I have Installed from Melpa ob-ipython on Ubuntu Xenial with Emacs 24. If I try to evaluate a source code like:

#+BEGIN_SRC ipython :session
%matplotlib inline
importmatplotlib.pyplot as plt
inport numpy as np
#+END_SRC

I get the following error:

No org-babel-execute function for ipython

What can I do to solve this problem?

It looks like adding (package-initialize) (require 'ob-ipython) to my .emacs solved the problem!

You need to update org-babel-load-languages. Try this:

(org-babel-do-load-languages 'org-babel-load-languages 
                             '((emacs-lisp . t)
                               (ipython . t)))

This is described in the Org Manual

  • Can you post a minimum working example of an init file that recreates your problem?
