nd set of encoder hidden states with shape (batch, sequence_length_2, feature_dim_2). Can be
used to condition the model on a different set of embeddings to encoder_hidden_states.   encoder_attention_mask_1 (torch.Tensor, optional) —
A cross-attention mask of shape (batch, sequence_length_2) is applied to encoder_hidden_states_1.
If True the mask is kept, otherwise if False it is discarded. Mask will be converted into a bias,
which adds large n
