I quite not understand,

isn't just

if num_images == 0:
        cur_image_features = image_features[cur_image_idx]
        cur_input_embeds_1 = self.get_model().embed_tokens(cur_input_ids)
        cur_input_embeds = cur_input_embeds_1
        new_input_embeds.append(cur_input_embeds)
        new_labels.append(labels[batch_idx])

?
