some questions about Meta RL

[wow-ui]

I have some questions about the Meta RL part.

1. In maml.py, should the 'import TrochOpt' be 'import torchopt as TorchOpt'?
2. In the 'retrieve_cfg' method of the config.py , two ShadowHandMetaMT1 appear without the Meta RL task. Under the path 'tasks/shadow_hand_meta/', there are mt1, mt4 and ml1. Should the second ShadowHandMetaMT1 be ShadowHandMetaML1?
3. Is it normal for the ProMP algorithm (mamlppo) to have only tfevent files for training results and nothing else?

Looking forward to your reply.
