Service name for Docker Compose remote interpreter in PyCharm 5.1 Beta 2

I've imported to PyCharm 5.1 Beta 2 a tutorial project, which works fine when I run it from the commandline with docker-compose up : https:// docs.docker.com/compose/django/

Trying to set a remote python interpreter is causing problems.

I've been trying to work out what the service name field is expecting: remote interpreter - docker compose window - http:// i.stack.imgur.com/Vah7P.png.

My docker-compose.yml file is:

version: '2'
services:
  db:
    image: postgres
  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

When I try to enter web or db or anything at all that comes to mind, I get an error message: Service definition is expected to be a map

So what am I supposed to enter there?

EDIT1 (new version: Pycharm 2016.1 release)

I have now updated to the latest version and am having still issues: .IOError: [Errno 21] Is a directory
