Dear @sgugger @patrickvonplaten If training on TPU, it is recommended to pad all examples of the dataset to the same length or make use of ). ( ) The T5 model was proposed in Exploring the Limits of Transfer Learning with a Unified Text-to-Text → Question Answering is a classical Natural Language Processing. I think we could add a run_qa_seq2seq.py to https://github.com/huggingface/transformers/tree/master/examples/pytorch/question-answering that is very similar to https://github.com/huggingface/transformers/blob/master/examples/pytorch/summarization/run_summarization.py (we would just need to adapt the dataset to choose from I think). input_shape: typing.Tuple[int] = (1, 1) How often do people who make complaints that lead to acquittals face repercussions for making false complaints? input_ids: typing.Optional[torch.LongTensor] = None Minimum number of pairings that make all quadruples.

In which case fine-tuning on it (again/more) would make sense again. batches to the longest example is not recommended on TPU as it triggers a recompilation for every batch shape that is If nothing happens, download GitHub Desktop and try again. If, however, you want to use the second We have used a trainer module to test the model and fine-tune it in the following cells.

It is trained using teacher # This is not needed for torch's T5ForConditionalGeneration as it does this internally using labels arg. Wasn't the T5 model also trained on BoolQ which would make this difficult and kind of fishy to test/evaluate because the later test data would not really be unseen data for the model? How to define intelligence amongst animals. ", "BLOOM has 176 billion parameters and can generate text in 46 languages natural languages and 13 programming languages. A transformers.modeling_tf_outputs.TFBaseModelOutput or a tuple of tf.Tensor (if This is a task involving a question being asked to a system from a set of documents or text and should be able to answer that question. one for the output of each layer) of shape (batch_size, sequence_length, hidden_size). You can see it listed in the model card on huggingface as well as Google's original paper. At BigScience, we explored the following research question: "if we explicitly train a language model on a massive mixture of diverse NLP tasks, would it generalize to unseen NLP tasks?" And the answer is yes! Can you charge and discharge a Li-ion powerbank at the same time? Extracting the major and minor axes values from the elliptic equation. https://github.com/huggingface/transformers/tree/master/examples/pytorch/question-answering, https://github.com/huggingface/transformers/blob/master/examples/pytorch/summarization/run_summarization.py, https://github.com/google-research/text-to-text-transfer-transformer/blob/3c58859b8fe72c2dbca6a43bc775aa510ba7e706/t5/data/preprocessors.py#L918, Supporting Seq2Seq model for question answering task. At inference time, it is recommended to use generate(). You may read about this T5 transformer here in one of my articles. This forces T5 to answer questions based on "knowledge" that it internalized during pre-training. See diagram 1 in the torch.FloatTensor (if return_dict=False is passed or when config.return_dict=False) comprising various There is a fine-tuned version of t5 for BoolQ which gives a more acceptable answer.
