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.

Did you fix this problem? Exporting to ONNX works fine, but when using the exported ONNX file for sim2sim and pressing the ']' key, the robot just falls down immediately.
