找不到错误
