关于图片转文字的问题

1248956321

代码如下：
import pytesseract as py
from PIL import Image

path = r'f:\777\66\55\Tesseract-OCR\tesseract.exe'

py.pytesseract.tesseract_cmd = path

img = Image.open(r'f:\777\66\shot\my_shot.png')

text = py.image_to_string(img)

print(text)

能运行只是最后会出错
Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    py.image_to_string(img)
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python38-32\lib\site-packages\pytesseract\pytesseract.py", line 409, in image_to_string

求哪位大师能看一下是什么原因？
