python - 在python中阅读pdf

问题描述

我正在尝试根据期末考试成绩对我所在城市的学校进行比赛，数据在此处以 pdf 格式提供： https ://oke.wroc.pl/wp-content/uploads/library/File/pdfy/Powiaty_E8_192/0264.pdf

不幸的是，将 pdf 读取为 python 的简单解决方案不起作用。我努力了：

  1. PyPDF2包，但它给出了错误PdfReadWarning: Superfluous whitespace found in object header b'39' b'0' [pdf.py:1666]
  2. textract包，但它给出了错误stdout, stderr = pipe.communicate() UnboundLocalError: local variable 'pipe' referenced before assignment
  3. tabula包，但它给出了错误

得到标准错误：sty 27, 2020 5:33:46 PM org.apache.pdfbox.pdmodel.font.PDCIDFontType2
