What operating system are you using?

[ntugce]

Having a similar problem and I am on Ubuntu 16.04. Here is the problem:

import pycrfsuite Traceback (most recent call last): File "", line 1, in File "/home/softwares/anaconda3/lib/python3.6/site-packages/pycrfsuite/init.py", line 2, in from ._pycrfsuite import * ImportError: /home/softwares/anaconda3/lib/python3.6/site-packages/pycrfsuite/_pycrfsuite.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _ZTVNSt7__cxx1118basic_stringstreamIcSt11char_traitsIcESaIcEEE

@ntugce are you mixing anaconda-installed packages and pip-installed packages?

[ntugce]

Thanks for your quick response. I did not do anything particular than pip installing the python-crfsuite Pip installation works but then when I want to import pycrfsuite I get this error. Googling it I found this issue. But "conda install libgcc" did not do it for me.

[ntugce]

Okay, easy_installing the egg file worked for me, as you said perhaps something went wrong with the pip packaging. Thank you !

Sorry, I've tried to use the easy install method but It just doesn't seem to want to work for me. Traceback (most recent call last): File "C:/Users/dmurphy1/AppData/Local/Programs/Python/Python36-32/Lib/site-packages/usaddress/init.py", line 17, in import pycrfsuite File "C:\Users\dmurphy1\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pycrfsuite_init_.py", line 2, in from ._pycrfsuite import * ImportError: DLL load failed: The specified module could not be found.

Process finished with exit code 1

It seems like this has been an issue for a while but everybody who's figured it out doesn't have an reason why it starts to work all of a sudden. I've tried installing from whl and egg (pip & easy_install) any advice?

[kmike]

@murphyd2 something seems to be wrong with paths, as usaddress is installed for Python 3.6, while pycrfsuite is installed for Pythoin 3.7. I don't have much Windows experience, but I think they shouldn't both be in PYTHONPATH.

[murphyd2]

(by the way thanks for the quick response) import fail.txt Hmm okay so I uninstalled them from both interpreters and reinstalled from whl files (all using pip) and i'm still getting this error.

[kmike]

@murphyd2 could you try creating a virtualenv, and installing python-crfsuite there, to make sure you're starting from a clean state?

[murphyd2]

yep! I'll get back to you with the results pronto.

So, I'm still running into errors. FYI within site-packages for pycrfsuite (photo at end) I only have __pycache __, logparser,dumpparser, __ init, and then a PYD file called _pycrfsuite.cp37-win32 I'm assuming the end of _pycrfsuite is intentional there? Within __pycache __ i've got cpython files for only __init __ _logparser and _dumpparser.

Any thoughts?

@kmike I fixed this by installing with miniconda in a conda enviroment with python 3.6. works great. Thanks!
