On: Aquamacs 3.3 GNU Emacs 25.1.1 (x86_64-apple-darwin14.1.0, NS appkit-1344.72 Version 10.10.2 (Build 14C109)) of 2016-09-19 in mac osx sierra
i changed my ~/Library/Preferences/Aquamacs Emacs/Preferences.el with the below:
(setq python-version-checked t) (setq py-python-command "python3.5")
(eval-after-load "org" '(org-babel-do-load-languages 'org-babel-load-languages '((sh . t) (python . t) (emacs-lisp . t) (ditaa . t) )))
but it still fails to point to python 3.5. Thanks!
