AttributeError: 'PPOMultiActorCritic' object has no attribute 'alg'

[cherishyuan]

When I run the face smoothing result export export_policy_as_jit(algo.alg.actor_critic, exported_policy_path, exported_policy_name), the error AttributeError: 'PPOMultiActorCritic' object has no attribute 'alg' appears. I try to solve it but this error always occurs.
