How To Get Started With the Model The developers of the Text-To-Text Transfer Transformer (T5) write: > With T5, we propose reframing all NLP tasks into a unified text-to-text-format where the input and output are always text strings, in contrast to BERT-style models that can only output either a class label or a span of the input. Our text-to-text framework allows us to use the same model, loss function, and hyperparameters on any NLP task. T5-11B is the checkpoint with 11 billion parameters. - Developed by: Colin Raffel, Noam Shazeer, Adam Roberts, Katherine Lee, Sharan Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu.

We can even apply T5 to regression tasks by training it to predict the string representation of a number instead of the number itself. See the blog post and research paper for further details. The model is pre-trained on the Colossal Clean Crawled Corpus (C4), which was developed and released in the context of the same research paper as T5. The model was pre-trained on a on a multi-task mixture of unsupervised (1.) and supervised tasks (2.). Thereby, the following datasets were being used for (1.) and (2.): 1.

Our systematic study compares pre-training objectives, architectures, unlabeled datasets, transfer approaches, and other factors on dozens of language understanding tasks. The framework introduced, the T5 framework, involves a training procedure that brings together the approaches studied in the paper. See the research paper for further details. The developers evaluated the model on 24 tasks, see the research paper for full details. For full results for T5-11B, see the research paper, Table 14.

Before `transformers` v3.5.0, due do its immense size, `t5-11b` required some special treatment. If you're using transformers `<= v3.4.0`, `t5-11b` should be loaded with flag `usecdn` set to `False` as follows: Secondly, a single GPU will most likely not have enough memory to even load the model into memory as the weights alone amount to over 40 GB. - Model parallelism has to be used here to overcome this problem as is explained in this PR. - DeepSpeed's ZeRO-Offload is another approach as explained in this post. See the Hugging Face T5 docs and a Colab Notebook created by the model developers for more context.
