Defaults List Overrides

Hydra versions prior to 1.1 supported overriding of Hydra config groups via the Defaults List in this manner:

defaults:
 - model: resnet50
 - hydra/launcher: submitit

As of Hydra 1.1, Config group overrides must be marked explicitly with the override keyword:

defaults:
 - model: resnet50
 - override hydra/launcher: submitit

The Defaults List is described here.

warning

Omitting the override keyword when overriding Hydra's config groups will result in an error in Hydra 1.2
