使用python3从PDF中提取文本

Question

我试图从PDF文件中的文本使用slate模块，如本

$sudo pip install https://codeload.github.com/timClicks/slate/zip/master
Collecting https://codeload.github.com/timClicks/slate/zip/master

  Found existing installation: slate 0.3
    Uninstalling slate-0.3:
      Successfully uninstalled slate-0.3
  Running setup.py install for slate ... done
Successfully installed slate-0.5.2

而我想：

#!/usr/bin/python3
import slate

with open('/var/tmp/PhysRevB.93.014203.pdf') as fp:
    doc = slate.PDF(fp)
print(len(doc))
print(doc[0])

这是给我的错误：

$python3 tstslt.py 
Traceback (most recent call last):
  File "tstslt.py", line 2, in <module>
    import slate
  File "/usr/lib/python3.5/site-packages/slate/__init__.py", line 66, in <module>
    from .classes import PDF
  File "/usr/lib/python3.5/site-packages/slate/classes.py", line 25, in <module>
    import utils
ImportError: No module named 'utils'

我可以用PyPDF2，但如果看板岩是更好的提取文本。

Answer 1

据qazxsw POI平板的一个依赖（pdfminer）不支持Python3

(...)

所需不起作用，因为它是目前使用python 3.5不兼容的“pdfminer”。

它说，所以他们的自述：

this issue

“安装Python 2.6或更高版本。（Python 3中不被支持。）”

Answer 2

https://github.com/euske/pdfminer是原始slate3k为python3的叉子。

您可以使用slate安装slate3k
