How does batching work in pytorch

WebMar 22, 2024 · batch (potentially partially in parallel) is when you call something like prediction = model (input). Also it’s not clear to me which part of the calculation you mean when you say “backprop”. If you mean updating your model weights, this occurs when you call optim.step (), and this piece is independent of the size of the batches. (However, the The only thing we need to set to perform batch learning is to add an extra dimension to the input which corresponds to the batch size but nothing inside the network definition is going to be changed if we are working with batch learning.
