encoder_outputs actually I have 1 more question while writing this: why there are 1024 pos_embeddings, when paper authors write about pre-training 512? for GLUE Finally, this model supports inherent JAX features such as: ( length_penalty = 1.0 (batch_size, sequence_length, hidden_size). ( Hidden-states of the encoder at the output of each layer plus the initial embedding outputs. ( 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. decoder_attention_mask: typing.Optional[torch.LongTensor] = None It's the same reason why people use libraries built and maintained by large organization like Fairseq or Open-NMT (or even Scikit-Learn). output_attentions: typing.Optional[bool] = None etc. I think @sshleifer and @valhalla are better equipped to answer your question. fairseq-to-huggingface Convert seq2seq models in fairseq (e.g., bart, all-share-embedding transformer) to the format of huggingface-transformers Most of the codes in convert.py are based on tomsherborne/example_bart_convert.sh. ( Bart Decoder Model with a language modeling head on top (linear layer with weights tied to the input embeddings) I have used it once during a hackathon, fine-tuning a conversational agent to the restaurant domain (so that users can check the menu and order the food they want), and the end result works like a charm.

Bart uses a standard seq2seq/machine translation architecture with a bidirectional encoder (like BERT) and a One of the most common applications of Fairseq among speech processing enthusiasts is wav2vec (and all the variants), a framework that aims to extract new types of input vectors for acoustic models from raw audio, using pre-training and self-supervised learning.
