pytorch t5 text2text-generation transformers autotrain_compatible
# T5 for question-answering
This is T5-base model fine-tuned on SQuAD1.1 for QA using text-to-text approach

## Model training
This model was trained on colab TPU with 35GB RAM for 4 epochs

## Results:
| Metric      | #Value  |
|-------------|---------|
| Exact Match | 81.5610 |
| F1          | 89.9601 |

## Model in Action 🚀
```

question = "What is Valhalla ?"

get_answer(question, context)
# output: 'a majestic, enormous hall located in Asgard, ruled over by the god Odin'
