Python - pycharm - 使用OCR代码时出错

Question

我正在尝试从这里使用代码：

https://www.geeksforgeeks.org/python-reading-contents-of-pdf-using-ocr-optical-character-recognition/

# Import libraries 

from PIL import Image

import pytesseract

import sys

from pdf2image import convert_from_path

import os

# Path of the pdf 

PDF_file = "/Users/user1/Desktop/pdf1.pdf"

''' 

Part #1 : Converting PDF to images 

'''

# 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 

    # PDF page 2 -> page_2.jpg 

    # PDF page 3 -> page_3.jpg 

    # .... 

    # PDF page n -> page_n.jpg 

    filename = "page_" + str(image_counter) + ".jpg"

    # Save the image of the page in system 

    page.save(filename, 'JPEG')

    # Increment the counter to update filename 

    image_counter = image_counter + 1

''' 

Part #2 - Recognizing text from the images using OCR 

'''

3

# Variable to get count of total number of pages 

filelimit = image_counter - 1

# Creating a text file to write the output 

outfile = "/Users/user1/Desktop/ocr/pdf1.txt"

# Open the file in append mode so that  

# All contents of all images are added to the same file 

f = open(outfile, "a")

# Iterate from 1 to total number of pages 

for i in range(1, filelimit + 1):

    # Set filename to recognize text from

    # Again, these files will be: 

    # page_1.jpg 

    # page_2.jpg 

    # .... 

    # page_n.jpg 

    filename = "page_" + str(i) + ".jpg"

    # Recognize the text as string in image using pytesserct 

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