module not found on ipython notebook

Question

I have an ipython notebook which starts with

import sklearn

When I run it, I get :

ImportError: No module named sklearn


        

Answer 1

I was able to fix this error on Ubuntu by adding a cell to the top of the notebook appending the module directory to the path:

import sys
sys.path.append('/usr/lib/python2.7/dist-packages')

The path to add can be found when running pip install <something>, (such as numpy) and it tells you where each package is installed or already exists.

Answer 2

Is it possible that /usr/bin/python is actually a symlink?

The better solution is that you should be running your ipython notebook from a virtualenv that contains all the modules that you need.
