dices to indicate different portions of the visual embeds.

            [What are token type IDs?](../glossary#token-type-ids) The authors of VisualBERT set the
            *visual_token_type_ids* to *1* for all tokens.

        image_text_alignment (`torch.LongTensor` of shape `(batch_size, visual_seq_length, alignment_number)`, *optional*):
            Image-Text alignment uses to decide the position IDs of the visual embeddings.

        output_attentions (`bool`, *optional*):
            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
            tensors for more detail.
        output_hidden_states (`bool`, *optional*):
            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
            more detail.
        return_dict (`bool`, *optional*):
            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
