## Model in action

Fast usage with **pipelines**:

```python
from transformers import pipeline

qa_pipeline = pipeline(
    "question-answering",
    model="mrm8488/spanbert-base-finetuned-squadv1",
    tokenizer="SpanBERT/spanbert-base-cased"
)

qa_pipeline({
    'context': "Manuel Romero has been working very hard in the repository hugginface/transformers lately",
    'question': "How has been working Manuel Romero lately?"

})

# Output: {'answer': 'very hard in the repository hugginface/transformers',
 'end': 82,
 'score': 0.327230326857725,
 'start': 31}
```
