Question about customized observation update (Mean * 0.0 + std?)

[percypeng5221]

Hi,
I'm a bit confused about this line here. Can you explain why you use mean * 0.0 + std here? Wouldn't it be std not changing throughout the whole training process?

HOVER/third_party/rsl_rl/rsl_rl/modules/actor_critic.py

Line 129 in 43ee08b

self.distribution = Normal(mean, mean * 0.0 + self.std)

Thanks!
Percy
