 dimension of the model input hidden_states   num_embeddings (int, optional, defaults to 77) —
The number of embeddings of the model input hidden_states   additional_embeddings (int, optional, defaults to 4) — The number of additional tokens appended to the
projected hidden_states. The actual length of the used hidden_states is num_embeddings + additional_embeddings.   dropout (float, optional, defaults to 0.0) — The dropout probability to use.
