Problem installing

[alxbar]

when I try to install via pip install -e git+git://github.com/spacy-io/sense2vec.git#egg=sense2vec
or via pip install sense2vec, I get following error message

>>> import sense2vec
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/alex/anaconda2/lib/python2.7/site-packages/sense2vec/__init__.py", line 2, in <module>
    from .vectors import VectorMap
ImportError: /home/alex/anaconda2/lib/python2.7/site-packages/sense2vec/vectors.so: undefined symbol: _ZTINSt8ios_base7failureB5cxx11E

I am using ubuntu 16.04 and python 2.7 with anaconda 4.2.9. (installed requirements-all.txt)
the problem did not occur on a mac sierra 10.12.1

I actually get a similar error but when trying to use SpaCy:

ImportError: /home/ties/anaconda3/lib/python3.5/site-packages/spacy/tokenizer.cpython-35m-x86_64-linux-gnu.so: undefined symbol: _ZTINSt8ios_base7failureB5cxx11E

I am also using ubuntu 16.04 but with Python 3.5 (Anaconda).

Have you figured out how to solve it?

[TiesdeKok]

After a bit of Googling I found the answer, it has to do with the version of libgcc in the Anaconda environment.

The error is solved after running conda install libgcc in the anaconda environment.

For me it just suddenly started working, I think I eventually have installed libgcc.

Yes I tried it also on my other PC (same setup same problem) and conda install libgcc solved the issue, thanks :).

I have the same problem even with libgcc. Created a new env with conda

conda create -n spacy python=3.5 ipython

and then install spacy (1.6.0) with pip (conda still has version 0.101.0)

pip install spacy

But I still get this error.
