*** jedi-mode is disabled in #<buffer *scratch*> ***
Fix the problem and re-enable it.

*** You may need to run "M-x jedi:install-server". ***
This could solve the problem especially if you haven't run the command yet
since Jedi.el installation or update and if the server complains about
Python module imports.
