Question

我正在尝试将PDF转换为TEXT。但是我在PDFPage类中有问题。我已经搜索过了。但是我什么也没得到，这给了我下面的错误。我还为python 3.5安装了pdfminer.six，但仍然没有任何解决方案。请帮忙。

代码：

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
import os
import sys, getopt

#converts pdf, returns its text content as a string


 def extract_text_from_pdf(pdf_path):
    with open(pdf_path, 'rb') as fh:
        for page in PDFPage.get_pages(fh, 
                                      caching=True,
                                      check_extractable=True):
            resource_manager = PDFResourceManager()
            fake_file_handle = io.StringIO()
            converter = TextConverter(resource_manager, fake_file_handle, codec='utf-8', laparams=LAParams())
            page_interpreter = PDFPageInterpreter(resource_manager, converter)
            page_interpreter.process_page(page)

            text = fake_file_handle.getvalue()
            yield text

            # close open handles
            converter.close()
            fake_file_handle.close()

错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/system/anaconda3/lib/python3.6/site-packages/pdfminer/pdfpage.py", line 5, in <module>
    from .pdftypes import PDFObjectNotFound
ImportError: cannot import name 'PDFObjectNotFound'

Answer 1

在代码的开头添加以下行，然后进行尝试：

from io import StringIO

Answer 2

卸载pdfminer3k（如果已安装）

$ pip uninstall pdfminer3k

并使用以下命令安装pdfminer.six。

$ python -m pip install pdfminer.six

从.pdftypes导入PDFObjectNotFound ImportError：无法导入名称“ PDFObjectNotFound”
