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)

我试图做一个简单的OCR程序，但每当我运行它，我得到以下错误。我甚至卸载了pytesser3并重新安装了它，但是没有任何改变。我做错什么了？在

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，但现在我有了另一个错误：

Answer 1

必须声明pytesseract路径：

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

Answer 2

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

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\site packages\pytesseract”

它将解决这个问题。在
