How to get Hydra config without using @hydra.main()

Create config.yaml under the same root.

Connection:
    user: root
    passwd: xxxx
    db: xxxx
    host: xxxx
    port: xxxx

 

And conncect it.

from hydra.experimental import compose, initialize
initialize(config_path="./", strict=False)

cfg = compose("config.yaml")

conn = pymysql.connect(
    user=cfg.Connection.user,
    passwd=cfg.Connection.passwd,
    db=cfg.Connection.db,
    host=cfg.Connection.host,
    port=cfg.Connection.port,
    charset="utf8",
    use_unicode=True,
    )

 

• Error : GlobalHydra is already initialized, call GlobalHydra.instance().clear() if you want to re-initialize

Once GlobalHydra initialized, it doesn't need to initialize again. So in my case, I removed it.

#initialize(config_path="./", strict=False)
