Warning (emacs): Python shell prompts cannot be detected.
If your emacs session hangs when starting python shells
recover with `keyboard-quit' and then try fixing the
interactive flag for your interpreter by adjusting the
`python-shell-interpreter-interactive-arg' or add regexps
matching shell prompts in the directory-local friendly vars:
  + `python-shell-prompt-regexp'
  + `python-shell-prompt-block-regexp'
  + `python-shell-prompt-output-regexp'
Or alternatively in:

Hi shaief, I'm getting the same Warning when I launch the Python REPL. I've noticed that it happens in with WinPython (http://winpython.github.io/), but not with Anaconda. The warning appears but is harmless. Still its annoying, did you find a way around it? Thanks...

Same error on Linux.
