Gensim: “C extension not loaded, training will be slow.”

问题

I am running gensim on Linux Suse. I can start my python program but on startup I get:

C extension not loaded, training will be slow. Install a C compiler and reinstall gensim for fast training.

GCC is installed. Does anyone know what I have to do?

Try the following:

Python 3.x

$ pip3 uninstall gensim    
$ apt-get install python3-dev build-essential      
$ pip3 install --upgrade gensim

Python 2.x

$ pip uninstall gensim    
$ apt-get install python-dev build-essential      
$ pip install --upgrade gensim
