Gensim未安装-Windows 8.1-Python

Question

I am trying to install Gensim but I am getting the errors displayed below. I am running Anaconda 2.1.0 with Python 2.7.8 and NumPy 1.9.0 on a Windows 8.1 machine. I already have the Windows SDK 8.1.

It says something about a deprecated NumPy version 1.7, which seems odd because I am running NumPy 1.9.0.

I also have a Anaconda3 installation with Python 3.4, though I removed those from my PATH in order to be able to run Python 2 in cmd, because I need to work on a project in Python 2. Running python --version returns "Python 2.7.8".

...and it goes on throwing up undefined references.

Answer 1

Turns out the problem was that the C libraries that Gensim needs are being compiled using a program called gcc.dll. Anaconda has this program built in, but so does the Haskell platform. As I've been using Haskell a while ago the Python installer was using the Haskell version of gcc.dll, instead of Anaconda's gcc.bat.

Removing my Haskell installation fixed the problem.

Answer 2

I'm using python 3.4 in win64. I met the same error when I install gensim. Then aftering trying many methods, I finally made it by "pip uninstall" numpy scipy and gensim, then "pip install" all three .whl files from the following site: http://www.lfd.uci.edu/~gohlke/pythonlibs/

Hoping can help others :)
