Why no target network for DDPG actor?

[fdeng18]

Hi, thank you all for this great work!

I'm a bit curious about why you decided not to use a target network for the actor when computing the target Q values, as this differs from the original DDPG (and also TD3 and D4PG). Did you have some ablation study?

This repository Inherits drq-v2. That algorithm doesn't use target network. You'd better contact the author of drq-v2 (or drq-v1).
