在Pytesser3中找不到错误

Question

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

我试图制作一个简单的OCR程序，但是每当我运行它时，我都会得到以下错误。我甚至已经卸载并重新安装了pytesser3，但是没有什么改变。我做错了什么？

Traceback (most recent call last):
  File "C:/Users/dell/Desktop/crossword.py", line 4, in <module>
    b = pytesser3.image_to_string(a)

下面是test.png：https://i.stack.imgur.com/NBjbc.png

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)

我照你说的做了，但现在我犯了一个不同的错误：

Traceback (most recent call last):
  File "C:/Users/dell/Desktop/crossword.py", line 6, in <module>
b = pytesseract.image_to_string(a)
  File "C:\Users\dell\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pytesseract\pytesseract.py", line 122, in image_to_string

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

在模块中打开“.py”文件。路径应该是“c：.\Python\site-packages\pytesser3 3”，或者在“c：.Python\Lib\site-packages\pytesser3 3”中。

并将"tesseract_exe_name =“的变量值修改为pytesseract路径，该路径类似于”C：.\Python\Lib\site-packages\pytesseract“或”c：.\Python packages\pytesseract“

它将解决这个问题。
