"WebApr 12, 2024 · padding_idx is indeed quite badly described in the documentation. Basically, it specifies which index passed during call will mean "zero vector" (which is quite often used in NLP in case some token is missing). By default no index will mean "zero vector", as you can see in the example below: " - Pytorch ignore_index
