LSTM dropout - Clarification of Last Layer

In the documentation for LSTM, for the dropout argument, it states: introduces a dropout layer on the outputs of each RNN layer except the last layer I just want to clarify what is meant by “everything except the last layer”. Below I have an image of two possible options for the meaning. Option 1: The final cell is the one that does not have dropout applied for the output. Option 2: In a multi-layer LSTM, all the connections between layers have dropout applied, except the very top lay…

But in this post the figure shows it is not…
Which claim is true?
Thank you!
