session with python-mode.el complains of void py-toggle-shells

[Myles English <mylesenglish@gmail.com>]

Hi,

I think it should be possible to execute a python block in a session
using python-mode.el but get this message:

"Symbol's function definition is void: py-toggle-shells"

Using the latest git head and opening this file with:

$ emacs -Q thisfile.org

then executing these src blocks in order, shows the problem:

#+BEGIN_SRC emacs-lisp
  (require 'org)
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((python . t)))
#+END_SRC

#+RESULTS:
| (python . t) |

* A heading

This works okay:

#+begin_src python :results output :session a
import sys
#+end_src

#+RESULTS:

Try with python3:

#+begin_src elisp
(setq org-babel-python-command "python3"
      py-python-command "python3"
)
#+end_src

#+RESULTS:
: python3

works also:

#+begin_src python :results output :session a
import sys
#+end_src

#+RESULTS:

Try using python-mode.el:

#+begin_src elisp
(setq org-babel-python-mode 'python-mode)
(load-file "/usr/share/emacs/site-lisp/python-mode.el")
#+end_src

#+RESULTS:
: t

#+begin_src python :results output :session a
import sys
#+end_src

Gives this *Message*:

org-babel-python-initiate-session-by-key: Symbol's function definition
is void: py-toggle-shells

Do I need to configure something else?

Thanks,

Myles
