我无法使用pytesseract&;从.tif图像文件中提取文本;Python中的PIL。 它适用于.png、.jpg图像文件,它只在.tif图像文件中给出错误。 我使用的是Python 3.7.1版本
在为.tif图像文件运行Python代码时,它给出了以下错误。请让我知道我做错了什么

下面是它的Python代码
#Import modules
from PIL import Image
import pytesseract
# Include tesseract executable in your path
pytesseract.pytesseract.tesseract_cmd = r"C:\Program Files\Tesseract-OCR\tesseract.exe"
# Create an image object of PIL library
image = Image.open(r'C:\Users\u88ltuc\Desktop\12110845-e001.tif')
# pass image into pytesseract module
image_to_text = pytesseract.image_to_string(image, lang='eng')
# Print the text
print(image_to_text)
以下是tif图像及其链接:
首先,您应该更改图像扩展名。 这或许可以解决您的问题:
或者,如果您不介意您的桌面有两张相同的图片,您不需要
