Convert self to a tuple containing all the attributes/keys that are not None.

update([E, ]**F) → None.  Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

loss: Optional[Union[Array, ndarray, bool, number]] = None

replace(**updates)

Returns a new object replacing the specified fields with new values.

Bases: FlaxMaskedLMOutput

Base class for MoE model outputs.

Parameters

• last_hidden_state (chex.Array of shape (batch_size, sequence_length, hidden_size)) – Sequence of hidden-states at the output of the last layer of the model.

• hidden_states (tuple(chex.Array), optional, returned when output_hidden_states=True is passed or when config.output_hidden_states=True) –

  tp.Tuple of chex.Array (one for the output of the embeddings + one for the output of each layer) of shape (batch_size, sequence_length, hidden_size).

  Hidden-states of the model at the output of each layer plus the initial embedding outputs.

• attentions (tuple(chex.Array), optional, returned when output_attentions=True is passed or when config.output_attentions=True) –

  tp.Tuple of chex.Array (one for each layer) of shape (batch_size, num_heads, sequence_length, sequence_length).

  Attentions weights after the attention softmax, used to compute the weighted average in the self-attention heads.

• router_logits (tuple(chex.Array), optional) –

  tp.Tuple of chex.Array (one for each layer) of shape (batch_size, sequence_length, num_experts).

  The logits output of the router network, which are used to compute the mixture of experts.
