  attention_mask ( torch.Tensor, optional) —
An attention mask of shape (batch, key_tokens) is applied to encoder_hidden_states. If 1 the mask
is kept, otherwise if 0 it is discarded. Mask will be converted into a bias, which adds large
negative values to the attention scores corresponding to “discard” tokens.   encoder_attention_mask ( torch.Tensor, optional) —
Cross-attention mask applied to encoder_hidden_states. Two formats supported:
