Python 为什么它不起作用？Pytesharact不工作问题

我认为Pytesharact不起作用了还是怎么了？我已经安装了tessaract。

pip安装pytesseract

已满足要求：c:\programdata\anaconda3\lib\site包中的PyteSeract（0.3.6） 已满足要求：c:\programdata\anaconda3\lib\site包中的枕头（来自pytesseract）（7.0.0） 注意：您可能需要重新启动内核以使用更新的软件包

系统规格： Windows 10、Python 3.7、anaconda 1.9.12

# Import libraries 
from PIL import Image

# Path of the pdf 
PDF_file = "E:/python_test/test.pdf"

# Store all the pages of the PDF in a variable 
pages = convert_from_path(PDF_file, 500) 

# Counter to store images of each page of PDF to image 
image_counter = 1

# Iterate through all the pages stored above 
for page in pages: 

    # Declaring filename for each page of PDF as JPG 
    # For each page, filename will be: 
    # PDF page 1 -> page_1.jpg

    # Save the image of the page in system 
    page.save(filename, 'JPEG') 

    # Increment the counter to update filename

    text = str(((pytesseract.image_to_string(Image.open(filename))))) 

    # The recognized text is stored in variable text 
    # Any string processing may be applied on text 
    # Here, basic formatting has been done: 
    # In many PDFs, at line ending, if a word can't 
    # be written fully, a 'hyphen' is added. 
    # The rest of the word is written in the next line 
    # Eg: This is a sample text this word here GeeksF- 
    # orGeeks is half on first line, remaining on next. 
    # To remove this, we replace every '-\n' to ''. 
    text = text.replace('-\n', '')   

    # Finally, write the processed text to the file. 
    f.write(text) 

# Close the file after writing all the text. 
f.close()
