读取PDF文件时出现断言错误 python - pypdf2

Question

当我试图阅读一个PDF文件时，我得到了以下错误。

代码。

from PyPDF2 import PdfFileReader
import os

os.chdir("Path to dir")

pdf_document = 'sample.pdf'
pdf = PdfFileReader(pdf_document,'rb') #Error here

错误。

Traceback (most recent call last):
File "/home/krishna/PycharmProjects/sample/sample.py", line 9, in
pdf = PdfFileReader(filehandle)
File "/home/krishna/PycharmProjects/AI_DRC/venv/lib/python3.6/site-packages/PyPDF2/pdf.py", line 1084, in init
self.read(stream)
File "/home/krishna/PycharmProjects/AI_DRC/venv/lib/python3.6/site-packages/PyPDF2/pdf.py", line 1838, in read
assert start >= last_end
AssertionError

注意：文件大小为18MB

我在这里写了这个，它对我来说完全有效，pdf在同一个文件夹里，你也可以使用os来获取字符串类型的路径值。

import PyPDF2

pdf_file = PyPDF2.PdfFileReader("Sample.pdf")#addressing the file, you can use os method it works on that as well

page_content = pdf_file.getPage(0).extractText()# here I get the psge number one(index zero) and then extracted its content

print(page_content)#you can then do whatever you want with it

我认为你的程序的问题在于那个 "rb "的东西，你在正常的文件处理中使用它，PyPDF2已经有了PdfFileReader、PdfFileWriter和PdfFileMerger的方法，希望对你有所帮助如果你反驳任何问题，只需提及，我会尝试着去回复它。
