Time steps I’m referring from going from each element in the input. Like if you fed a sentence as sequence the order of the words in that sentence matters. Hence why the pytorch docs say:
“For each element in the input sequence, each layer computes the following function”
Nn.LSTM is a window LSTM Aka rolled up LSTM
And would be option 2
Which sorry I misread you Tom thought you were disagreeing with that but read incorrectly and what I wrote was wrong it is multilayer for each time step😲
