Hi all, I'm trying to implement both imitation and curriculum learning in my own learning environment but I encountered two errors: 1. SideChannelUtils underlined when I wanted to access values from the curricula I learnt this from the WallJumpAgent.cs, is this a correct way to access? 2. Value Error during training with demonstration, sth like ValueError: Cannot feed value of shape (8, 5) for Tensor 'teacher_action:0', which has shape '(?, 4)' Any ideas how to fix these? Thanks!
