Problems with Imitation Manager in 5.7

Hello all!

I ran into troubles getting the IL part of the docs to work in 5.7. The regular manager and recording manager work fine, but if i try to feed the REC_Human into it, the output log tells me that the recording contains no valid training data and will be ignored. There was a change in nodes over the course of time and I wonder if these changes are responsible for the faulty behaviour? I attached the manager in questions here: 5.7 ImitationManager posted by anonymous | blueprintUE | PasteBin For Unreal Engine

Any hints on what to change to make it work as intended is greatly appreciated! If more blueprints are needed I’m happy to provide those.

Error Log after fixing schema inside recording - Pastebin.com - Errors I get after Inserting what i believe is the right Schema into the recording. Is this a python bug or something on my end I did wrong?

Imitation Manager 5.7 Fix posted by anonymous | blueprintUE | PasteBin For Unreal Engine Adding the communicator was the right approach and then I fixed it by changing the Trainer File Name inside Trainer Process Settings to learning_agents.train_behavior_cloning. Took me way too long to realize it was set to learning_agents.train_ppo as I copy pasted it from the PPO manager.
