Hugging Face Forums Difference in memory efficiency in HF and fairseq Models Zhylkaaa October 23, 2020, 6:13pm #1 Hello, I've been reading this paper on mbart ( https://arxiv.org/pdf/2001.08210.pdf) and came across section 2.2 optimization where authors claim to have total batch size of 128K tokens per 32GB GPU.

I would argue that DeepPavlov to ParlAI is like Tensorflow to Pytorch. ), ( If you want to use it in version 0.9.x or 0.10.x, you need to change args.model.xxx to args.xxx in convert.py, since fairseq adopted the Hydra configuration framework in the latest version. ) If this issue is still present in the latest release, please create a new issue with up-to-date information. In addition, the beam search in the earlier versions has bugs.

Explanation: ParlAI is Facebooks #1 framework for sharing, training, and testing dialogue models for different kinds of dialogue tasks. If you wish to change the dtype of the model parameters, see to_fp16() and It was actually just for learning purpose, but since it was trained for many hours on multiple gpus, I though it would be good also for other if I put it to huggingface's models zoo if I am able to convert it. decoder_head_mask: typing.Optional[torch.Tensor] = None transformers.modeling_outputs.Seq2SeqSequenceClassifierOutput or tuple(torch.FloatTensor), transformers.modeling_outputs.Seq2SeqSequenceClassifierOutput or tuple(torch.FloatTensor). attentions (tuple(torch.FloatTensor), optional, returned when output_attentions=True is passed or when config.output_attentions=True) Tuple of torch.FloatTensor (one for each layer) of shape (batch_size, num_heads, sequence_length, sequence_length). The difference is that PyTorch-NLP is written to be more flexible.
