Importing gensim causes Python 3.4 kernel crash

[Tom Vandermolen]

Just installed gensim today, but have been unable to import it successfully.  Whenever I try to execute the line:

import gensim

The system will grind for a moment, then a popup window will appear: 
"python.exe has stopped working 
A problem caused the program to stop working correctly. Please close the program."

I have tried to import using the Python shell and via an IPython notebook, with the same result each time.  Any ideas on how to fix this?

My system:
* Windows 7 (64-bit)
* Anaconda 2.3.0 (64-bit) (Python 3.4.1)
* gensim 0.12.0
* scipy 0.15.1
* numpy 1.9.2

Without knowing much more, try:

* download gensim from the github site

* conda remove gensim ... to remove gensim installs from anaconda

* python setup.py install ... from the gensim directory

Thanks for the response!  I think the gensim install was corrupted in some way.  I thought I had uninstalled it before, but had to run pip uninstall twice before it finally disappeared from my conda environment.

Reinstalling via conda seems to have cleared up the problem.

Doesn't "conda install gensim" install gensim 0.10.x ?

[Tom Vandermolen]

It does, so I suppose that doesn't help with monitoring the new release, sorry.  I'm in the just-checking-it-out mode right now with gensim, so I'm hestitant to mess around with my working setup....

The Python 2.7.x + Windows combination with or without Anaconda can be frustrating if C/C++ extension have to be built. Afaik, Python 3.4.x + Windows should be fine and "python setup.py install" should work. If you try it, "conda remove gensim" first.

[Parkway]

Alternatively, get a gensim 0.12.x .whl package for Windows from http://www.lfd.uci.edu/~gohlke/pythonlibs/#gensim and then do a "pip install <.whl>" from the download directory.

Okay, decided to try this and now the python.exe crashing is back.

1.  I uninstalled gensim 0.10.x using "conda remove gensim"; verified using "conda list" that gensim was uninstalled.
2.  I downloaded gensim-0.12.0rc1.tar.gz from https://pypi.python.org/pypi/gensim/0.12.0rc1#downloads
3.  I installed using "python setup.py install".  Did not notice any issues during the install.
4.  When running the line "from gensim import corpora, models, similarities" in IPython Notebook, python.exe crashed.
5.  When running "python setup.py test" from the command line, python.exe crashed again.  This is the output it generated before the crash occurred:

I've uninstalled and will try the wheel package you suggested next.

Just installed gensim 0.12.0 using the .whl file from Christoph Golke's page, and it seems to be working fine. 

[Parkway]

Great!

If you read the top of Christoph's page it maybe that ... Visual C++ 2010 (x64, x86, for CPython 3.3 and 3.4) redistributable packages ... are missing from your configuration which along with Cython are needed to compile C/C++ extensions.

[Tom Vandermolen]

Good point, that's given me problems in the past.  Thanks for your help!
