DISCLAIMER: If you see something strange, file a Github Issue and assign . It contains highly configurable models and training procedures that make it a very simple framework to use. When the number of candidates is equal to beam size, the generation in fairseq is terminated. Fairseq also features multi-GPU training on one or across multiple machines, and lightning fast beam search generation on both CPU and GGPU. the same error, but while using fairseq, and the answers were not helpful to me; and the exact same issue asked on the NVIDIA/Apex github issues section, but no response was given. If you have any new additional information, please include it with your comment! Transformers (modified) version v3.5.1 can be installed as follows: I modified SinusoidalPositionalEmbedding in transformers/src/transformers/modeling_bart.py to match the implementation in fairseq, since fairseq differs from HuggingFace in sinusoidal embeddings initialization and calculation of positional ids. decoder_input_ids: typing.Optional[torch.LongTensor] = None vocab_file = None sep_token = '' transformers.modeling_tf_outputs.TFSeq2SeqModelOutput or tuple(tf.Tensor).
