Within the IKW network, there is a local installation of gensim (which in turn depends on Numpy >= 1.4 (current version on IKW machines is 1.3) and Pyro >=4.1), residing in /net/data/CL/projects/wordspace/gensim_local to use it, change into this directory and run source bin/activate python This loads the libraries installed locally in this directory and starts the python interpreter. To stop using the virtual environment, simpy run deactivate In theory, you can copy the entire gensim_local folder to your machine and run it from there, however I won't guarantee that this works in practice. However, it is easy to create such a local environment yourself: # Skip this step if you already have virtualenv easy_install virtualenv # If you don't have sudo rights, install virtualenv locally: # mkdir ~/opt # easy_install --instal-dir opt virtualenv # Create a clean virtual environment virtualenv --no-site-packages myVirtualEnv # And activate it cd myVirtualEnv source bin/activate # Now, using pip, install the other stuff bin/pip install numpy bin/pip install gensim[distributed] bin/pip install Pyro4
