ext embeddings are generated from the prompt input argument. A single vector from the
pooled and projected final hidden states.   encoder_hidden_states (torch.FloatTensor, optional) —
Pre-generated penultimate hidden states from the text encoder providing additional text conditioning.   negative_prompt_embeds (torch.FloatTensor, optional) —
Pre-generated negative text embeddings. Can be used to easily tweak text inputs (prompt weighting). If
