When return_sequences=True, an output is generated for each timestep. So if there are 5 LSTM Cells in your layer, there will be 5 outputs, one per cell. When return_sequences=False, only the last output of the forward pass (located at timestep T-1) AND the last output...

the first one was to directly apply the Bidirectional wraper to the LSTM layer: encoder_inputs = Input(shape=(None, num_encoder_tokens)) encoder = Bidirectional(LSTM(latent_dim, return_state=True)) but I got this error message: --- AttributeError Traceback (most recent call last) <ipytho...
