Import error

[Schabernack]

When trying to import slate, the following error message occurs. pdfminer and slate have been installed via pip.

Using Windows XP and Python 2.7

>>> import slate
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "c:\meins\programm\python\hier\lib\site-packages\slate\__init__.py", line 48, in <module>

from pdfminer.pdfparser import PDFParser, PDFDocument
ImportError: cannot import name PDFDocument

Looking at the pdfminer website, i found the following command that works:

from pdfminer.pdfdocument import PDFDocument

Maybe pdfminer changed their API?

[timClicks]

Hrm... ok, I'll look into this. PDFMiner has changed its API, so we'll need to do some version checking.

[daryltucker]

I was able to sudo pip install --upgrade --ignore-installed slate==0.3 pdfminer==20110515, which are compatible versions.

Also affects opensyllabus

[timClicks]

Thanks for the workaround.

[timClicks]

Okay, I've added a try except block, which should allow people to use whichever version of pdfminer they want.

This hasn't been uploaded to PyPI yet.

[morninj]

Ideally, Slate would grab the correct version of PDFMiner when the user installs Slate from PyPI. See http://www.scotttorborg.com/python-packaging/dependencies.html.

[timClicks]

Thanks @morninj. Specifying an exact version in setup.py seems like a good idea.

[timClicks]

Closing as I've actually decided that slate should try to support as much functionality as possible, rather than requiring a specific version. It's aim is to simplify things for the end user and not add bureaucracy. That makes slate more complex, but it's quite a small package so no bit deal really.

Please reopen if this is ImportError is still happening.

[timClicks]

Received an email about this issue. Perhaps we should force a specific version?

This issue still exists until today. I used the workaround and it is working but the question is with this
work around we will never be able to use newer versions of pdfminer with slate. Slate is an awesome > work. So it would be great to let it keep up with the newer versions of pdfminer.

What do you think?

Will reopen issue for a few months and will wait for feedback.

[rajat4493]

The issue still persists, even after upgrading the slate and pdfminer. Any updates ?

[imichaelmoore]

+1

[timClicks]

@rajat4493 @imichaeldotorg Could you two try pip install -U slate now and see if there has been any improvement in the recent release I pushed to PyPI today.

If not, could you please report the version number of your PDFMiner package using the following:

>>> import pdfminer
>>> pdfminer.__version__
'20140328'

[imichaelmoore]

Still does not work for me.

I created a fresh Ubuntu 14.04 environment, upgraded PIP, and ran pip install -U slate.

Commenting to say I am also having the ImportError with a completely fresh pip, Python 2.6, PDFMiner, and slate install. Are there any current known workarounds, such as the one previously posted?

Those are different machines, but I had this working on the El Capitan machine before
on newest releases of pdfminer and slate. Suspect that the upgrade to El Capitan was
what broke the setup (does the python version have a role in this...?)

[nmstoker]

I'm also getting this. My set up is Windows 7, with a Conda install of Python 2.7.

pdfminer.__version__
'20140328'

If I try import slate I get:

[boydjohnson]

I got the same error and eliminated it by going back to pdfminer==20100104. But then it gave me another error when I tried to use slate.PDF, so I switched to pdfminer==20100424 and was able to get text from a pdf.

I don't know if there is a newer pdfminer that works, but this was my workaround.

[user32000]

Same here, also on El Capitan, and with fresh pip installs of pdfminer (pdfminer-20140328) and slate (slate-0.3)

[snake-plissken]

This error seems to still exists, at least if you use pip to install. I think it has to do with an out of date setup.py file at pypi, as pip installs version 0.3 even though the latest version is 0.5.2. Version 0.3 doesn't have the changes to the import statements that rectify things.

Some of the verbose output from pip:

tried installing from pip resulting in the same condition(s) as mentioned above. Then, pulled down the slate-master.zip and ran setup.py.
Results, installed version 0.52 and was able to successfully import. This is on win 8.1, python 3.5.1

[rdpickard]

Hi all,

Not sure if editing the slate.py is an option for people's environment, but if you change

line 3

from pdfminer.pdfparser import PDFParser, PDFDocument

to

from pdfminer.pdfparser import PDFParser
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfpage import PDFPage

line 38

        self.doc = PDFDocument()

to

        self.doc = PDFDocument(self.parser)

comment out lines 40 & 41

line 49

            for page in self.doc.get_pages():
                self.append(self.interpreter.process_page(page))

to

            for page in PDFPage.create_pages(self.doc):
                self.append(self.interpreter.process_page(page))

it works.

Here are the versions of libraries I am using

cssselect==0.9.1
lxml==3.6.0
pdfminer==20140328
pyquery==1.2.13
slate==0.3
wheel==0.24.0

[rishabh-joshi]

Install slate using the setup.py file from the repository instead of PyPI. Even though PyPI claims to have version 0.5.2, it installs 0.3 instead. You can verify this by checking the version of slate installed using the following command
pip freeze
Everything works fine with the latest version of slate.

[gagandeep]

@rishabh-joshi slate installed by pip was 0.3. Got it resolved by following,

pip uninstall slate
pip install git+https://github.com/timClicks/slate.git

That might help someone else also.

in windows i don't have git installed, i downloaded the zip, cd in master and run "python setup.py install"

[TheCthulhuKid]

@benjaminweb in classes change import utils to from . import utils and it will work no problem. I think someone has already submitted a pull request.

Edit: I'm on Windows 10 Professional using Python 3.5.2

[xgeric]

@benjaminweb A little supplement for @gileadslostson's answer. Try to change import utils to import slate.utils, and that works for me on Mac, python 3.5.2.

Also, the sample code might come across a 'UnicodeDecodeError' when executing with open(filepath) as f: slate.PDF(f). Try with open(filepath, 'rb') as f instead, which would read the pdf file in binary.

Hope it helps : )

For both python2 and python3 I receive an import error

It doesn't matter which PDFminer I use either i started with this one https://github.com/euske/pdfminer received the error so install this one and still got error. https://github.com/goulu/pdfminer

Note with the second I used python3 setup.py install.

[ghost]

@gileadslostson @xgeric @benjaminweb
I changed the classes.py line 25 to from . import utils and then reinstalled slate by running (from the slate-master directory) python setup.py install.
So now when I import slate, I no longer get the error

ImportError: No module named 'utils'

BUT, now there is a new error:

ZipImportError Traceback (most recent call last)
in ()
----> 1 from slate import utils

ZipImportError: bad local file header: 'C:\Users\RobinG\AppData\Local\Continuum\Miniconda3\lib\site-packages\slate-0.5.2-py3.5.egg'

This is on Windows 7, Python 3.5.2, slate 0.5.2. Any suggestions?

[timClicks]

@dogfloss do you know if you uninstalled correctly?

As a workaround, if you try python setup.py develop, it will use a symlink. If you can verify that the first error goes away, I will get the code changed.

This is on Windows 10, Python 3.5., slate 0.5.2. Any suggestions?
Please help me out. I am new to Python programming.

@shyamiitk I had the same issue and I solved it by editing classes.py. Ironicely, functions that are supposed to be called in Python 3 crash in Python 3. You just remove them, and use the default case.

In classes.py, you edit lines 55-61:

if PYTHON_3:
    self.doc = PDFDocument()
    self.parser.set_document(self.doc)
    self.doc.set_parser(self.parser)
    self.doc.initialize(password)
else:
    self.doc = PDFDocument(self.parser, password)

to

self.doc = PDFDocument(self.parser, password)

and lines 69-72:

if PYTHON_3:
    page_generator = self.doc.get_pages()
else:
    page_generator = PDFPage.create_pages(self.doc)

to

page_generator = PDFPage.create_pages(self.doc)

I use Windows 10, Python 3.6.2 and Slate 0.5.2, and it seems to work fine now.

@canguezelhan I initially thought your code did the trick but after running into another error later (to do with reading unicodes) I have found that the original code worked provided I read the file in as binary to begin with using. with open(path,'rb') as f:

Just to clarify -

(1) This library has been unusable for 3+ years due to unresolvable dependency issues.

(2) Even when it works, this library only supports Python 2.7.

I have the same problem. My friend can use this code without any errors . He told me he didn't install anything. When i installed packages i get more errors idk

@sfsdfd There exist working forks of this repo. A script using slate is spitting out text from a PDF as I type. Check https://github.com/alkivi-sas/slate/tree/python3

@canguezelhan I have the same problem. Silly question but how can I find the classes.py to try out your solution? Thanks

[canguezelhan]

@darrencl https://github.com/timClicks/slate/blob/master/src/slate/classes.py You're welcome! :)

@canguezelhan hi, thank you for your response. I just installed slate (before I only installed pdfminer.six), but could not locate the file. I installed the slate using easy_install and as I am aware, it is just installing a file named slate-0.3-py3.6.egg in C:\Users\Darren\Anaconda3\Lib\site-packages. Any ideas where it is in my directory?

@BadrulAlom Hi, I was doing the same thing (i.e. opening the file as binary using 'rb' option), but having the error __init__() missing 1 required positional argument: 'parser', any solution?

Worked for me.
