pytesseract在Windows 10：

Question

我在Windows上使用10 x64 pytesseract錯誤打開數據文件，蟒蛇是3.5.2 x64，正方體是4.0，代碼如下：

# -*- coding: utf-8 -*- 

try: 
    import Image 
except ImportError: 
    from PIL import Image 
import pytesseract 


print(pytesseract.image_to_string(Image.open('d:/testimages/name.gif'), lang='chi_sim')) 

錯誤：

Traceback (most recent call last): 
    File "D:/test.py", line 10, in <module> 
    print(pytesseract.image_to_string(Image.open('d:/testimages/name.gif'), lang='chi_sim')) 
    File "C:\Users\dell\AppData\Local\Programs\Python\Python35\lib\site-packages\pytesseract\pytesseract.py", line 165, in image_to_string 
    raise TesseractError(status, errors) 
pytesseract.pytesseract.TesseractError: (1, 'Error opening data file \\Program Files (x86)\\Tesseract-OCR\\tessdata/chi_sim.traineddata') 

C:\Program Files (x86)\Tesseract-OCR\tessdata，像這樣：

爲什麼？

Answer 1

設置TESSDATA_PREFIX環境變量C:\Program Files (x86)\Tesseract-OCR\

Answer 2

如果你有一個像tessdata錯誤：「錯誤打開數據文件...」

tessdata_dir_config = '--tessdata-dir "<replace_with_your_tessdata_dir_path>"' 
# Example config: '--tessdata-dir "C:\\Program Files (x86)\\Tesseract-OCR\\tessdata"' 
# It's important to add double quotes around the dir path. 

pytesseract.image_to_string(image, lang='chi_sim', config=tessdata_dir_config)
