Does use_curiosity still exist?

Hi! The examples doc mentions that one can enable curiosity for the Hallway scene by adding “use_curiosity: true” in the config yaml. I wanted to ask, is that still a thing, or is it superseded by the whole reward_signals syntax*? Thanks!

reward_signals:
        extrinsic:
            strength: 0.3
            gamma: 0.99
        curiosity:
            strength: 0.9
            gamma: 0.99
            encoding_size: 256

Yep, the use_curiosity has been replaced by the curiosity reward signal - looks like the documentation is a bit out of date.

Thanks! I’ll add a github issue.
