libcompose fails to create networks for version "2.0" and above

[prashanthjbabu]

The following docker compose file fails to work with libcompose

version: "2.0"
services:
postgres:
image: 'postgres:10.4'
container_name: postgres
restart: always
networks:
my-network:
networks:
my-network:
driver: "bridge"

It doesn't work for version 2.1,2.2 etc either . Replacing version to "2" works! The same yaml file above works on docker-compose CLI
