WebJul 7, 2024 · that we’re extracting the diagonals from the 2d matrices made up by the last two dimensions of T (so that this version would generalize to a hypothetical use case where T had multiple leading “batch” dimensions such as T of shape [batch_size, channel_size, size_n, size_n] ). It’s really just stylistic – and not necessarily a better style. Best.
