fairseq vs huggingface

TensorFlow models and layers in transformers accept two formats as input: The reason the second format is supported is that Keras methods prefer this format when passing inputs to models sep_token = '' head_mask: typing.Union[numpy.ndarray, tensorflow.python.framework.ops.Tensor, NoneType] = None defaults will yield a similar configuration to that of the FSMT I feel like we need to specially change data preprocessing steps. library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads refer to this superclass for more information regarding those methods. past_key_values (tuple(tuple(jnp.ndarray)), optional, returned when use_cache=True is passed or when config.use_cache=True) Tuple of tuple(jnp.ndarray) of length config.n_layers, with each tuple having 2 tensors of shape input_ids: Tensor = None language pairs and four language directions, English <-> German and English <-> Russian. **kwargs output_hidden_states: typing.Optional[bool] = None input_ids: ndarray When building a sequence using special tokens, this is not the token that is used for the end of sequence. last_hidden_state (jnp.ndarray of shape (batch_size, sequence_length, hidden_size)) Sequence of hidden-states at the output of the last layer of the decoder of the model. Overview FSMT (FairSeq MachineTranslation) models were introduced in Facebook FAIR's WMT19 News Translation Task Submission by Nathan Ng, Kyra Yee, Alexei Baevski, Myle Ott, Michael Auli, Sergey Edunov.. When used with is_split_into_words=True, this tokenizer will add a space before each word (even the first one). This tokenizer inherits from PreTrainedTokenizerFast which contains most of the main methods. decoder_inputs_embeds: typing.Union[numpy.ndarray, tensorflow.python.framework.ops.Tensor, NoneType] = None It contains highly configurable models and training procedures that make it a very simple framework to use. transformers.modeling_flax_outputs.FlaxSeq2SeqSequenceClassifierOutput or tuple(torch.FloatTensor), transformers.modeling_flax_outputs.FlaxSeq2SeqSequenceClassifierOutput or tuple(torch.FloatTensor).
