pdfminer package: can't find exgtract_text function - Pavel_47 - Jan-25-2021

Hello,

Using pdfminer package I faced the following problem:

>>> from pdfminer import high_level
>>> extracted_text = high_level.extract_text(full_filename_inp, "", [4])
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    extracted_text = high_level.extract_text(full_filename_inp, "", [4])
AttributeError: module 'pdfminer.high_level' has no attribute 'extract_text'

But, according to documentation the function extract_text does exist in pdfminer package.
pdfminer package
Any suggestions ?
Thanks

The document that you point to is pdfminer-six.

Since 2020, the original pdfminer is dormant, and pdfminer.six is the fork which Euske recommends if you need an actively maintained version of pdfminer.

Which do you have installed?

install for pdfminer-six is pip install pdfminer.six

First I installed pdfminer:

Then I saw this issue and installed pdfminer.six:

Output:pavel@ALABAMA:~$ pip3 install pdfminer.six

Requirement already satisfied: sortedcontainers in ./.local/lib/python3.6/site-packages (from pdfminer.six) (2.1.0)
pavel@ALABAMA:~$

So I don't know what's really going on ... which one is imported.

uninstall both and install just pdfminer.six

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

Concerning Error message:

Should I change beautifulsoup4 4.8.1 to beautifulsoup4 4.8.0 ?
Should I install 20181108 instead of 20201018 ?

After pdfminer.six reinstall, the initial example works.
Thanks.

Do not change anything,try if works as it probably dos now.
It's highly unlike that one version number of Beautifulsoup will break anything in this package,
as BS it's not even in required packed for pdfminer.six.

Here a quick tutorial on using virtual environment,it's build into Python an just take a minute to do.
This solve all dependency conflicts as none what you installed before is been looked at or used,it's now all new.

When do pip list only packages in this environment is shown as it's isolated from what's install on OS level.
