Sorry I haven't been following along quite as closely as I probably should have... I booted into Linux to remove the issue of setting up python on my Windows partition. Are my results contrary to what's been happening to you? #+begin_src ~/Desktop/test.org * heading Using =:results output= #+BEGIN_SRC python :results output :session transect import numpy as np x = np.arange(12) print x #+END_SRC #+RESULTS: : : >>> [ 0 1 2 3 4 5 6 7 8 9 10 11] #+end_src #+begin_src ~/Desktop/test.org * heading I can also use =:results value= and it spits out an org table #+BEGIN_SRC python :results value :session transect import numpy as np x = np.arange(12) x #+END_SRC #+RESULTS: | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | #+end_src #+begin_src Emacs *transect* buffer >>> import numpy as np >>> x = np.arange(12) >>> print x [ 0 1 2 3 4 5 6 7 8 9 10 11] >>> >>> >>> >>> 'org_babel_python_eoe' 'org_babel_python_eoe' >>> #+end_src #+begin_src .emacs ;; Arch linux installs python3 by default, and python is bound to it ;; need to set this variable to make sure we're using python v2 (setq org-babel-python-command "python2") #+end_src $ python2 --version Python 2.7.6 M-x org-version Org-mode version 8.2.3c (release_8.2.3c-227-g54a64f @ /home/jwhendy/.elisp/org.git/lisp/) $ emacs --version GNU Emacs 24.3.1 I think the :session name -> a *name* session is still a bit goofy, but I at the very least I wanted to share that I don't get any hanging behavior and seem to get coherent results out of a python babel code block.
