pytesseract throw FileNotFoundError：[WinError 2]系统找不到指定的文件

Question

我在python 3.x中使用pytesseract并尝试将图像转换为文本。

运行代码：

from pytesseract import image_to_string
from PIL import Image

im = Image.open('image.bmp')
print(im)
print(image_to_string(im)

给出输出：

>>> ================================ RESTART ================================
>>> 
<PIL.BmpImagePlugin.BmpImageFile image mode=RGB size=563x558 at 0x2D9C350>
Traceback (most recent call last):
  File "C:\Users\ADMIN\Desktop\image.py", line 6, in <module>
    s= image_to_string(im)

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

PIL似乎正在加载图像就好了，但是pytesseract正在抛出FileNotFoundError而我不知道为什么。任何帮助非常感谢！
