Guide to Torchmeta- A Meta-Learning library for PyTorch. Models in PyTorch are created from basic components called modules and each basic module represents a layer in the neural network containing both the computational graph and its parameters. However, some meta-learning algorithms require high-order differentiation to update the parameters via backpropagation. The list of tutorials is: Guide 1: Working with the Lisa cluster. I was mainly wondering if we should use the running statistics we used during meta-training or the batch statistics for the current task (during meta-evaluation). Does creating a data loader inside another data loader in pytorch slow things down (during meta-learning)? And there are exploration strategy, replay buffer and target networks involved to stabilize the training process. This subsection summarizes the code that is needed to create such training batches.
