ich will be summed with the time embeddings. Choose from None or
“text”. “text” will use the TextTimeEmbedding layer.   num_class_embeds (int, optional, defaults to 0) —
Input dimension of the learnable embedding matrix to be projected to time_embed_dim, when performing
class conditioning with class_embed_type equal to None.   upcast_attention (bool, defaults to False) —   resnet_time_scale_shift (str, defaults to "default") —
