or not to return a UNet2DConditionOutput instead of a plain
tuple.   cross_attention_kwargs (dict, optional) —
A kwargs dictionary that if specified is passed along to the AttnProcessor.   encoder_hidden_states_1 (torch.FloatTensor, optional) —
A second 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_attenti
