`hidden_states` and `attentions` because we didn't pass `output_hidden_states=True` or
`output_attentions=True`.

<Tip>

When passing `output_hidden_states=True` you may expect the `outputs.hidden_states[-1]` to match `outputs.last_hidden_states` exactly.
However, this is not always the case. Some models apply normalization or subsequent process to the last hidden state when it's returned.
</Tip>


You can access each attribute as you would usually do, and if that attribute has not been returned by the model, you
will get `None`. Here for instance `outputs.loss` is the loss computed by the model, and `outputs.attentions` is
`None`.
