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，但每当我运行它时，都会出现以下错误。我什至卸载了 pytesser3 并重新安装了它，但没有任何改变。我究竟做错了什么？

Traceback (most recent call last):
  File "C:/Users/dell/Desktop/crossword.py", line 4, in <module>
    b = pytesser3.image_to_string(a)
  File "C:\Users\dell\AppData\Local\Programs\Python\Python36-32\lib\site-    packages\pytesser3\__init__.py", line 30, in image_to_string

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)

我做了你说的，但现在我有一个不同的错误：

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

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

并将“tesseract_exe_name =”的变量值修改为您的 pytesseract 路径，如“C:\....\Python\Lib\site-packages\pytesseract”或“c:\....\Python\site -包\pytesseract"

它将解决问题。

您必须声明 pytesseract 路径：

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